Multistage stimulated-scattering compression of pulses from a YAG:Nd laser

Application of Nonlinear Light Scattering in Nanocarbon Suspensions for Adjustment of Laser Pulse Duration

“…The linear fit is seen to represent poorly the experimental data, whereas the quadratic relation provides a good fit to the data points. Formula (5), being in a qualitative agreement with the experimental data in Figure 3, is insufficient. This, in turn, suggests that the OL takes place not only due to the nonlinear scattering but also due to the nonlinear laser light absorption, which is left out of the account in (4).…”

Picosecond Raman compression laser at 1530 nm with aberration compensation

“…Later it was found that stimulated Brillouin scattering (SBS) may be suitable for pulse compression in multipass laser amplifiers [12]. Also, in the 1980s it was shown that lasers with a combination of Brillouin and Raman pulse compression are efficient for converting nanosecond pulses into a picosecond region [13]. Following the recent work, one-stage compression of a nanosecond pump into picosecond pulses is possible in counterpropagating pump beams with SRS [14] and SBS [15], but energetic efficiency and the possibilities of pump power scaling require additional investigations.…”

“…It is known [10,13] that the pulse compressor scheme should satisfy the following optimal conditions:…”
