Paper Abstract

The experimental substantiation of the theoretical thesis, that excitation of the laser radiation fluctuations, due to instability of an electrooptical feedback circuit, occurs on intermodal (roundtrip) frequencies, established earlier, is received, i.e. accompanied by transition of the laser generation in a synchronized modes regime. This is the synchronization modes of active type because electrooptical Pockels lock was used for the generation handling in the experiment. It became easily to obtain such phenomenon due to use of a broadband feedback circuit which is formed by a broadband photodetector and specially designed for a feedback circuit broadband amplifier. It is shown, that for effective transition to a synchronized modes regime with the attraction of the non-linear filters is also necessary. Reduced train of ultrashort pulses received for a case of positive feedback allows to hope, that effective lengthening will be possible in a case of negative feedback that is important for medical applications, for example.
