Title: Modular, high energy, widely-tunable and ultrafast fiber source
Inventor: FERMANN MARTIN E
IPC: H01S3/16
Filed: 2001-05-23
Abstract: PROBLEM TO BE SOLVED: To provide a modular, compact and widely-tunable laser system for efficiently generating a high peak ultrashort pulses. SOLUTION: System compactness is ensured by employing efficient fiber amplifiers, directly or indirectly pumped by diode lasers. Peak power handling capability of the fiber amplifiers is expanded by using optimizing pulse shapes as well as dispersively broadened pulses. Dispersive broadening is introduced by dispersive pulse stretching in the presence of self-phase modulation and gain, resulting in the formation of high-power parabolic pulses. After amplification, the dispersively stretched pulses can be recompressed to nearly band width limit by the implementation of another set of dispersive delay lines. To ensure a wide tunability of the whole system, Raman-shifting of the compact sources of ultrashort pulses in conjunction with frequency-conversion in nonlinear optical crystals can be implemented.  Further, a positively dispersing optical amplifier and a Raman amplifier fiber are utilized.
