Problems solved by technology

[0003] The purpose of the present invention is to solve the problems in the above-mentioned prior art, such as the thermal effect of the laser medium and the frequency doubling crystal, the "green light problem", and the mode matching between the oscillating light in the resonator and the pumping light, which seriously affect the laser. Due to the problems of output power and its stability, light-to-light conversion efficiency and beam quality, a new laser diode-pumped high-power intracavity frequency-doubled laser is specially designed.
