Emission and excitation spectra of Er-doped YAP crystals reveal a broad emission band in the eye-safe region, with peaks around 1545 and 1608 nm. Pump bands are 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 eye-safe regime. Yttrium aluminum perovskite (YAP) is expected to be a 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 a large emission cross-section in 3 μm, three times …
