چکیده
We report soliton pulse formation and amplification and soliton-self-frequency shifting in an anomalously dispersive, Yb31-doped holey fiber amplifier seeded with pulses from an Yb31-doped, 1.06-mm fiber based modelocked oscillator. Our fiber-based system provides a highly practical, all-diode-pumped, continuously tunable femtosecond pulse source operational in the important and difficult to reach wavelength range from 1.06 to 1.33 mm. In other experiments multipulse, multicolored soliton formation was observed with wavelengthshifted pulsed output to beyond 1.58 mm. Supercontinuum generation and nonlinear compression of pulses to 65 fs were also obtained with other configurations. © 2002 Optical Society of America OCIS codes: 060.2320, 060.4370, 190.2640, 190.5650, 999.9999.

Compact Tunable 10 W picosecond Sourcebased on Yb-doped Fiber Amplification of Gain Switch Laser Diode
A compact tunable 10 W picosecond source based on Yb-doped fiber amplification of gain switch laser diode has been demonstrated. A gain switch semiconductor laser diode was used as the seed source, and a multi-stage single mode Yb-doped fiber preamplifier was combined with two large mode area double-clad Yb-doped fiber main amplifiers to construct the amplification system. The tunable pulses wi...
متن کاملBroadly tunable carrier envelope phase stable optical parametric amplifier pumped by a monolithic ytterbium fiber amplifier.
In an effort to develop a robust and efficient front end for a chirped-pulse parametric amplification chain, we demonstrate a broadband difference-frequency converter driven by a monolithic femtosecond Yb-doped-fiber amplifier and emitting carrier-envelope-offset-free pulses with the energy of tens of nanojoules tunable in the wavelength range from 1200 nm to beyond 2 mum. Next to providing the...
متن کاملSoliton transmission and supercontinuum generation in holey fiber, using a diode pumped Ytterbium fiber source.
We report linear dispersion compensation, soliton pulse formation, soliton compression, and ultra-broad supercontinuum generation in a holey fiber with anomalous dispersion at wavelengths above 800nm. The holey fiber was seeded with ultrashort pulses from a diode pumped, Ytterbium (Yb)-doped fiber source operating at 1.06 microm. The results highlight the compatibility of the rapidly developing...

By seeding stretched pulses from a femtosecond Yb fiber oscillator into a cryogenically cooled DPSS regenerative amplifier based on a novel Na-co-doped Yb:CaF2 laser crystal, we obtain >3-mJ pulses at a 1-kHz repetition rate with a spectral bandwidth exceeding 12 nm. The pulses are compressed with a single grating compressor to 173 fs as verified by SHG FROG. Shaping of the spectral amplitude o...
متن کاملAll-Fiber Bismuth Doped Self-Sweeping Laser
Figure 1: Laser wavelength dynamics The effect of self-induced laser line sweeping (or self-sweeping) was discovered in ruby laser in 1962 [1]. It was considered as an undesirable effect due to a small sweeping range. In fiber lasers the effect with broad sweeping range (more than 10 nm) was observed almost 50 years later [2]. The self-sweeping effect is caused by the formation of dynamical pha...
