摘要: 实现了以c切Nd:YVO4晶体作为激光增益介质，b切KGW和a切YVO4为拉曼晶体的半导体泵浦主动调Q双频移同步振荡的拉曼激光器的高效运转，得到YVO4晶体在890 cm−1处1178 nm和KGW晶体在901 cm−1处1180 nm的一阶斯托克斯光的双波长同步脉冲输出，当入射泵浦功率为8.37 w，脉冲重复率为15 kHz时，由1178和1180 nm光组成的拉曼激光平均输出最高为1.45 w。
Abstract: The efficient operation of a semiconductor-pumped actively Q-switched dual-frequency-shifted synchronous oscillation Raman laser was successfully demonstrated, employing a c-cut Nd:YVO4 crystal as the laser gain medium in conjunction with b-cut KGW and a-cut YVO4 crystals serving as Raman crystals. The synchronous dual wavelength pulse output of 1178 and 1180 nm first-order Stokes light corresponding to 890 cm−1 Raman shift in YVO4 and 901 cm−1 Raman shift in KGW is obtained. When the incident pump power is 8.37 w and the PRF is 15 kHz, the average output Raman laser composed of 1178 and 1180 nm lines is 1.45 w.
