Abstract

A dual-output thin-disk picosecond laser operating at 100 W with 1 kHz repetition rate is reported in this Letter. By elec-tronically adjusting the amplitude of the optical seed pulses that are injected into the laser cavity, the energy extracted from the gain medium can be shared between two pulses.

Amplified double pulses are subsequently spatially sepa-rated into two independent beams by a fast Pockels cell, compressed in one common compressor, and frequency -doubled with similar to 70% efficiency. This approach significantly decreases strain on the optics, as well as nonlinear effects, and is advantageous for power scaling. (c) 2022 Optica Pub-lishing Group
