Abstract
For efficient operation of lidar systems, highly coherent radiation with a capability of smooth wavelength tuning in a given spectral range is required. This paper presents the results of experimental studies of an alexandrite laser on the generation of coherent radiation in a compound dispersion cavity with various spectral and spatial selectors located in the external and main cavities, respectively. The mode structure of the output radiation is studied depending on the selective properties of the cavity used. The operating conditions of the compound cavity necessary for the generation of narrow-band tunable radiation in the self-injection mode are considered.
