Abstract

Good directivity produces laser a promising applying prospects. For the characteristic of laser itself and the environmental effects, there are drifts in laser beam with random quantity and direction. In the cases of some very high accuracy, especially in laser directivity and laser alignment, the error caused by drift is unneglected. So it is necessary to measure the drift of laser beam with high accuracy.
