We present a diode-pumped Yb:YAG MOPA-System for the unprecedented generation of variable pulse duration transform limited pulses in the range between 10ps and 100ps. First applications relying on unique pulse parameters as modulation free spectrum, tunability and coherence length, namely the direct laser interference patterning (DLIP) and laser cooling of stored relativistic ion beams are highlighted. Pulses are generated by a mode-locked fs-oscillator while the spectral bandwidth is narrowed in the subsequent regenerative amplifier by an intra-cavity grating monochromator. Two alternative booster amplifiers were added to increase the pulse energy to 100µJ and 10mJ, respectively.
