Mode Locked Fiber Ring Laser Based High Power Oscillator System
Realizing a practical mode lock fiber oscillator with both high repetition rate and high pulse energy has been a very challenge work of the ultrafast fiber laser for more than twenty years. Although many mode lock fiber laser structures have been attempted since the 1990 & apos;s, none has fully met commercial requirements for ultra-short high power fiber laser. In this SBIR program, Agiltron will produce a mode lock fiber laser with pulse energy of 100 J and repetition rate of 100 MHz on recently developed understanding of single wall carbon nano-tube absorber (SWCNT) and large mode area rod type photonic crystal fiber. Two key methods will allow us to achieve unprecedented performance; the high energy similariton pulses generating in short ring laser cavity, and the hybrid chirp pulse amplifier with nonlinear spatial phase modulator. In Phase I, Agiltron will design, fabricate and demonstrate the mode lock ring fiber oscillator with pulse energy of J and high repetition rate of 100 MHz. In Phase II, a complete ultra fast fiber laser system will be demonstrated with high beam quality and high pulse energy of 100 J. Commercial Applications and Other Benefits: Ultrafast fiber lasers are well established in many areas of optical science and technology, and have turned into a profitable business for many companies in widely different application areas. The applications include modern ophthalmology, microscopy, micromachining, optical communications, fiber frequency comb, photo-injectors, free electron laser seeding, current-enhanced self amplified spontaneous emission (ESASE), laser-ion stripping of hydrogen beams, and laser wire beam profile measurements in proton particle accelerators.
