【Abstract】 An external cavity Raman laser is developed. A LD pumped actively Q-switched Nd: YAG laser is used as the pumping source at 532nm,Ba( NO3)2is used as Raman crystal. Output wavelengths are 563. 6nm,598. 7nm and 638. 6nm. The parameter of this Raman laser is measured. The maximum conversion efficiency and output energy of the first-Stokes pulse are 30. 3% and 1. 3mJ. The maximum conversion efficiency and output energy of the second-Stokes pulse are 13. 6% and 0. 6mJ.更多还原
