Abstract: An investigation was made of the conditions for optimisation of passive negative feedback with GaAs plates acting as feedback elements in picosecond pulse generation. A long (1 μs) train of pulses (τ = 13 ps) was generated in an Nd:YAG laser. A study was made of the influence of self-defocusing of picosecond pulses in the course of two-photon absorption in GaAs on the evolution of the time and energy parameters of the laser radiation.
