Abstract

A two-mode laser with phase anisotropy can provide two linearly polarized and mutually orthogonal modes, which has various advantages over a one-mode laser. It is possible to produce a frequency-modulated signal in the recording channel with a modulation depth of about 100%, and also to vary the mode separation. Such lasers are used to measure the frequency response of photocells, as well as in plasma diagnosis, in quantum frequency standards, and for other purposes [1-3].
