What are the advantages of fiber coupled output semiconductor lasers?
The laser beam directly output by the semiconductor laser light-emitting unit is an elliptical asymmetric Gaussian beam, which has a large divergence angle and extremely uneven spot. In some application fields, it must be shaped and spot uniformized. There are two commonly used shaping methods: optical lens shaping and fiber coupling shaping. Simple optical lens shaping can compress the beam into a rectangle, but the spot uniformity is poor and it is not flexible to use. Through fiber coupling, the optical spot output by the fiber is a circular symmetrical spot with good uniformity, and the beam quality is improved. At the same time, fiber coupling is an important means to achieve flexible laser transmission, which greatly enhances the flexibility and operability of semiconductor lasers. It is more flexible and convenient to use in medical, processing and other fields. Box Optronics focuses on fiber coupling and mainly provides fiber coupled semiconductor lasers.
