摘要
Beam parameters of laser diode array (LDA) with an emitting area of 1μm×150 μm were measured by using the method suggested by ISO. The waist widths, divergences, waist positions, Rayleigh lengths and M2 factors of the LDA in x, y direction were determined. By using the micro-cylindrical lens as the fast axis collimator, the divergence of LDA was reduced to less than 1°. Optical system for coupling of LDA was designed, which yields coupling efficiency of 71.0 % and 83.4 % for 100 μm and 200μm fibers, respectively.
