Based on laser power meter calibration requirements, through the purchase of standard equipment and field monitoring equipment developed, standard laser detector, optical path related equipment, such as construction of laser radiation power meter calibration test system, implementation of laser power meter of laboratory test and vehicle, large equipment form a complete set of laser power meter field test and field test of the radiated power of the laser equipment. Calibration system is introduced in detail the composition and working principle of the uncertainty of the system are analysed in detail, and through the system stability test, laser power, beam monitoring and correction device performance test, ate test for power meter calibration experiment data analysis, proved in this study, the laser power meter calibration method provided will enable calibration system, the expanded uncertainty of relative reached 2% ( k = 2), which can realise wavelength of 532 and 1064 nm, power measuring the range of 0.1 mW–20 W laser power meter calibration.
