CASIX Introduces New Line of Nd:GdVO4 Laser Crystals; Crystals Are Ideal Laser Host Materials for DPSS Micro/Mini Lasers.FUZHOU, China -- CASIX, Inc., a leading manufacturer of high quality crystal and precision optics products, announced the introduction of Neodymium neodymium (nē'ōdĭm`ēəm), metallic chemical element; symbol Nd; at. no. 60; at. wt. 144.24; m.p. about 1,021°C;; b.p. about 3,068°C;; sp. gr. 7.004 at 20°C;; valence +3. Neodymium is a lustrous silver-yellow metal. Doped Gadolinium gadolinium (gădəlĭn`ēəm), metallic chemical element; symbol Gd; at. no. 64; at. wt. 157.25; m.p. 1,312°C;; b.p. 3,233°C;; sp. gr. 7.898 at 25°C;; valence +3. Vanadate van·a·date n. Any of three anions, VO3, VO4, or V2O7, containing pentavalent vanadium. [vanad(ium) + -ate2.] Noun 1. (Nd:GdVO4) laser crystals for the solid state laser market. Nd:GdVO4 crystals are ideal laser host materials for diode pumped solid state (DPSS DPSS Diode-Pumped Solid-State (laser) DPSS Department of Public Social Services DPSS Distributed-Parallel Storage System DPSS Datapath Synthesis System DPSS Data Processing Subsystem DPSS Digital Precision Strike Suite ) micro/mini lasers because of their high power output, high slope efficiency, good thermal conductivity, low lasing threshold and high laser-induced damage threshold. Nd:GdVO4 crystals have a large stimulated emission cross section at laser wavelength and a high absorption coefficient and wide bandwidth at pump wavelength, but have a low dependency on pump wavelength and produce a strongly polarized A one-way direction of a signal or the molecules within a material pointing in one direction. laser output. Nd:GdVO4 has a higher slope efficiency than Nd:YAG crystals and better thermal conductivity and higher power output than Nd:YVO4 crystals. The Nd:Doping level of Nd:YVO4 crystals is 0.1-4.0 atomic percent, wavefront distortion is less than lambda/8 at 633 nanometers (nm), orientation of a-cut is plus or minus 0.5 degrees and the dimensional tolerance is plus or minus 0.1 millimeter (mm). The performance of Nd:GdVO4 laser crystals and its advantages, as compared to Nd:YVO4 and YAG crystals, can be seen in the chart in the press release on the CASIX website: www.casix.com.
