High Power Thin Disk Laser

Kurzfassung

In this talk, the latest results for thin disk lasers will be presented. Thin disk lasers can be operated in cw-mode as well as in pulsed mode with pulse durations from 100 fs to microseconds. Results from different institutes and companies will be shown demonstrating the power/energy scalability of the thin disk laser design with good beam quality and high efficiency, simultaneously. Several German companies are selling thin disk lasers with up to 16 kW output power (cw) and with up to 1 kW average power (pulsed) with high energy and high repetition rate. Based on the latest results and numerical models the design of a multi 10 kW to multi 100 kW thin disk laser has been developed. This master-oscillator power-amplifier (MOPA) system is now under construction. The principle design ideas of this system will be given.
