Paper Abstract

The design of laser beam performance test system is a technique consists of optics, mechanism, electricity, computer and so on. The design and measure methods of the laser beam performance test system in this paper are according to the ISO laser and laser-related equipment international standard (ISO 1146). This test system consists of laser energy meter, oscilloscope, high speed photoelectric detector, CCD, laser attenuator, neutral attenuator, PCI image grabbing card, focal optical system, beam analysis process software and so on. The laser beam performance parameters tested by the system include spatial characteristic parameters, temporal characteristic parameters, laser output energy and so on. Spatial characteristic parameters include beam spot two-dimensional distribution, light-intensity three-dimensional distribution, beam divergence angle, beam direction stability and so on. Temporal characteristic parameters include laser pulse width and repetition frequency. At last a laser was tested and the result was satisfied.
