Intelligent test system for performance parameter of laser

To solve the problems existing in the present test system such as low testing precision and simple function, a new intelligent test system is developed, which involves control technology, quick and convenient WIN32 computer software and a special beam splitter system. It can simultaneously measure optical axis parallelism, width and energy of the pulse, beam divergence, beam axis stability, and system performance. A high-powered infrared autocollimator is adopted to ensure 2″ of spatial resolution, a 15GHz oscilloscope is used to capture the laser pulse as narrow as 100ps, and an accurate laser power meter with large dynamic range is used to obtain accurate energy measurement of the laser pulse. The system is checked and accepted, and all the performance parameters meet the design requirements.
