ON THE POSSIBILITY OF GENERATION OF ULTRASHORT PULSES IN SHORT-GAIN-DURATION LASERS BY FAST MODE-LOCKING USING AN ELECTROOPTIC DEFLECTOR

Fast mode locking with the use of an electro-optic deflector-a novel m ethod for production of ultrashort pulses (USPs) in short-gain-duratio n lasers-is briefly described and discussed. The potential of this met hod is demonstrated by using numerical simulation of USP generation ta king a KrF laser as an example. It is shown that pulses of several pic oseconds in duration can be produced with this method at a gain durati on of only 50 ns, i.e. the pulses can be two orders of magnitude short er than those attainable with conventional mode locking. Some properti es of USP generation with the use of an electro-optic deflector are de scribed.
