METHOD FOR THE QUANTITATIVE DISPLAY OF VARIATIONS IN THE FREQUENCY OF LASERS WITH INTERIOR MIRROR IN TWO MODES, ESPECIALLY STABILIZED

摘要

P Method for the quantitative display of the frequency variations of lasers with two-mode interior mirror, specially stabilized, during a measurement operation, by application of the heterodyne optical measurement method, characterized in that for all laser tubes with set, the maximum voltage, established behind the I / U converter 9 during a change of mode, is brought to the same value, in that the voltage variation, occurring at measurement point 6, is brought to the same amplitude value, using the normalization amplifier 12, and in that the frequency variation of the laser light, corresponding to a determined voltage variation, measured at measurement point 7, is determined on a laser standard by the known heterodyne measurement method and the desired sensitivity for the variator 3 is then adjusted. /P
