Laser Diode

CNI provides laser diodes with free space and fiber coupling option from 405-1550 nm wavelength range. The free space laser diode can be divided in to single mode and multimode. The fiber coupled laser diode can be divided into SM, PM, MM pigtailed and high power laser diode module. The small emitting aperture, combined with low beam divergence, make these devices the highest-brightness family of CW laser diodes available in the industry.
