OPTICAL AMPLIFIER ARRANGEMENT COMPRISING A MULTIPASS CELL

WIPO Patent Application WO/2022/078620

A3

The invention relates to an amplifier arrangement for increasing power and energy, comprising a multipass cell and at least one amplifying medium, the multipass cell having concavely curved mirrors, and the amplifying medium being arranged inside the multipass cell such that the pump radiation passes through the amplifying medium multiple times and is absorbed by the amplifying medium, and a laser beam to be amplified passing through the amplifying medium. The mirrors are designed and arranged such that a White multipass cell is formed and the pump radiation and the laser beam to be amplified have large cross-sections at the positions at which mirrors and amplifying media are arranged. An arrangement is also provided in which a highly reflective mirror and a partially transmissive mirror are provided, which form a laser resonator in the form of a laser oscillator in interaction with the multipass cell.
