Nd YLF Crystal
• Excellent internal quality
• Numerous options in size and doping level
• Precise orientation (deviation < 1°)
• Top quality of surface polishing
• Competitive price
• Mass production, quick delivery
Nd:YLF is an excellent crystal that is very suitable for working in mode-locked mode to obtain short pulse laser. Nd:YLF has very small thermal lens effect (much smaller than YAG crystal), wide fluorescent line, and can generate linear-polarized beam. The relatively small stimulated emission cross section of Nd:YLF makes it suitable for continuous work with low threshold. Nd:YLF crystal has obtained important applications in inertial confinement laser fusion research projects. WISOPTIC use high-purity raw materials, chemical reaction atmosphere and special equipment to grow high-quality Nd:YLF crystals, and provide various specifications of crystal rods and crystal strips.
