Sub-2-Cycle Carrier-Envelope-Phase–Stabilized 110W, 1.1mJ Laser (AM2A.2)
Presenter: Tino Eidam, Activer Fiber Systems GmbH

We present a sub-2 cycle laser system combining 110W average power, 1.1mJ pulse energy at 100kHz repetition rate with CEP-stable operation making this system an ideal driver for next-generation attosecond sources.

High Energy Pulsed Operation of a Tapered Rod-Type Multicore Fiber Amplifier (AM2A.3)
Presenter: Christopher Aleshire, Friedrich-Schiller University Jena

Nanosecond-class pulse energies up to 32 mJ are obtained from a tapered rod-type multicore fiber. The tapered fiber improves output beam quality in large multimode cores, with targeted application in ultrafast coherently combined systems.

Thin-Disk Based Regenerative Chirped Pulse Amplifier With 550 mJ Pulse Energy at 1 kHz Repetition Rate (AM2A.5)
Presenter: Yanik Pfaff, TRUMPF Scientific Lasers GmbH + Co. KG

We demonstrate a thin-disk based regenerative amplifier system with a maximum pulse energy before compression of 550 mJ at a repetition rate of 1 kHz. A fraction of the output was recompressed to 602 fs.

Multi-Kilowatt Ultrafast Laser With Thin-Disk Technology (AM2A.6)
Presenter: Johanna Dominik, TRUMPF Laser GmbH

We present a thin-disk multipass amplifier as a power scaling architecture for ultrafast lasers. 1950 W output power at a repetition rate of 800 kHz were achieved with pulses pre-compressed to 10 ps.
