B&W Tek’s USB Raman excitation laser series is based on spectrum stabilization technologies and available at a low cost. The USB Cleanlaze products come in OEM and end-user packages, featuring narrow line width, 0.02 or 0.20 nm FWHM, from 25 mW to more than 1 W at 785 nm. The USB version allows for digitally dialing to an output power level to suit specific sampling needs, and the on/off digital laser control makes it convenient for background subtraction in Raman applications. Free space and fiber coupled versions are available.The BRM-785 Series Laser is a narrow spectral line width, high-power laser, specifically developed for the application of Raman spectroscopy. It is based on a novel light amplification and narrowing technology. It is compact and rugged, suitable for various industrial applications with an integrated laser driver, thermoelectric cooler, TEC controller and high-brightness fiber coupling.
