Abstract

In development of a known method of an regenerative amplification of low-power picosecond pulses (the injection seeding method) its modification: the method of injection locking of master laser with the amplifying laser (laser with short-term resonance modulation of losses--STRML-laser) is offered. The use of the STRML-laser as the regenerative amplifier allows to lower a level of the laser-injector power on two-four order. For the neodymium laser with an output pulse energy 1 - 2 J this power can be lowered up to 1 W, and the reliable capture can be carried out with 5 W. It enables to realize the circuit of self-injection in the STRML-laser by adding a nonlinear passive modulator in a cavity. Thus at a beginning of linear stage it is possible to `sow' pulses resulting in generation of much more short on a comparison with realized in a STRML-regime with preservation of remaining positive qualities of this laser.
