Abstract

At present, we can observe progress in physics of crystalline Raman lasers leading to efficient nonlinear frequency conversion at transient regime for generation of ultra-short pulses of stimulated Raman scattering (SRS) radiation with picosecond duration and shorter [1,2]. Recently the problem of a femtosecond crystalline Raman laser with femtosecond pumping has been solved [1] using an efficient SRS in a Raman-active crystal (CVD-diamond) under synchronous pumping by repetitive femtosecond laser pulses in an external cavity with a round-trip time equal to the pump pulse repetition period. However, a challenge of femtosecond SRS pulse generation in crystals under pumping by picosecond lasers which is more simple, inexpensive, and prevalent in comparison with the unique femtosecond laser systems remained unsolved.
