High-energy femtosecond 1086/543-nm fiber system for nano- and micromachining in transparent materials and on solid surfaces

摘要

The first experimental results on a fiber laser system that generates femtosecond pulses with an energy of 1 μJ at a wavelength of 1086 and an energy of 300 nJ at a wavelength of 543 nm are presented. The pulse parameters at a wavelength of 1086 nm are optimized with respect to the effective frequency doubling. The high-energy fiber system makes it possible to solve several problems in the femtosecond material processing.
