Advances in All-Solid-State Passively Q-Switched Lasers Based on Cr4+:YAG Saturable Absorber
All-solid-state passively Q-switched lasers have advantages that include simple structure, high peak power, and short sub-nanosecond pulse here width.Potentially, these lasers can be applied in multiple settings, such as in miniature light sources, laser medical treatment, remote sensing, and precision processing.Cr4+:YAG crystal is an ideal Q-swit
