Emission and excitation spectra of Er-doped YAP crystals reveal a broad emission band in the eyesafe region with peaks around 1545-nm and 1608-nm and pump-bands suitable for common 800-nm and 970-nm diode lasers, suggesting YAP as a candidate crystalline host for diode-pumped laser in the 1.5-μm eyesafe regime.
Yttrium aluminum perovskite (YAP) is expected to be suitable host material for efficient laser emission owing to higher thermal conductivity (∼13.3 W m−1 K−1)) good mechanical properties, and lower photon energy compared to YAG, Y2O3, and Lu2O3) ，Er:YAP exhibits the large emission cross-section in 3 μm, which was three times larger than that of Er:YAG. Highly doped Er:YAP can emit 2.73µm wavelength laser, and lowly doped Er:YAP crystal emits 1.66µm laser. Moreover, Er:YAP is one of the most promising laser materials, and can provide high-power mid-IR coherent beam.
- Higher thermal conductivity
- Lower phonon energy
- Good mechanical properties
- Abundant energy level structure
- High doping concentration
- Eyesafe Glass
