ИСТИНА

In this paper, we consider schematic solutions maintaining development of such kind of energy-effective, compact, robust and easy integrable picoseconds lasers based on Nd-doped crystals. We develop approach based on the dynamical operation control scheme utilizing pulsed repetitive pumping, active and passive mode-locking, negative feedback, adjustable loss level in the oscillator cavity and switching regenerative amplification regime. This provides laser pulse formation in each laser shot and actually allows shortest way for obtaining just at the laser output near transform limited picosecond pulses of several millijoules energy with excellent pulse-to-pulse stability and low optical jitter value. Both oscillator and regenerative amplifier can be based on the same single active crystal.
