This course provides an overview of the design, performance characteristics, the current state of the art, and the applications of industrial ultrafast lasers used in micro-processing. The course reviews the properties of Yb-doped and Nd-doped gain materials used to generate pulse durations in the range of 300 fs to 15 ps, and discusses the design principles for modelocked solid state and fiber MOPA architectures to realize average output powers of up to hundreds of Watts with pulse energies in the range of 1 µJ to several mJ. The course will cover the design of SESAM modelocked oscillators, the fundamentals of Chirped Pulse Amplification (CPA), including design rules for pulse stretching and compression devices, as well as frequency conversion to the green and ultraviolet spectral range. Topics will also include the interaction of fs/ps pulses with materials during laser processing and a review of the optimum fluences and maximum ablation rates in the IR, Green and UV for more than 25 materials used in industrial manufacturing. The course concludes with an overview of currently available laser products and their industrial applications and a summary of recent R&D results.
