New instrument for metrology applications in measurements of laser pulse energy is presented. Due to its parameters it can be used as a standard for unit of energy of pulse laser radiation. The instrument consists of a control unit, three different sources of laser radiation, two receivers of optical signal, and a laptop. The whole system can be easily transported enabling one to carry out measurements in situ, at customers, not only in laboratory conditions. A method of measurement used in operation of the standard is described. Main characteristics of the standard are shown. Methods of calculation of uncertainties of measurement during laser energy meters calibration by means of our standard are also presented.

When macrobodies undergo collision, macrocraters are formed for which the ratio of crater's depth to striker diameter does not exceed 10. At the end of the 70's, an anomalous effect of formation of microcraters with relative depth of about [10^2-10^4] of particle size has been detected. Analysis of the experimental results made it possible to reveal the existence of a narrow impact interaction zone within which craters-channels are produced with a good repeatability. Evidence of a limited relative depth under macroimpact is explained by restrictions imposed by energy intensity of impact interaction in a barrier material.
