“…It is much longer than for the Q-switching laser, agrees to fluctuation representations about dynamics of an establishment of generation in the STRML-laser [6]. Due to existence of a delay in forming of own pulse of the amplifying laser generation the injected USP at once begins to amplify intensively, essentially anticipating the natural increase ofthe luminescence field component.…”

“…The capture conditions in an injection seeding regime can be determined from positions ofthe fluctuation theory of USP forming at large exceeding by an amplification of a generation threshold similarly [6] for the laser with short-term resonance modulation of losses (STRML). According to this approach the USP forming in the beginning of a linear stage begins with one or several maximum (in the range of defmed temporal sample) fluctuation field spike of a spontaneous radiation, Then the capture in the injection amplification methods can be presented as an result of a competition in forming between maximum fluctuation spike ofa spontaneous radiation and injected USP from the outside.…”

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 (IL) 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 ofthe laser -injector power on two -fourorder. 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 5W. 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 ofremaining positive qualities ofthis laser.On experimental established optical properties of a passive modulator on base of computer model of the STRMLlaser checked earlier by physical experiments a reality of a realization of this circuit numerically is confirmed. The experiments with film modulator convince of a possibility of a regenerative amplification of the picosecond ultra-short pulses (USP) in itself laser up to greatest possible (from reasons of optical durability) energies.
