This requirement is for a high energy green laser to be used to pump an existing Ti:Sapphire regenerative amplifier (Legend, Coherent) and facilitate future Ti:Sapphire laser amplifier upgrades at UKRI (UK Research and Innovation) STFC (Science and Technology Facilities Council), Daresbury Laboratory.

The Legend amplifier consists of a (first-stage) regenerative amplifier (2.8 mJ, 1 kHz target nominal performance) and (second-stage) multi-pass amplifier (800 mJ, 10 Hz, following compression). The pump laser as specified herein is for the regenerative amplifier stage. The age of the Legend system, including the existing pump laser, is now approaching 12 years old and a new pump laser is required due to performance degradation over this period.

Detailed High Energy Green Pump Laser requirements are defined in the attached document,UK SBS PR19082 Specification.
