Abstract: The invention relates to a multi-pass laser system (1) with a beam coupling optical unit (2) and a beam uncoupling optical unit (3) for guiding an incident (4) and an emergent (5) radiation field and with a multi-pass cell (6), which multi-pass laser system comprises at least one or two focusing optical units (7) and two feedback optical units (8, 9) for guiding a multi-pass radiation field (11) consisting of a plurality of radiation branches (12) that extend in parallel in an intermediate zone (13) delimited by the focusing optical unit (7) and that are guided, via the focusing optical unit (7), onto one of the feedback optical units (8, 9) where they superimpose and penetrate a solid-state disk (14) arranged in front of one of the feedback optical units (8, 9) while superimposing one another in an active zone, said branches being coupled such that, proceeding from the incident (4) to the emergent (5) radiation field, all radiation branches (12) are passed through one by one. The multi-pass laser system is characterized for example in that the multi-pass laser system (1) comprises at least two multi-pass cells (6) and in that one of the feedback optical units (8, 9) is designed as a "common coupling optical unit" (10) to couple the two multi-pass radiation fields (11) of the two multi-pass cells (6) to one another.

Abstract: The invention relates to a laser amplifier system (1) with a solid state disk (2) comprising a laser medium and having two flat faces (3, 4), functional layers (5) comprising a reflector for a pump radiation field (6) and a reflector for a laser radiation field (7) being arranged on the first flat face (3), and the functional layers (5) being thermally and mechanically coupled to a cooling surface (8) of a cooling body (9) to dissipate heat, the coupling being brought about at least to some extent by an adhesive layer (10) that is arranged between the cooling body (9) and the functional layer (5). The laser amplifier system is characterized in that the adhesive layer (10) is formed by an adhesive that substantially changes its volume during transition from the liquid to the solid state. The invention further relates to a method for producing the laser amplifier system (1) according to the invention.
