Ultraviolet lasers with picosecond pulse widths can quickly break the molecular bonds of materials, reducing interaction time. At the same time, they have high temporal resolution. In order to obtain an ultraviolet laser with a picosecond pulse width, a solid fiber, hybrid-amplified 213 nm laser was designed. First, a 1 064 nm fiber laser with a repetition rate of 5 MHz, pulse width of 52 ps, and average power of 2.5 W was used as a seed source. After two stages of end pumped Nd∶YVO4 crystal amplification, a 1 064 nm laser with an average power of 10.5 W was obtained.This 1 064 nm laser and a 266 nm laser were then combined in a BBO crystal to produce a 213 nm UV laser.The final output is a 213 nm UV laser with a pulse width of 690 ps and an average power of 61 mW. The nonlinear conversion efficiency is 0.58%.
