355 nm Ultraviolet Lasers

355 nm is the third harmonic (THG) of Nd:YAG and Nd:YVO₄ lasers, offering high UV absorption across polymers, ceramics, and semiconductors without the atmospheric absorption of deeper UV lines. It is the industrial standard for stereolithography (SLA resin curing), laser micro-machining, silicon wafer scribing, PCB via drilling, and UV flow cytometry (DAPI, Hoechst, Indo-1). Models include CW, high-repetition-rate Q-switched, and picosecond formats.
