In recent years, with the rapid development of high-intensity picosecond lasers, it has prompted renewed interest in techniques of nonlinear frequency conversion of ultra-short pulses. As we know, it's not easy to directly generate picosecond laser sources in the UV and near-visible region, which has many applications in the field of micro-manufacturing and remote sensing of the environment. One attractive way to acquiring a desired wavelength is through the nonlinear frequency conversion, stimulated raman scattering(SRS). In this paper, with a 10HZ 10mJ high intensity picosecond 532nm laser source, we try to get high efficiency, coherent UV picoscond laser simultaneously at several wavelengths.
