Cr, Tm, Ho:YAG (2080nm)
(Chromium, Thulium, Holmium doped Yttrium Aluminum Garnet)
Applications
Surgery, Dentistry, Atmospheric Testing
CTH: YAG Advantages
High-efficiency 2 µm source
- Cr-Tm transfer quantum efficiency approaching 2
- Operates well at room temperature
- May be flashlamp or diode pumped
Laser diode sources can be pump the strong 780nm Tm3+ ion absorption line
- Chromium doping not necessary for diode-pumped applications
- Pump linewidth of 4nm; 4 times wider than the corresponding Nd:YAG diode-pump linewidth
Operates in a relatively eye-safe wavelength range
- Should lead to military and scientific applications in coherent radar and range-finding
