Abstract
The meter of average energy of holmium laser radiation is a digital measuring instrument, made on the basis of a pyroelectric detector and single-system microprocessor from the MCS- 51 family. This device enables a measurement of a defined number of light pulses, total energy of n-laser pulses as well as the number of pulses received by a detector. The frequency of sampling signal is 25 Hz, the accuracy of measurement is 5%. This meter also enables introducing the defined transmission coefficient (measurement at the back mirror of the laser resonator) to the measurement results as well as control of operation of the output diaphragm of the laser (TTL levels).
