Paper Abstract

In order to meet some fields' need for the laser beam of variable divergence angle, a divergence angle program control system was designed in this paper. The system realized the automatic control, based on "computer + stepping motor+ the collimation system". It consisted of a collimation system, a control software unit, a hardware unit and the detection unit. In the collimation system, the relationship between the output beam divergence angle and the distance between the two lenses was found by theoretical analysis. Then the output beam divergence angle could be controlled precisely when the distance was altered precisely by stepping motor. Experiment was carried out to validate feasibility of the design. The result showed that the design was effective and it was easy and fast to alter control beam divergence angle, based on the design.
