Description

The OPTOMAN PP-UVFS-50.8-9.52-LLM267EL is a premium non-degrading ultrafast laser mirror engineered for demanding 343 nm laser applications. Manufactured on a high-quality UV fused silica (JGS1) substrate and coated using advanced Ion Beam Sputtering (IBS) technology, this mirror delivers exceptional reflectivity, high laser-induced damage threshold (LIDT), and outstanding long-term stability under continuous UV exposure.

Designed specifically for 45° angle of incidence with s-polarized light, the mirror provides greater than 99.6% reflectivity across the 337–349 nm wavelength range while maintaining excellent wavefront quality with λ/10 surface flatness. Unlike conventional UV dielectric mirrors that gradually degrade under prolonged high-power irradiation, the Enhanced Lifetime (EL) coating technology is designed to resist UV-induced coating degradation, extending operational lifetime beyond 10,000 hours and reducing maintenance requirements.

With its high optical performance and durability, the PP-UVFS-50.8-9.52-LLM267EL is an excellent choice for industrial femtosecond and picosecond laser systems used in precision manufacturing, microelectronics, scientific research, and advanced photonics applications.

Frequently Asked Questions

What laser wavelength is this mirror optimized for?

The PP-UVFS-50.8-9.52-LLM267EL is optimized for 343 nm laser systems and provides greater than 99.6% reflectivity across the 337–349 nm wavelength range when used with s-polarized light at a 45° angle of incidence.

What makes the Enhanced Lifetime coating different from conventional UV mirrors?

The Enhanced Lifetime (EL) coating is designed to resist UV-induced coating degradation that commonly affects standard dielectric mirrors. This significantly extends operational life, minimizes performance drift, and reduces maintenance and replacement costs in high-duty-cycle laser systems.

Can this mirror be used with ultrafast femtosecond lasers?

Yes. The mirror is specifically designed for ultrafast femtosecond and picosecond laser applications and features a high laser-induced damage threshold suitable for demanding high-peak-power laser systems.

Which applications benefit most from this mirror?

This mirror is particularly well suited for UV laser micromachining, through-glass via (TGV) production, precision glass drilling, semiconductor manufacturing, polymer processing, and scientific laser research requiring stable long-term UV performance.

Why is UV fused silica used as the substrate?

UV fused silica offers excellent transmission in the ultraviolet spectrum, low thermal expansion, high optical homogeneity, and exceptional resistance to laser-induced damage, making it an ideal substrate for high-performance UV laser optics.
