High Average Power Ultrafast Thin-Disk AmplifiersThin-disk regenerative amplifiers are routinely used for generating multi-millijoule pulses withdurations of < 2 ps at kilohertz repetition rates [1-3] and demonstrated recently record values of220 mJ at 1 kHz [4]. Derived from industrial micro machining lasers [5] and high power cw lasers
for laser cutting and laser welding [6], this technology was initially developed for pumping opticalparametric chirped pulse amplifiers (OPCPA) [7,8] revolutionizing attosecond technology [9]. Latest
results demonstrate that kilohertz thin-disk regenerative amplifiers are scalable beyond the kilowatt
average power level uncovering new perspectives of applications. Laser based lightning rod[10,11], X-ray lasers [12] and inverse Compton scattering [13] are among them. The principle ofthese thin-disk amplifiers operated at ambient temperature is based on chirped pulse amplification.
This lecture gives an introduction into ultrafast high power thin-disk laser technology and thecurrent development at TRUMPF Scientific Lasers.
