Embedded integrated laser parameter self-diagnosis system and workflow thereof

Abstract

The invention, which relates to the field of laser diagnosis, discloses an embedded integrated laser parameter self-diagnosis system and a workflow thereof, thereby solving problems of the existing laser diagnostic equipment. The system comprises a cavity provided with an incident window. A charge coupled device, a first attenuating piece, a third reflecting mirror, a second reflecting mirror, a convex lens, a saturable absorber, a first photodiode, a first reflecting mirror, a second photodiode, a four-quadrant detector, and a second attenuating piece are installed in the cavity. The disclosed system has high integration; a special-purpose measuring optical path, a special-purpose measuring instrument, a special-purpose measuring and controlling circuit and special-purpose input / output interfaces are arranged in the system; and the system has the function of connection and integration with a to-be-measured laser. The system has characteristics of real-time measurement, fast measurement, simultaneous measurement of multiple parameters, and unified data collection and has high capabilities of automatically complete measurement and diagnosis and outputting the diagnostic result; thelaser can carry out measurement by itself and various optical parameter indicators can be determined; and online automatic closed-loop monitoring can be completed.

Description

technical field [0001] The invention relates to the field of laser diagnosis, in particular to an embedded laser parameter comprehensive self-diagnosis system. Background technique [0002] As an artificial high-brightness and high-coherence light source, lasers have been widely used in scientific research, industrial production, medical treatment, national defense and many other fields. Depending on the application, the requirements for the optical parameters of the laser are also different. The parameters for evaluating the basic performance of lasers include average power, wavelength, energy, beam quality, pulse repetition frequency, pulse width, degree of polarization, etc. The practical value of a laser is determined by the comprehensive performance of these parameters, and a single parameter is highlighted It cannot meet the requirements of practical application. For example, for industrial processing applications, the intensity characteristics and spatial distributio...
