Main features of this system are an adaptation a super stable single mode 500-picosecond pulsed Diode Pumped Solid State Lasers (DPSSL) with more than 8 kW peak power as a probe beam. Combining with high sensitive CCD camera it gives possibility to detect Raman spectra of different media at broad dynamic range of scattered light intensities from extremely week up to saturated signals. This Raman Spectrometer, equipped by confocal microscope could be used for Micro Raman 3D imaging
