Description
A SWAP (Size, Weight, and Power) - compatible laser source for portable and industrial Raman spectroscopy!
Up to 1W of spectrally-stabilized laser radiation, an integrated clean-up filter, and a robust package (much more robust than butterfly packages) - the features all laser integrators have asked for - are now available in the new 'Samogitian' laser platform.
An OEM-dedicated package comprises no driving electronics, just a powerful laser diode (multimode beam), collimation, and wavelength stabilization optics.
Filter - Clean-up filter (CF):
It is used to increase side-mode suppression ratio (SMSR) in SLM laser and eliminate spontaneous emission of a laser diode.
