Fiber Coupling Module Of The Beam Properties And Characterization

In recent years, large power semiconductor laser research and application of a rapid development trend, but because the semiconductor laser structure characteristics, the output beam divergence angle is large, the spot has larger ovality. Using optical method to solve this problem effectively, therefore, study of fiber coupling module beam characteristics measurement and characterization of the problem becomes very important.Papers from the laser beam quality of the laser beam quality characteristics, determinants, and the laser beam quality description method and the dissemination of representation theory, the laser beam from theoretic try to know. From a semiconductor laser and optical fiber coupling method based on semiconductor lasers, fiber coupling module of the beam characteristics of the improving condition of dependence, that semiconductor laser fiber coupling module of the beam quality improvement is based on semiconductor laser and fiber the coupling optical system of the decision, is affected by the semiconductor laser and optical fiber coupling efficiency Conclusion.In the experiment, the use of the beam profile and propagation measurement instrument on the actual semiconductor laser coupling module for coupling measurement, and the beam quality are analyzed and compared.
