Modification LCM-S-111-20-R has been specially developed for Raman spectroscopy. Due to a special technical solution, back reflection hitting output laser aperture does not have an essential influence on the output power stability and the level of optical noise. This advantage makes the laser an ideal source for use in Raman spectroscopy.
