Abstract：Picosecond lasers are characterized by high pulse energy，high power density，and low thermal effects，demonstrating exceptional performance in micro-machining，precision cuting，and other applications. They are widely utilized in fields such as laser processing，aerospace，and biomedical engineering.Passive Q 1 switchingtechnology，which achieves pulsed laser outputbymodulating the Q -factor of the resonator，hasbecome 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 structures，semiconductor saturable absorber mirrrs（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 passive Q -switching technology within picosecond pulsed laser systems and provides insights into the future development and applications of passive Q -switched picosecond lasers.

Keywords：picosecond laser;passive Q -switching technology；microchip laser;semiconductor saturable absorber mirror（SESAM）；bonded crystals
