OPTICAL SYSTEM AND METHOD FOR PULSE REPETITION RATE MULTIPLICATION OF A LASER SOURCE

摘要

Disclosed herein is an optical system and method for improved pulse repetition rate multiplication of a pulsed laser source using a master and slave resonator, where the slave repetition rate is set to a rational harmonic of the master repetition rate. The optical system comprises an optical source (master) arranged to generate optical pulses, an optical resonator (slave) having an optical input arranged for receiving the optical pulses, and also having an optical output. The optical resonator also contains a saturable absorber and gain medium. The system can furthermore comprise an active frequency modulating element.
