MEGATRENDS IN MUNICH: E-mobility and autonomous driving will be hot topics at Laser World of Photonics in Munich, from 24 to 27 June.

This year's Laser World of Photonics will have a particular focus on electro-mobility and autonomous driving, two global megatrends that are expected to grow dramatically over the coming decade.

The laser and imaging technology on show at this year's exhibition will play a crucial role in breaking into these mass markets, particularly in the efficient mass production of electric vehicles, as well as enabling improved safety via smart sensors.

Market observers anticipate that by 2025, one in every four new cars worldwide will be electric-propelled. And the forecasts for 2030 are for an electro-mobility market share of between 50 and 75 per cent.

Laser technology provides the necessary accuracy and flexibility for the production of electric vehicles, from the welding of hairpins and the cutting of electrical sheets for electric motors, to the welding of connections in battery cells and the joining of dissimilar materials in lightweight vehicle designs.

Application panels

A dedicated application panel: 'No E-Mobility without Laser Technology' has been added to the range of presentations this year. The new panel will take place on Tuesday 25 June from 3 to 5.20pm in hall A3, and will be chaired by Dr Hans-Joachim Krau[beta], of Bayerisches Laserzentrum, Dr Gunter Ambrosy, of Trumpf, and Dr Alexander Olowinsky, of the Fraunhofer Institute for Lasertechnology ILT. The preexisting Lasers in Manufacturing (LiM 2019) section of the Laser World of Photonics Congress--run in parallel with the trade show--will also include presentations on how lasers can be used to facilitate e-mobility. Other laser materials processing application panels also taking place in hall A3, include:

* Modelling and Simulation of Laser Material Processes (Monday 24 June, 10am to 12.20pm)

* Perspectives and challenges for applications with Ultrashort Pulsed Lasers (Monday 24 June, 2.40 to 5pm)

* Smart Production of Metallic Parts by Additive Manufacturing (Wednesday 26 June, 10am to 12.20pm)

* Machine Intelligence and the Role of Photonics (Wednesday 26 June, 3 to 5.20pm)

* Lasers in Microelectronics: The Future is digital (Thursday 27 June, 10am to 12.20pm)

Special show: Photonics in Production

Topics including battery manufacturing and laser beam welding with blue light (more on page 24)--a new trend in laser processing identified to be especially suited to the field of e-mobility--will be showcased at the 'Photonics in Production' exhibit in hall A3, at booth 251.

Here, 300m2 of floor space will be dedicated to providing a comprehensive view into current trends and research findings in the field of laser material processing. Two live demonstrations will be given at the exhibit, one on high-efficiency welding with blue light, and the other on measuring welding depths using OCT and machine learning technologies.

Guided tours

This year the guided tours--introduced in 2017--will be based on the topics discussed in the applications panels. Tours are approximately two hours long and will begin at the Photonics in Production exhibit.

The topics of the upcoming tours, which require advanced registration, are:

* Inline process monitoring of laser welding processes (Tuesday 25 June, 9.30am)

* Guidance and shaping of high power laser radiation (Tuesday 25 June, 1.30pm)

* Current trends in laser drilling (Wednesday 26 June, 10am)

* Laser beam welding using visible laser radiation (Wednesday 26 June, 2pm)

Encouraging young talent

The trade fair continues to support the relationship between industry and academia, with activities such as the Makeathon, which made its debut in 2017. Around 80 to 100 students--from Germany and abroad--have the chance to demonstrate their photonics expertise by developing innovative solutions using the technology over a 24-hour period. The solutions are then presented.

Katja Stolle, exhibition director for the trade fair, said this event has been moved to a more central location in its exhibition hall this year, further highlighting the event and encouraging more attendees to stop by and learn about the projects undertaken by the students.

The organisers of the trade fair are also encouraging students to visit exhibition booths in greater numbers, with a new 'QR Rally', where certain exhibition stands throughout the halls will feature a scannable QR code that students can capture with their smartphones.

The code will then lead them to a set of questions that they can answer and discuss with exhibitors.

Both the Makeathon and the ever-growing Start-Up Pavilion, which offers discounted exhibitor rates for new companies looking to make their market debut, will be located in hall B2.

Hall B3, Booth 103

Nuburu will be presenting its high-brightness 500W blue (450nm) diode laser, the AO-500, which offers deeper penetration depth in materials processing applications involving gold, aluminium, and copper, among other metals. The blue light is absorbed much more by these reflective materials than the infrared wavelengths of conventional industrial lasers.

The efficiency and quality of materials processing applications are driven by power density. Increasing power density by a factor of four increases weld depth more than one-and-a-half times and increases the weld speed three to four times.

