CONTROLLABLE MICHELSON INTERFEROMETER OF REFRACTIVE TYPE

In some applications of a Michelson interferometer, in particular, when it is used in a laser resonator, the high stability of its phases is necessary. The proposed paper contains the comparison of two interferometer configurations. The first of them uses a classical schematic interferometer, the second one is designed with the use of a refractive schematic one, which is typical of enhanced stability against misalignments and occasional fluctuations of surrounding air. The possibility is discussed of applying the controllable refractive interferometer inside the resonator for generation of ultra short laser pulses.
