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