Precilasers 266 nm Narrow‑Linewidth Laser for Semiconductor Micro‑Nano Fabrication

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.

Built upon single‑frequency seed laser, fiber amplification and high‑efficiency frequency conversion technologies, this laser reaches a maximum output power of 2 W. It features narrow linewidth, superior beam quality, outstanding frequency stability, mode‑hop‑free operation and long service lifetime.

During interference‑exposure processes, the laser emits uniform, stable coherent light. When coupled with high‑precision optical assemblies, it generates well‑defined interference fringes, enabling accurate pattern transfer onto photoresist layers for semiconductor micro‑nano‑structure manufacturing.

Beyond off‑the‑shelf laser sources, Precilasers offers comprehensive custom‑development services. Tailored wavelength and power configurations, as well as application‑oriented optical integration solutions, are available for laboratory research, prototype development and mass‑production workflows. These flexible options cover precision measurement and semiconductor inspection, empowering partners to accelerate technical innovation and improve manufacturing efficiency.
