Optical arrangement

Abstract

An optical arrangement includes a laser-active solid body configured to amplify and/or generate a laser beam. The laser-active solid body is in a form of a slab. The optical arrangement further includes a pump radiation source configured to generate a pump beam that propagates in a propagation direction and passes through the laser-active solid body for optical pumping the laser-active solid body, and a reflector arranged downstream of the laser-active solid body in the propagation direction of the pump beam. The reflector is configured to reflect the pump beam transmitted through the laser-active solid body back onto the laser-active solid body. The pump beam reflected by the reflector passes through the laser-active solid body for optical pumping the laser-active solid body.
