Dual-wavelength actively Q-switched diode-end-pumped ceramic Nd:YAG/BaWO_4 Raman laser operating at 1240 and 1376nm

摘要

Based on different Raman shifts, efficient dual-wavelength Raman operations within a diode-end-pumped actively Q-switched ceramic Nd:YAG/BaWO_4 intracavity Raman laser is demonstrated for the first time. At a pump power of 22.3W and a pulse repetition rate of 10kHz, the maximum output power of 869 mW and 512mW for the first Stokes at 1240nm and for the second Stokes at 1376nm were obtained. The pulse widths of the first Stokes and the second Stokes were 16 ns and 2.6ns, respectively.
