Abstract
The laser comprises an amplifying medium which sustains the oscillation within two resonators, one resonator being formed by the mirrors M.sub.1 and M'.sub.1 and the other being formed by the mirrors M.sub.2 and M'.sub.2. The quality factor of the second resonator is higher than that of the first resonator. The time-duration of the pulse extracted from the first resonator is adjusted by modifying the quality factor of the second resonator. The double-resonator laser serves to generate pulses of very small width, especially in dye lasers, and to adjust pulse-widths in such applications as telemetry.
