Ho:Cr:Tm:YAG - Holmium, Chromium, Thulium Co-doped Yttrium Aluminum Garnet
Introduction
Holmium, Chromium, Thulium Co-doped Yttrium Aluminum Garnet (Ho:Cr:Tm:YAG) is a high efficient laser material which lases at 2.1 µm. It has wide applications in surgery, dentistry, atmospheric testing, etc.
CASTECH's laser crystal Ho:Cr:Tm:YAG is featured by
• High slope efficiency
• Pumped by flash lamp or diode
• Operates well at room temperature
• Operates in a relatively eye-safe wavelength range
