Description/Abstract

Passively mode-locked fibre Soliton Lasers (PSL) have recently become of considerable interest owing to their ability to produce ultrashort pulses in a simple laser cavity configuration. In addition, a lot of interesting effects are involved in the PSL operation. The mode-locking process in PSL is similar to that of a laser with a fast saturable absorber and is initiated by the most intensive fluctuation of the intracavity energy flow. Another important feature of PSL is the soliton nature of the generated pulses resulting in a well-defined energy of an individual pulse. Typically, PSL generates a few pulses per round-trip period, and the time interval between pulses is a random value as there is no force holding pulses at certain time distance. Nevertheless, under certain circumstancies, the laser output pattern demonstrates stability during several minutes. Thus, the study of the possibility to initiate mode-locking process by a regular external signal and to generate sequences of pulses predetermined by this signal is of considerable importance.
