CNI’s self-developed and manufactured 349 nm continuous-wave
(CW) and actively Q-switched pulsed UV laser series covers both continuous
output and actively Q-switched pulsed models, with core advantages including
low noise, high stability, narrow spectral linewidth and excellent beam
quality.
Supporting air or water cooling, they enable stable 24/7
operation with internal and external modulation control, and are fully
compatible with OEM integration. These lasers are widely used in spectral
analysis, semiconductor inspection, biomedicine, advanced scientific
research and precision machining.
