| Abstract: | Based on the self-stimulated Raman scattering of Nd:YVO4 laser crystal, combined with Cr:YAG passive mode-locking technology and frequency doubling technology, compact 1176 nm and 588 nm yellow laser mode locking was realized. A folded laser cavity with three mirrors and an output coupler with 10% transmittance were designed in the laser diode end-pumped laser. The Nd3+ concentration and length of the Nd:YVO4 crystal were 0.2% and 10 mm, respectively, and the initial transmission of Cr:YAG at 1064 nm was 67%. At 10 W incident pump power the average output power was 123 mW and the duration of Q-switched envelope was only 6.0 ns with the mode-locked pulse repetition rate of 1.0 GHz. The average output power of 588.2 nm yellow laser was about 8 mW. An effective method for achieving mode-locked yellow lasers was provided. |
