Research Progress on 1 064nm Passively Q-switched Picosecond Lasers
摘要
Abstract
Picosecond lasers are characterized by high pulse energy,high power density,and low thermal ef-fects,demonstrating exceptional performance in micro-machining,precision cutting,and other applications.They are widely utilized in fields such as laser processing,aerospace,and biomedical engineering.Passive Q-switching technology,which achieves pulsed laser output by modulating the Q-factor of the resonator,has be-come a key method for generating picosecond lasers.This paper reviews the application of passive Q-switching technology in obtaining picosecond pulses,with a focus on three distinct technical approaches:microchip struc-tures,semiconductor saturable absorber mirrors(SESAMs)as saturable absorbers,and bonded crystals,all aimed at shortening the cavity length to achieve picosecond pulses while enhancing other performance aspects.It summarizes recent significant advancements in 1 064 nm passive Q-switching technology within picosecond pulsed laser systems and provides insights into the future development and applications of passive Q-switched pi-cosecond lasers.关键词
