C. Y. Wang,Lyuba Kuznetsova,Vasileios-Marios Gkortsas,Laurent Diehl,Franz X. Kärtner,Mikhail A. Belkin,Alexey Belyanin,Xiaofeng Li,Donhee Ham,Harald Schneider,P. D. Grant,C. Y. Song,Soufien Haffouz,Z. R. Wasilewski,H. C. Liu,Federico Capasso +15 more
TL;DR: This study reports the unequivocal demonstration of midinfrared mode-locked pulses from quantum cascade lasers generated by actively modulating the current and hence the gain of an edge-emitting quantum cascade laser (QCL).
Journal ArticleDOI
Compensation of nonlinear phase shifts with third-order dispersion in short-pulse fiber amplifiers
TL;DR: It is shown that nonlinear phase shifts and third-order dispersion can compensate each other in short-pulse fiber amplifiers, and contrary to common belief, fiber stretchers can perform as well or better than grating stretchers in fiber amplifier, while offering the major practical advantages of a waveguide medium.
Journal ArticleDOI

C. Y. Wang,Lyuba Kuznetsova,Vasileios-Marios Gkortsas,Laurent Diehl,F. X. Kaertner,Mikhail A. Belkin,A. A. Belyanin,Xiangping Li,Donhee Ham,Harald Schneider,P. D. Grant,C. Y. Song,S. Haffouz,Z. R. Wasilewski,H. C. Liu,Federico Capasso +15 more
TL;DR: In this article, mode-locking dynamics in a small section of an edge-emitting quantum cascade laser (QCL) were modeled and simulated based on the Maxwell-Bloch equations in an open two-level system.

Generation of 36-femtosecond pulses from a ytterbium fiber laser
TL;DR: By optimizing the cavity dispersion map, 1.5-nJ, 36-fs pulses are obtained from a Yb-doped fiber laser with higher-order dispersion, which limits the pulse duration.
Journal ArticleDOI
Generation of 36-femtosecond pulses from a ytterbium fiber laser
TL;DR: By optimizing the cavity dispersion map, 1.5-nJ pulses as short as 36 fs were obtained from a Yb-doped fiber laser as mentioned in this paper, where residual higher-order dispersion currently limits the pulse duration.
