Abstract
A comparative analysis of the parameters of picosecond laser pulses generat ed under conditions of pure passive mode-locking and passive negative feedb ack was made. A twofold pulse compression (from 31 to 13.9 ps) was obtained . For the case of generation of extended flattened pulse trains under condi tions of passive negative feedback, a considerable decrease in energy (from 24 to 5.7%) and time (from 20 to 3%) instabilities was achieved.
