35 GHz passive mode-locking of InGaAs/GaAs quantum dot lasers at 1.3 μm with Fourier-limited pulses

We report 35 GHz passive mode-locking and 20 GHz hybrid mode-locking of quantum dot (QD) lasers at 1.3 μm. Our investigations show ultrafast absorber recovery times and for the first time transform-limited mode-locked pulses. © 2003 Optical Society of America.

Passive mode-locking of bow-tie lasers

The passive mode-locking in novel double tapered Bow-Tie lasers is investigated. This investigation aims to determine the possible GHz repetition rate at which passive mode-locking is derived, in addition, the record power levels will also be demonstrated. Alternative drive schemes and contact configurations to achieve optimized performance are discussed.

Mode-locking by nanotubes of a Raman laser based on a highly doped GeO 2 fiber

A mode-locked Raman laser, using 25 m of a GeO2 doped fiber as the gain medium, is reported employing carbon nanotubes. The oscillator generates 850 ps chirped pulses, which are externally compressed to 185 ps. © 2012 OSA.
