Yb:YAP Chemical formula is Yb:YAlO3,Yttrium orthoaluminate activated with Yb3+ ions doped. It is mostly used in diode pumped high-power ultrafast lasers and the emission spectrum is around 1 um, also it’s scintillators. Yb:YAP is a Infra-red laser crystal, as a result of high threshold of pump, Yb:YAP has a widly used in application. In the continuous-wave state, the upper output power could be generated using the b-cut and c-cut Yb:YAP, and the output power of a-cut is lower. Due to the broad emission bandwidth and high thermal conductivity, Yb:YAP crystal is a gread laser for high power laser operation in CW and plsed regimes.
Yb:YAP crystal–diode pumped high-power ultrafast lasers
Yb:YAP crystal is a potentially useful polarized laser gain medium in laser-diode-pumped solid-state configurations. Yb:YAP crystals is used in large avalanche photodiodes, as the best photosensors are appearanced to be hopeful for future applications in neutrino physics.
