Abstract
High Intensity pulse laser is very important device as a light source of LIBS. For obtaining high peak power and short pulses, different approaches based on MOPA (Master Oscillator-Power Amplifier) scheme of master oscillator (MO) power amplifiers(PA) can be used. We use Stimulated Brillouin Scattering (SBS) cell in the power amplifier for laser pulse compression. Compression of pulses by SBS allows potentially receiving pulses by duration down to 100 picosecond and has following advantages. The compression of pulses at SBS have enough large power efficiency (usually more than 50%), that is much higher than power efficiency of extracting of a short pulse, from a long “train” of mode-locked pulses or cutting of short pulse from a long Q-switched pulse. As a results, pulse duration of the laser which we have developed is less than 300ps at 50mJ out-put energy. This means that intensity of the laser is 20 times higher than conventional Nd:YAG pulse lasers.
