Abstract

Abstract: The hybrid laser system based on the picosecond fiber ring laser with a two fiber preamplifiers and terminal bulk amplifier was demonstrated. The cavity length of the master oscillator was 200 meters, the mode-locking regime was realized by the effect of nonlinear polarization evolution. After amplification and conversion of radiation to the second harmonic while using the lithium niobate crystal, the laser system emitted bursts of pulses at a wavelength of 539.5 nm with a duration of 70 μ s at the half of maximum. The energy in a single pulse with a duration of 100 ps was up to 270 μ J and short pulses repetition rate inside bursts was 1 MHz.
