Here we propose an efficient diode-end-pumped actively Q-switched 1176-nm Nd:YAG/Nd:YVO 4 hybrid gain intracavity Raman laser. By virtue of the construction of a coaxial double crystal, the laser not only can operate efficiently at low pulse repetition frequencies (PRFs), thereby realizing relatively high-energy and high-peak-power pulsed output, but also is capable of generating a high average output power at high PRFs. A maximum pulse energy of 0.54 mJ for the 1176-nm Stokes light is achieved at the PRF of 10 kHz, and the maximum average output power up to 9.80 W is obtained at the PRF of 100 kHz, while the incident pump power is 42.0 W.
