Flexible and Programmable Pulse Shaping MOPA Fiber Laser Platform, Performances and Applications

抄録

Optical fiber amplifiers used in a MOPA architecture open up a lot of possibilities for developing flexible laser sources, thanks to their efficiency, their high single-pass gain, broad spectral gain bandwidth and intrinsic high beam quality and stability. Combining fiber amplifiers with advanced digital electronics, used for synchronizing and modulating high-speed signals for the generation of programmable nanosecond pulse shapes and bursts of picosecond pulses, can make remarkable laser sources offering unprecedented opportunities for the exploration of laser-matter interactions on a wide and fine scale. Those monolithic laser sources show great potential as development tools for speeding up the optimization of laser materials processing as well as sufficient maturity and robustness to be used as single, multi-role laser sources, working in industrial environment and performing multiple tasks requiring wildly varying laser parameters.
