We demonstrate wavelength conversion based on cross-phase modulation induced nonlinear polarization rotation in a carbon nanotubes-filled micro-slot fiber device. Wavelength converted signal with 3-dB power penalty for 10 Gb/s NRZ signal is obtained.
A Q-switched laser system which couples two ytterbium doped fibers is presented. Depending on the pump intensity this system yields either short or long nanosecond pulses. The gain competition accounts for the observed phenomena.
We experimentally investigate the interactions between solitons in multi-bound states generated from an active mode-locked fiber laser and within the ring cavity. Their phase difference and corresponding interactions between solitons are studied.
We evidenced the polarization rotation in an Yb3+ rod type fiber amplifier injected by a subnanosecond microlaser. Simple numerical simulations account for the observed phenomena.
Cavity dumping of a fiber laser is demonstrated. A microstructured fiber with an electrically driven internal electrode is used for intracavity polarization rotation with nanosecond risetime. The optical flux can be dumped within one roundtrip.
Record-short pulses of 200 fs have been obtained from a power-scalable-Yb-fiber-CPA system that uses chirped-volume-Bragg-gratings for the stretcher and compressor. The power was scaled up to 50 W with a corresponding 33 W of compressed power.
A long ring-cavity, low repetition rate Yb-doped fiber laser was demonstrated. Pulses with repetition rate of about 381.3 kHz and single pulse energy above 300 nJ were obtained.
