Abstract
The possibility of soliton self-compression of ultrashort laser pulses down to the few-cycle regime in photonic crystal fibers is numerically investigated. We show that efficient sub-two-cycle temporal compression of nanojoule-level pulses can be achieved by employing short (typically long) commercially available photonic crystal fibers and pulse durations of around , regardless of initial linear chirp, and without the need of additional dispersion compensation techniques. We envision applications in a new generation of compact and efficient sub-two cycle laser pulse sources.
