Changchun New Industries Optoelectronics Technology Co., Ltd.
CNI provides laser diode 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.
CNI can supply specialty optical fiber for laser coupling. Our products include single-mode fiber, multi-mode fiber, polarization maintaining fiber, liquid light fiber and fiber with pigtailed GRIN lens collimators for all our existing laser modules from visible to near IR transmission.
A beam expander is any optical system designed to increase the diameter of a laser beam. In most cases, the term is taken to mean a telescope designed to take a small-diameter collimated beam input beam and produce a larger diameter collimated output beam, thus reducing the divergence of the beam. The beam expander consists of a negative input lens and a positive objective. The expansion factor is the ratio of the focal length of the two lenses.
Coated Laser Crystal
CNI is capable of supplying a large quantity of laser crystals with high damage coatings to meet the tough requirement from both the OEM and R&D customers.
