THE COMPETITION OF SPECTRAL COMPONENTS OF A TUNABLE LASER UNDER THE BIHARMONIC EXCITATION OF AN ACOUSTOOPTIC DEFLECTOR

Relationships have been studied of formation of a multifrequency radiation spectrum in a laser with electronic tuning by an acoustooptic deflector. A model has been suggested and substantiated which takes into account both the competition of spectral components in the active medium and redistribution of their energies by two sonic waves associated with the absence of selection in the deflector. A mechanism is revealed which is responsible for essential difference between energy efficiencies of the fundamental optical laser components and an additional component which arises therewith. This mechanism governs peculiar features of the three-frequency stimulated emission. An influence has been studied of sonic wave parameters on spectral characteristics which made it possible to substantiate several laser control algorithms.
