Abstract Pumped by a frequency-doubled Nd:YAG laser, 10-Hz repetition rate, 320-mJ pump energy, and 5.1-ns pulse width, a liquid Raman laser using acetone as the Raman shifting medium has been established. The residual pump laser pulse and the generated Stokes pulse are directed to a DCM dye cell for energy enhancement of the Stokes pulse. The Raman laser system is capable to produce a laser pulse at wavelength 630nm, with single pulse energy of 120mJ, peak power of 70MW and an average power of 1200mW. The energy conversion efficiency is 37.5%, or equivalently a quantum efficiency of 44.5%.
