Title

Nonlinear compression of Q-Switched laser pulses to the realm of ultrashort durations

Abstract
Mode-locked lasers have an undisputed position in the ultrafast domain, though they are fairly expensive for miscellaneous applications. Thus, laser consumers revert to more cost-effective systems like Q-switched lasers. Here we report on the nonlinear compression of passively Q-switched laser pulses that allows accessing the time domain of sub-10-picoseconds, which has been so far the realm of mode-locked lasers. Laser pulses with an initial duration of 100ps from a passively Q-switched microchip laser are amplified in a photonic crystal fiber and spectrally broadened from 20pm to 0.68nm by self-phase modulation. These pulses are compressed in a grating compressor to a duration of 6ps with a pulse energy of 13µJ.
