640-660nm laser

Fomoptic delivers integrated one‑stop optical solutions covering precision optical fabrication and custom vacuum coating services. Supported by complete processing production lines, comprehensive metrology equipment and experienced engineering team, we provide full‑chain customized components, ranging from blank shaping, ultra‑precision polishing to thin‑film coating, for laser systems, infrared imaging, industrial optics and scientific‑research projects.

Fiber lasers and fiber amplification systems require excitation sources with stable wavelength, narrow spectral linewidth and consistent output power.

For pulsed laser and full-spectrum optical testing, photodiodes and thermopiles have inherent drawbacks. Photodiodes show weak response in infrared band, while thermopiles feature slow response and cannot capture nanosecond narrow pulses.

As a professional ultraviolet‑laser solution provider, Precilasers has launched its 266 nm narrow‑linewidth industrial laser, delivering reliable single‑frequency output for high‑precision interference lithography, semiconductor inspection and precision metrology applications.
