Abstract

Analyzed are different measurement methods of high quality optical cavity characteristics based on the many-beams interferometry effects. The discussion of the opportunity to make coefficients of total and diffraction cavity loss measurements, reflectivity measurements of low-loss highly reflecting mirror coatings and gain measurements of the active substance is given. The possibility to control of the resonance cavity spectrum, a level of selection, a quality of the mirrors alignment and an accuracy of the cavity monoblock making is discussed. Compared is the method based on the analysis of the cavity transmission spectrum and an alternative method based on the exponential decay time measurement. It is shown that examined methods are suitable for high quality cavity loss measurements although each of them has own peculiarity and own primary sphere of application. Each of them may be more or less of use for others enumerated laser parameters measurements.
