A promising method for generation of relatively high-peak-power and high-energy yellow light based on doubling actively Q-switched Nd:YAG-Nd:YVO4 hybrid gain intracavity Raman laser at 1176 nm has been proposed and experimentally demonstrated for the first time. Under the incident pump power of 42.0 W, pulse energy of 0.37 mJ and peak power of 75 kW at 1176 nm were generated in our experiment.
Efficient 588-nm yellow laser with high pulse energy and peak power is generated based on an intracavity frequency doubled Q-switched Nd:YVO4 self-Raman laser. The cavity is elaborately designed to ensure high conversion efficiencies in both Raman and second harmonic generation processes, and meanwhile mitigate the thermal load deposited in gain medium so as to help improve power scalability. At the pulse repetition frequency of 60 kHz, 6.33 W of 588-nm yellow output is obtained under 30.3-W incident pump. The pulse energy of 167 μJ and peak power of 33.4 kW are also obtained at 30 kHz.
