Ho:Cr:Tm:YAG is a high efficiency laser material which lasers at 2.1µm. It has wide applications in medical, military and meteorology fields.
- May be flash lamp or diode pumped
- Very high slope efficiency
- Operates well at room temperature
- Operates in a relatively eye-safe wavelength range High efficiency
Basic Properties:
The Sellmeier equations (l in µm for YAG):
n ^2 = 2.08745 + 1.2081 l ^2 /(l^ 2 - 0.02119 )+ 17.2049 l ^2 /(l ^2 - 1404.45 )
