A new device is developed for real-time monitoring of laser beam quality and adaptive collimating of laser beam direction. Based on lens imaging principle, the device is composed of one CCD camera for two-dimensional imaging of laser spot and two piezoelectrically drived mirrors to correct laser beam shift by the principle of two points exactly defining a line in space. The adaptive control is performed through a home-made computer program using Lab View software. The system can collimate the beam direction in a resolution of 0.5 μrad and 1 Hz adjusting frequency, and correct the laser spot shift of period above 1 s.
