METHOD OF GENERATING LASER RADIATION OF REFERENCE POWER Russian patent published in 2019 - IPC G01J1/04 H01S3/13 

FIELD: physics.

SUBSTANCE: invention relates to energy photometry and a method of generating laser radiation of reference power. Method includes attenuation of power of laser radiation from selected source by means of main rotating mechanical attenuator from absorbing material with angular cut, measurement of obtained power P_e using reference receiver, calculation of reference power P_m laser radiation and generation of laser radiation of reference power P_m. When generating laser radiation of reference power, an auxiliary rotary mechanical attenuator in the form of an angular fragment which repeats the above angular cut is used. Reference power of generated laser radiation is calculated as P_m=P_e⋅K_o/K_a, where K_o is the attenuation factor of the main attenuator, and K_a – auxiliary.

EFFECT: technical result consists in improvement of accuracy of reproduction of reference power.
