Document Type and Number:
WIPO Patent Application WO/2019/113816
Kind Code:
A1
Abstract:
A double pulse ring laser amplifier for annularly amplifying two laser pulses, comprising a first optical path and a second optical path that form the annular optical path structure; the first optical path including a first polarizer (1), a second polarizer (8), a first internal optical path assembly disposed between the first polarizer (1) and the second polarizer (8), a first deformable mirror (10) and a first polarization rotating device (9) disposed between the second polarizer (8) and the first deformable mirror (10), wherein the first internal optical path assembly includes a first laser amplifier (2), a first spatial filter (21), a first photoelectric switch (6) and a second laser amplifier (7); the second optical path including a third polarizer (13), a fourth polarizer (20), a second internal optical path assembly disposed between the third polarizer (13) and the fourth polarizer (20), a second deformable mirror (11) and a second polarization rotating device (12) disposed between the third polarizer (13) and the second deformable mirror (11), wherein the second internal optical path assembly includes a third laser amplifier (14), a second photoelectric switch (15), a second spatial filter (22) and a fourth laser amplifier (19).
