Abstract
Disclosed are a thin-disk regenerative amplifier and an amplification method. The thin-disk regenerative amplifier includes an input and output light path and an amplification light path. A seed laser is input into the thin-disk regenerative amplifier through the input and output light path, and reflected and amplified by the amplification optical path to obtain an amplified laser. After reaching a predetermined threshold, the amplified laser is output through the input and output light path. The input and output optical path includes an optical isolator, a first polarization beam splitter, an optical rotator, a second polarization beam splitter, a first reflective mirror, and a second reflective mirror. The amplification light path includes an input mirror, a thin-disk crystal, a pumping device, a first concave reflective mirror, and a second concave reflective mirror.
