Ultrafast laser sources with both high average power and high peak powers at a high repetition rate have many important applications in areas such as high-harmonic generation (HHG), micromachining, and high power optical parametric amplification. In recent years, with the development of high power fiber laser technology, the output of femtosecond fiber laser systems has reached average powers of thousands of watts and peak powers of several gigawatts. However, the pulse duration and pulse energy is limited by the accumulated nonlinear phase in the nonlinear propagation in the fiber, since it will distort the pulse shape and even break the femtosecond pulses. To enhance the performance of femtosecond fiber laser, the nonlinear phase accumulation and compensation is most important optimization factor. Pulse propagation dynamics control is the important method in femtosecond fiber system. This talk will demonstrate the few-cycle laser pulse generation in fiber system with nonlinear process manipulation.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
