Abstract
An amplifier arrangement for increasing power and energy includes a multipass cell and at least one gain medium, wherein the multipass cell has concavely curved mirrors and the gain medium is arranged within the multipass cell in such a way that the pump radiation passes through the gain medium multiple times and is absorbed by the gain medium and wherein a laser beam to be amplified passes through the gain medium, characterized in that 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, gain media and other optical components are arranged.

An amplifier arrangement for increasing power and energy, comprising a multipass cell and at least one gain medium, wherein the multipass cell has concavely curved mirrors and the gain medium is arranged within the multipass cell in such a way that a pump radiation passes through the gain medium multiple times and is absorbed by the gain medium and wherein a laser beam to be amplified passes through the gain medium, characterized in that 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 has cross-sections at the positions at which mirrors, gain media and other optical components are arranged which is larger than where the mirrors, gain media and other optical components are not arranged, characterized in that the laser beam to be amplified is coupled into the multipass pump arrangement for amplification, and characterized in that a shaping optical unit is arranged upstream of the input coupling of the laser beam to be amplified into the multipass pump arrangement which transforms the laser beam to be amplified to an astigmatic beam.
