A promising method for generation of relatively high-power and tunable yellow light based on optical parametric oscillator has been proposed and experimentally demonstrated. In the premise of optical efficiency, the tuning range of the yellow light is over 1.5 nm. Under the incident pump power of 21.9 W, average output power of 1188 mW and peak power of 2.9 kW at 575 nm are 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.
