AMPLIFIER DEVICE AND METHOD FOR AMPLIFYING LASER PULSES

摘要

A laser pulse amplifier device (100) includes an amplifying cavity (10) comprising an amplifying laser gain medium (11) and multiple cavity mirrors (12.1 to 12.7) spanning a cavity light path (13), wherein the amplifying cavity (10) is configured for an amplification of laser pulses (1) circulating along the cavity light path, and a multi-pass amplifier (20) being optically coupled with the amplifying cavity (10) and comprising multiple deflection mirrors (22) spanning a multipass light path (23), wherein the multi-pass amplifier (20) is configured for a post-amplification of laser pulses (2) coupled out of the amplifying cavity (10), wherein the amplifying cavity (10) and the multi-pass amplifier (20) are arranged such that the laser gain medium (11) of the amplifying cavity (10) is included as an active medium in the multi-pass light path (23) of the multi-pass amplifier (20). Furthermore, a method of amplifying laser pulses is described.
