Coherent light self-modulation process was studied by modeling the running wave interferometers scheme containing
beam splitting, delaying and amplifying. Principal possibilities of cw laser light modulation with GHz - THz frequencies
and amplified pulses formation by cw pumping are shown. Some scheme parameters and input light features influences
on said processes are illustrated and discussed. Pulse transformation in running wave interferometers (with and without
amplification) was also studied by computer modeling. Pulse compression along with pulse form changes and specific
pulsing generation with cw pump were found.
Some possibilities of simple and thus reliable schemes of experiment "self-control" exploiting intrinsic features of studied non-linear phenomena like wave front reversal under stimulated Brillouin scattering (SBS), stimulated Raman scattering (SRS) and coherent anti-Stokes Raman scattering (CARS) rather than outer sensors and controls are described. The schemes discussed provide input signal dynamic region broadening in stimulated scattering converters and angle of synchronism self-tuning while two frequency pumping.
