CTH:YAG
Cr:Tm:Ho:YAG (CTH:YAG) is an excellent crystal that emits 2.1μm wavelength laser and is widely used in medical, military and meteorological fields. WISOPTIC uses high-purity raw materials and sophisticated technology to produce high-quality CTH:YAG crystals. This crystal is capable to output high pulse energy and is suitable for repetitive frequency operation. WISOPTIC provide laser rods with diameters of 3 to 6 mm and lengths of 50 to 120 mm.
Features of CTH:YAG
-High slope efficiency, room temperature operation
-Suitable for lamp pumping or LD pumping
-Safe for human eyes
