  • Nd:YAG Crystal is the most widely used solid state laser crystal. Nd:YAG laser crystal are wildly used in all types of solid-state laser systems-frequency-doubled continuous wave, high-energy Q-switched, and so forth. Its good fluorescent lifetime thermal conductivity and physical strengths makes it suitable for high power lamp pumped laser.

  • Anti-reflection coatings are available at your specified wavelength.
  • Be sure to wear laser safety goggles when checking optical path and adjusting optical axis.
  • To inquiry or order a finished Nd:YAG laser rod, please specify the specification listed above, for common application, we only need to know the main specification: Nd-dopant concentration, sizes, and coating. For special request, please specify specification in details for evaluation and fabrication.
