Femtosecond diode laser MOPA system at 920 nm based on asymmetric colliding pulse mode-locking
2010
We report on the generation of 267 fs long pulses with a peak power of 661 W emitted by an InGaAs diode laser master-oscillator power-amplifier (MOPA) system with an external grating compressor. The oscillator emits strongly chirped picosecond pulses with several nanometer of bandwidth, which can be amplified without significant phase modulation and are compressed to femtosecond pulses after leaving the amplifier. We used a diode laser module for asymmetric colliding pulse mode-locking and optimized the collision point and the relative intensity of the counter-propagation pulses.
