We present a highly efficient ring-cavity all-solid-state BaWO Raman laser generating at both the long-shift (ν=925 cm) and short-shift (ν=332 cm) Raman lines under external picosecond synchronous pumping at the wavelength of 1063 nm. Very high slope efficiencies and output pulse energies of 68.8% and 103 nJ at the ν-shifted Stokes wavelength of 1179 nm, and 38.6% and 53 nJ at the (ν+ν)-shifted Stokes wavelength of 1227 nm have been achieved. Self-mode locking of the (ν+ν)-shifted Stokes field under intracavity pumping by the ν-shifted Stokes field allowed to realize 12-fold shortening of the 1227 nm radiation pulse down to 3 ps close to the shorter dephasing time of the ν Raman line at the output pulse peak power 1.5 times higher than the pump peak power.
我们展示了一种高效的环形腔全固态 BaWO 拉曼激光器，在外部皮秒同步泵浦 1063nm 波长下，可在长波移（ν=925cm）和短波移（ν=332cm）拉曼线同时产生激光。在ν移斯托克斯波长 1179nm 处，获得了 68.8%和 103nJ 的高斜率效率和输出脉冲能量，在（ν+ν）移斯托克斯波长 1227nm 处，获得了 38.6%和 53nJ 的高斜率效率和输出脉冲能量。腔内 ν 移斯托克斯场对（ν+ν）移斯托克斯场的自模式锁定，允许将 1227nm 辐射脉冲缩短至 3ps，接近 ν 拉曼线较短的相消时间，输出脉冲峰值功率比泵浦峰值功率高 1.5 倍。
