External cavity enhancement of picosecond pulses with 28,000 cavity finesse

External cavity enhancement of ps pulses with 28 000 cavity finesse

We report on the first demonstration of the locking of a Fabry-Perot cavity with finesse 28 000 in the pulsed regime. The system is based on a stable picosecond oscillator, an ultra stable cavity with high reflection mirrors and an all-numerical feedback system that allows efficient and independent control of the repetition rate and the carrier envelop phase drift. We show that the carrier to e...

Picosecond-pulse amplification with an external passive optical cavity.

We experimentally demonstrate the amplification of picosecond pulses at high repetition rates through the coherent addition of successive pulses of a mode-locked pulse train in a high-finesse optical cavity equipped with cavity dumping. Amplification greater than 30 times is obtained at a repetition rate of 253 kHz, boosting the 5.3-nJ pulses from a commercial mode-locked picosecond Ti:sapphire...

Modulation enhancement of a laser diode in an external cavity

We present experimental results demonstrating enhanced current modulation of an antireflection-coated edge-emitting laser diode placed in an external cavity. By eliminating the internal cavity of the laser diode and matching the external cavity free spectral range to the modulation frequency we have increased the modulation response up to nearly complete carrier suppression. We demonstrate the ...
