Introduction

High-energy picosecond lasers are widely used in industrial, medical, and scientific research fields, such as laser marking, laser cleaning, laser beauty, laser ultrasound, etc. In solid-state lasers, it is difficult to directly obtain high-energy picosecond laser output through an oscillator. At present, the most effective method to obtain high-energy picosecond laser is the main oscillator stage-energy amplifier technology. Microchip picosecond laser (seed light) combined with lamp-pumped single-pass or multi-pass amplifier is a common solution, which has the advantages of compact structure and high cost performance.
