Femtosecond lasers are inevitable for selective ablation or micro-machining of multi-component materials. The precise amount of energy addressed on the sample, in space and time, is a key point for the precise control of the process. In many cases, additional features are required for process enabling or optimization that do not automatically come with state-of-the-art high power femtosecond lasers: high power frequency conversion to the green or UV spectral region, free triggering with low jitter and high precision, bursts of pulses with user defined shapes, GHz pulse periods. In this contribution, we report on a versatile industrial high power femtosecond laser platform capable of delivering such features and thus responding to the most demanding application requirements. The platform generates femtosecond pulses at more than 100 W average power at a wavelength of 343 nm, free triggering of the laser output pulses, and burst generation and shaping over a wide range of parameters including GHz bursts.Moreover, the laser platform can operate in a temporal superposition mode emitting simultaneously or alternatively femtosecond pulses as well as picosecond or nanosecond pulses. All described laser features are motivated and illustrated by relevant laser application examples.
