FAQ
Laser Crystals Selection Questions
Which crystal is used for 1064 nm lasers?
Nd:YAG is one of the most common choices for 1064 nm solid-state lasers. Nd:YVO4 is also used in compact diode-pumped laser systems.
What is Cr:YAG used for?
Cr:YAG is commonly used as a passive Q-switch for generating short pulses in Nd:YAG and Nd:YVO4 laser systems.
Can ATR supply coated crystals?
Yes. Coating requirements such as AR or HR coating should be specified with wavelength, surface, damage threshold and laser configuration.
