Nd: YAG Crystal

UV & IR Optics Nd:YAG(Neodymium­doped Yttrium Aluminium Garnet) laser crystal provides the laser system designer with the most versatile solid state laser source in use today. With thousands of systems in NLO Crystals daily use, Nd:YAG continues as the best of the rare earth garnet laser materials characterised by four level laser operation, permitting low threshold pulse or CW operation. Nd:YAG laser rods Laser Crystals produce efficient laser output at 1064nm. The systems designer can select from several levels of dopant concentration to optimize laser performance.
