SP-B-355-E
The SP-B-355-E 355 nm AOM Q-switched UV laser is a high-performance solid-state laser source engineered for applications requiring high photon energy, precise pulse control, and excellent beam quality. Operating at 355 ±1 nm, the laser uses acousto-optic Q-switching to generate stable nanosecond pulses at repetition rates up to 100 kHz.
With an average output power of up to 5 W and single pulse energies reaching 250 µJ, the SP-B-355-E delivers peak powers of up to 10 kW, making it highly suitable for 3D laser marking, sub-surface engraving, micro-machining, and advanced scientific instrumentation. The laser provides excellent beam parameters, high polarization purity (>100:1), and long-term operational stability.
