By combining a passively mode-locked high-power laser with a large mode area holey fiber for nonlinear compression, we generated 33-fs pulses with 18-W average power. The output beam is linearly polarized and close to diffraction-limited.

We demonstrate the first 10Gb/s DWDM transmission at 12.5GHz spacing without polarization division multiplexing or polarization interleaving. This dense channel spacing is accomplished via vestigial sideband filtering and 8x10Gb/s has been transmitted over 100km of SMF without repeaters.

Amplification of ultrashort laser pulses is demonstrated in a gas medium of the photolytical XeF(C–A) laser. A gas mixture of XeF2:N2:Ar was excited by vacuum-ultraviolet radiation produced by a high-current multichannel sliding discharge, which was initiated along one side of dielectric laser cavity. A small-signal gain of 1.6×10−3 cm−1 is observed for a seed pulse at 488 nm with ∼150 fs duration. The use of a second optical source together with the device optimization promise a multiple increase in the gain and the obtaining of high-contrast TW femtosecond pulses as a result of direct amplification, without application of a stretching/compression technique.

A frequency-domain description of the dynamics of the multimode laser incorporating intra-cavity nonlinear elements for both mode-locking and frequency conversion has been developed. Numerical results show that nonlinear elements can drastically affect the dynamics of mode-locking.

Laser emission at about 3.5 THz from quantum cascade lasers based on a bound-to-continuum transition is reported. Maximum pulsed operation temperature is above liquid nitrogen (90 K). CW operation reaches 55 K with powers up to 15 mW at 10 K.
