  • To quantitative research the micro-collimator position on the influence of divergence Angle of high-power diode laser array, light transmission matrix and CCD imaging method were used to measure the beam pointing and divergence angle of collimated diode laser array. Compared with far-field characteristics of diode laser analyzer measure the residual divergence angle, it can be know that the position adjustment of collimator can be monitored effectively by CCD imaging method, and the deviation of divergence angle can be controlled within 13%. Meanwhile, to optimize algorithm and provide experiment basis in fully automatic assemble fast axis collimation, the influences of the six degrees of freedom on the positional deviation of fast axis collimation on the divergence angle were tested, and the tolerance value of each axis for collimator was analysized.Resultsshow that the required solution of each axis are different for assembling fast axis collimator, and the y axis requires the highest solution.
