A method is proposed for active stabilization of the ruby-laser frequency. The gist of the method is that the Q of the laser resonator is chosen to be low enough to make the lasing frequency and its stability governed by a high-Q Fabry--Perot interferometer placed inside the resonator at a small angle to its axis. The distance between the interferometer mirror is rigidly stabilized with the aid of an electron-optical negative-feedback system that consists of a stabilized He-Ne laser, a photoreceiver, and a differential amplifier. The absolute instability of the frequency amounts to 3times10$sup -3$ cm$sup -1$. (AIP)
