Abstract :
We report on a high energy CPA system based on amplification in low-nonlinearity photonic crystal fibers. The resulting output of pulse energies of 100 muJ in ultrashort pulses with high repetition rates are applied to high speed micromachining. e.g. the drilling of holes in 1 mm thick steel
