Tunable pulse repetition-rate multiplication using phase-only line-by-line pulse shaping.
We demonstrate a method for all-optical, tunable pulse repetition-rate multiplication of a mode-locked laser based on spectral line-by-line control. In particular, two-to-five-times repetition-rate multiplication of a 9 GHz source is achieved with very high fidelity.
متن کاملGeneration of 20 GHz, sub-40 fs pulses at 960 nm via repetition-rate multiplication.
Optical filtering of a stabilized 1 GHz optical frequency comb produces a 20 GHz comb with approximately 40 nm bandwidth (FWHM) at 960 nm. Use of a low-finesse Fabry-Pérot cavity in a double-pass configuration provides a broad cavity coupling bandwidth (Deltalambda/lambda approximately 10%) and large suppression (50 dB) of unwanted modes. Pulse durations shorter than 40 fs with less than 2% res...
متن کاملSimultaneous repetition-rate multiplication and envelope control based on periodic phase- only and phase-mostly line-by-line pulse shaping
We experimentally demonstrate simultaneous pulse repetition-rate multiplication and periodic pulse-to-pulse peak-intensity control based on optimized periodic spectral line-by-line pulse shaping. Accordingly, the method allows us to generate multiplied pulse trains in which the amplitude of each single pulse in a period can be arbitrarily tailored. The technique is illustrated with the generati...
متن کاملPhase-coherent repetition rate multiplication of a mode-locked laser from 40 MHz to 1 GHz by injection locking.
We have used injection locking to multiply the repetition rate of a passively mode-locked femtosecond fiber laser from 40 MHz to 1 GHz while preserving optical phase coherence between the master laser and the slave output. The system is implemented almost completely in fiber and incorporates gain and passive saturable absorption. The slave repetition rate is set to a rational harmonic of the ma...
متن کاملOptical clock repetition-rate multiplier for high-speed digital optical logic circuits.
Repetition-rate multiplication has been shown by use of a fiber ring oscillator with a semiconductor optical amplifier as the gain medium and by use of fast saturation and recovery of the amplifier from an external optical pulse train. Repetition-frequency multiplication up to 6 times and up to 34.68-GHz frequency have been achieved.
