Key Features:
- Emission at 2 μm wavelength
- Efficient pumping with high-power AlGaAs laser diodes
- Narrower absorption bandwidth compared to Tm:YAP
- Direct linearly polarized output
- Significant applications in medical and military fields
Description: Tm:YAP is an essential crystal for lasers emitting in the 2 μm wavelength range. Similar to Tm:YAP in physical and chemical properties, Tm:YAP crystals feature a 795 nm pump absorption band which is better matched with high-power AlGaAs laser diodes. Compared to Tm:YAP, Tm:YAP has a narrower absorption bandwidth (4 nm), higher efficiency, and the ability to directly emit linearly polarized light. These attributes make Tm:YAP crystals valuable in medical and military applications.
