چکیده
A stretched-pulse fiber laser with a nonlinear optical loop mirror (NOLM) that produces 100-fs pulses with 1-nJ energy is demonstrated. These results constitute a 30-fold increase in pulse energy over previously reported femtosecond fiber lasers with a NOLM. Compared with previous stretched-pulse lasers, this laser offers a cleaner spectrum and improved stability, with comparable pulse duration and energy. Implications for the construction of truly environmentally stable lasers are discussed.

Yb-Doped Single-Mode Fiber CPA Laser System
High peak power laser systems of up to petawatt [1] are based on chirped pulse amplification (CPA) technique [2]. In the CPA laser system, ultrashort pulses from an oscillator are first stretched below the nonlinear pulse distortion threshold to reduce the peak power and the amplified pulses are recompressed at the output by a compressor. Stable ultrashort pulse oscillator is necessary for CPA ...

While ultrafast (picosecond and femtosecond) lasers are an essential subset of the lasers used today in industry and the medical arena (for example, machining glass for smartphone screens for the former, and laser eye surgery for the latter), it is the use of ultrafast lasers in research that allows such lasers to show their true colors, sometimes literally. Indeed, science is where it all bega...
