Burst mode dye laser with high pulse energy at 10 kHz repetition rate

In this paper, we present a dye laser operated under burst mode with minimum pulse interval 0.1 ms, corresponding to repetition rate 10 kHz. Pulse energy of 7.77 mJ with efficiency of 26.7% is achieved at 560 nm by using rhodamine 6G solution in methanol as the gain medium when the energy of pump energy is 32.4 mJ at 532 nm. The tunable range is found from 545.3 nm to 573.1 nm for fundamental and 272.5 nm to 286.9 nm after frequency doubling with maximum pulse energy 1.45 mJ at 280 nm, which indicates the frequency doubling efficiency is 18.7%. OH-PLIF images with time interval 0.1 ms are gotten using the dye laser, which proves the feasibility of this dye laser applied in dynamic laser diagnosis fields.
