Tm:YAP
Tm:YAP is the best LD-pumping laser crystal of 2μm range for its 795nm adsorption band easily accessible with high power AlGaAs diode, high quantum efficiency, good physical, chemical and optical properties, linearly polarized output and wider absorption band of 4nm than Tm:YAG. It can be used in all-solid-state laser of 2μm range in medicine and military fields.
■ Advantages of Tm:YAP Crysta：
Good physical, chemical and optical properties
Higher efficiency at 2μm range compared to Tm:YAG
Linearly polarized output beam
Wide absorption band of 4nm compared to Tm:YAG
More accessible to 795nm with AlGaAs diode than the adsorption peak of Tm:YAG at 785nm

Note:
There are 2 kinds of method to define the space group of YAP crystal, respectively Pnma and Pbnm.
The a axis defined in Pbnm is equivalent to the c axis in Pnma;
The b axis defined in Pbnm is equivalent to the a axis in Pnma;
The c axis defined in Pbnm is equivalent to the b axis in Pnma.
