Generation of picosecond impulses by dye laser with distributed feedback

The influence of amplitude and phase lattices on kinetics generated by dye lasers with distributed feedback radiation is delimited in the present paper. It is shown that generation regime of single impulses of 200 ps is realized when amplitude lattice plays the major role in the feedback and in the case of little above threshold of pumping. In the case of primary contribution to the feedback of thermal phase lattice the nonstructural impulse of nanosecond duration is generated.
