Ultraviolet light has the advantages of large single photon energy, being easily focused, and most materials have strong absorption of ultraviolet light. It is widely used in marking, composite cutting, drilling, fine processing and other fields. An all-solid-state experimental device based on 1 064 nm infrared light and nonlinear optical frequency conversion technology to achieve 10 W 355 nm ultraviolet pulsed laser is reported in this paper. In the experiment, a “Z” type acousto-optic Q-switched 1 064 nm resonator, which is end-pumped by 888 nm semiconductor laser, was designed with a compact structure, stable power and good beam quality. The resonator has a large cavity mode, which can match the pump power well and alleviate the thermal effect of gain crystal. When the pump power is 85.7 W, the maximum average output power of 1 064 nm laser is 33.5 W, and its slope efficiency is 59.8% after linear fitting. The 355 nm ultraviolet laser is obtained by extra-cavity frequency doubling and extra-cavity frequency summing techniques. With the continuous increase of the incident pump power, in addition to the gradual increase of the powers of the 1 064 nm laser, 532 nm laser and 355 nm laser, the beam waist sizes and positions of the 1 064 nm laser and the 532 nm laser at the sum frequency crystal will have small changes, which will directly affect the output power and conversion efficiency of the 355 nm ultraviolet laser. When the incident pump power and repetition rate are 80 W and 50 kHz, respectively, a pulsed 355 nm ultraviolet laser with an average output power of 10 W, beam quality of M2x=1.12 and M2y=1.03 is obtained, and the conversion efficiency from the pump light to the ultraviolet light is 12.5%. It can be predicted that further optimizing the power ratio and beam waist size on this basis will result in a larger output power of 355 nm ultraviolet light.
