Title:
HIGH-BRIGHTNESS PICOSECOND LASER SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/174034
Kind Code:
A1
Abstract:
A high-brightness picosecond laser system, comprising a fully polarization-maintaining fiber picosecond seed laser (1), a fiber collimator (2), a space isolator (3), a polarization splitting prism (5), a first-stage solid traveling wave amplifier (6), a second-stage solid traveling wave amplifier (7), and a third-stage solid traveling wave amplifier (8) which are sequentially arranged in the laser transmission direction. The first-stage solid traveling wave amplifier (6) is located on the transmission light side of the polarization splitting prism (5), the second-stage solid traveling wave amplifier (7) is located on the reflected light side of the polarization splitting prism (5), and the fiber collimator (2) is connected to the fully polarization-maintaining fiber picosecond seed laser (1) by means of a tail fiber. The picosecond laser system is simple in structure, stable in performance and easy to maintain, can realize high-brightness 1064-nm laser output, and can realize green light output exceeding 50 W by arranging a frequency multiplication module (9) which is easy to integrate and disassemble.
