| 摘要 |
The invention relates to a gas laser assembly which is capable of emitting stabilized frequency pulse radiation. Said arrangement includes a first continuous gas laser generator and a second pulse gas laser generator, an optical system (19, 56, 20) to inject the continuous beam (18) emitted by the first laser generator via the optical cavity (8-9) of the second laser generator and a servo control circuit (21,23,24,25) acting in synchronism on the length of the cavities (5-6,8-9) of the first and second lasers, so as to keep these lengths equal at a fixed value. Application to range finders operating by heterodyne detection. |
