CTH:YAG laser crystal
Product Description
CTH:YAG
Ho:Cr:Tm:YAG is an excellent crystal emitting 2.1μm wavelength laser, which is widely used in medical, military and meteorological fields.
Suitable for lamp pumping or laser diode pumping. The crystal has high slope efficiency, works at room temperature, and the laser working wavelength is relatively safe for human eyes.
