PASSIVE STABILISATION OF MICHELSON INTERFEROMETER

In some applications of a Michelson interferometer, in particular, when it is used in a laser resonator, the phase difference of radiation beams passing the interferometer optical branches must be stabilized with high accuracy. The proposed paper is devoted to experimental studying the long-term stability of several interferometer designs and choosing the optimal version for applying as a compound resonator mirror with the controllable reflection for generation of ultrashort laser pulses.
