We report on a diode-pumped, Q-switched intracavity-Raman-shifted Nd-doped yttrium-aluminum-perovskite (Nd:YAP) laser using potassium titanyl phosphate (KTP) or potassium titanyl arsenate (KTA) nonlinear crystals to produce eye-safe radiation. In both cases, we obtained simultaneous laser emission at two wavelengths corresponding to distinct Raman gain peaks and different Stokes orders for the nonlinear crystal used. From the Nd:YAP/KTP laser source, we obtained 3 ns pulses of combined 21 kW peak power at 1478 and 1503 nm. From the Nd:YAP/KTA laser source, we obtained up to 220 mW total average output power, equally split between 1474 and 1480 nm emission lines.
我们报道了一种二极管泵浦、调Q内腔拉曼频移掺钕钇铝钙钛矿（Nd:YAP）激光器，该激光器使用磷酸钛氧钾（KTP）或砷酸钛氧钾（KTA）非线性晶体来产生对眼睛安全的辐射。在这两种情况下，我们都获得了对应于所用非线性晶体不同拉曼增益峰和不同斯托克斯阶数的两个波长的同时激光发射。从Nd:YAP/KTP激光源，我们在1478和1503 nm处获得了峰值功率为21 kW的3 ns组合脉冲。从Nd:YAP/KTA激光源，我们获得了高达220 mW的总平均输出功率，在1474和1480 nm发射线之间平均分配。
