A new laser beam collimation method that combines fiber collimation technique with laser beam drift feedback controll is investigated. In this method, the laser beam drift is initially collimated by passing though a single-mode fiber, then it is collimated further by a feedback control system for the purpose of improving the direction stabilization of the laser beam. In this feedback system, the displacement drift and angle drift are not only measured respectively using a drift separation optical system and a drift photoelectric measurement system, but also each of them has a corresponding independent feedback control system to restrain itself, at the same time the coupling between them is decreased. Due to the single-mode fiber is used, the laser system is far from the beam drift feedback control system. So the temperature effect from the laser source on the collimation system is decreased and the collimation system can be easily arranged. By applying these techniques, the collimation precision and efficiency are improved and experimental results show the collimation precision for the laser beam drift can reach 0.7×10-7 rad.
