- Abstract
This paper shows that significant energy losses in the Q-switched lasers are due to enhanced luminescence. We experimentally confirm the reduction of the relaxation time of the active centers with a high level of population inversion working levels. We propose a method of reducing losses of luminescence enhancement by using "complex" pump pulses. We analyze the use of "double" and "complex" pump pulses. Excitation of "double" pump pulse can reduce the loss by 7-10 %. "Complex" pump pulse provides the increased energy output by more than 20 % compared to "smooth" pump pulse with the same energy. We demonstrate that the increase of energy efficiency of energy conversion in a 'complex' pumping is accompanied by increased stability of output power. Nevertheless, this method is not trivial and requires a lot of correlation spikes of short follow-up period with crystals geometrical dimensions. The proposed method of laser excitation can be successfully used in monopulse laser-radar transmitters stations and remote sensing systems.
