摘要：

The results of optimisation of active and passive negative feedback (NF) for generation of stable compressed picosecond pulse trains in Nd:glass and Nd:YAG lasers using a modulator driven by fast photomultiplier and a GaAs passive element are presented, Conditions of prolonged pulse trains generation with the duration of trains varied from 0.3 mu s to 200 mu s depending on parameters of active NF were investigated. Generation of long (1000 ns) pulse trains in passive NF regime was obtained. Pulse compression in active and passive NF regimes (from 8 ps to 1.4 ps and from 35 ps to 13 ps, respectively) was achieved.