The AO-500 has an innovative design that individually aligns each of the output beams from sixteen multi-diode packaged chips, offering a high brightness. Early adopters are already leveraging the advantages of the high power and brightness in applications such as battery fabrication, automotive component production, e-mobility device fabrication, and electronic packaging.

OPI Photonics

Hall A3, Booth 217

OPI Photonics, an Italian innovative SME based in Torino, will be showcasing its line of beam switches and couplers for fibre lasers up to 10kW. These devices are essential in complex production lines, either for sharing the same fibre laser resource among different workstations (laser switches for time or power sharing) or to keep the process cable separated from the laser feeding fibre (laser couplers).

Fibre laser manufacturers can integrate couplers and switches inside their sources as a value-added option; system integrators can find the right input-output fibre combination yielding the most effective solution for their production line. Both devices are fully customisable and OPI can provide its expertise to identify the best solution. The equipment is PL-e certified.


Hall B2, Booth 216

PicoQuant will be presenting the latest additions to its photonics portfolio, the main highlight being the new Taiko PDL M1, a smart picosecond pulsed laser driver that can be used in combination with the laser heads of the firm's LDH series.

It enables the reading out and adjustment of many parameters on the fly, either through a local one-button interface, or remotely via a PC. These parameters include repetition rate, operation temperature, or even fully calibrated and linearised optical output power.


Hall A2, Booth 225

Scanlab will be highlighting its new encoder-based scan system ExcelliSCAN 20 at the show, which through smaller spots and large image fields enables the smallest patterns in micro structuring to be made using lasers. The scan system offers an increased working distance, allowing for more flexibility in highpower laser applications. Its intelligent SCANahead control dynamics increase productivity --particularly in 3D printing.


Hall A3, Booth 411

Sisma will be showcasing its Power Ramp software function, developed to optimise laser welding processes, specifically at two critical points--the start and end of the welding process.

Power Ramp operates at the start of the welding process by reducing the power supplied by the laser beam and gradually increasing it until the selected nominal value is reached. In the final phase of the welding process, Power Ramp operates inversely, reducing the nominal power delivered by the laser beam to obtain a gradual shutdown.

By modulating the power delivered by the laser beam in the initial and final phases of a welding process, Power Ramp is able to avoid the onset of porosity and cracks, marginal incisions--surface depressions that can be generated at the end of the weld bead--as well as prevent the formation of any other aesthetic and functional defects.

In addition to Power Ramp, Sisma will also be showcasing its MYSINT 100 metal 3D printer, and multiple vision systems for process monitoring at its booth.


Hall A3, Booth 400

TBH will be exhibiting its energysaving, low-maintenance, extraction systems for protecting employees and machines from even the smallest particles of laser fumes. The systems feature a noise-reducing engine and powerful control electronics, as well as offer a high filter quality that enables them to operate even in closed systems.

In addition to improving air quality and promoting employees' health, the extraction systems improve the cleanliness of laser processing, helping improve cut quality and the precision of machining. The modular design of TBH's extraction systems enables them to be adapted to different laser processes.


Hall A3, Booth 118

Extraction and filtration firm ULT will be introducing its new digital customer service FireCS, which provides access to fume extraction units via LAN/WLAN through a special webserver. This will allow customers to read out device data, filter saturation, performance data, or the next maintenance date. A specifically designed online portal will enable users to easily access device information, exchange system data with ULT, or even order replacement filters for dedicated units. Furthermore, it is planned that laser processing systems will be able to control and communicate with fume extraction devices in the near future.

ULT experts will also be on EVENT FOCUS: LASER WORLD OF PHOTONICS hand to provide information on how to guarantee safety for employees, manufacturing plants, product quality and complete processes.

ULT offers a range of both turnkey and customer specific systems to remove hazardous airborne pollutants from laser smoke or laser dust. In addition, the firm has a wide portfolio of extraction and filtration solutions for additive manufacturing, for air and gas cleaning, as well as post-processing issues.


Automated Beam Profiling for Manufacturing

Measure critical beam parameters in industrial environments at high power levels with Ophir BeamWatch Integrated. The solution was developed for use in automated production lines and is based on Ophir's noncontact laser measurement technology. BeamWatch Integrated accurately captures and analyses focal spot data of industrial lasers for wavelengths from 980 to 1,080nm. The system provides real-time measurements of focused laser beams with a power density that is too high for traditional measurement devices. Because there is no contact with the focused beam, there is no wear on the instrument, making it ideal for 24/7 use in production environments. Beam parameters measured include focus spot width and location, focal shift, centroid, M2, divergence, beam parameter product, Rayleigh length, beam tilt angle and absolute power.

* Real-time measurement

* Focal shift detection

* Laser measurement during loading/unloading

* Power meter with integrated Profinet interfaces

* Limit values can be set to trigger actions

* All parameters are analysed and stored
