Determination of the Peak Power of Monopulses of YAG:Nd3+ Laser Emission

The results of determination of the peak power of monopulses of YAG:Nd(3+ )laser emission by two methods are presented. It is shown that the most reliable data can be obtained by the procedure from GOST and by the often used method when recording the time form of the monopulse of radiation using an FK-15 coaxial photocell. An often used technique using the measured value of the monopulse duration by the level of 0.5 of the amplitude value, when recording the time shape using an LFD-2 avalanche photodiode overestimates the value of the peak power of the monopulse compared to a reliable one by 12%.
