Description

The OPTOMAN PP-UVFS-25.4-6.35-AR548-AR548 is a premium optical window engineered for ultrafast laser systems operating at 1030 nm. Manufactured from high-purity UV fused silica (Corning 7980 0F), this precision optical window combines exceptional transmission, excellent wavefront quality, and a high laser-induced damage threshold (LIDT), making it ideal for demanding femtosecond and picosecond laser applications.

Both optical surfaces feature advanced Ion Beam Sputtered (IBS) anti-reflective coatings with reflectance below 0.1% at 1030 nm, minimizing Fresnel losses and unwanted back reflections while maximizing optical throughput. The IBS coating technology also provides excellent environmental stability, long-term durability, and superior coating uniformity compared to conventional deposition methods.

With a 25.4 mm diameter, 6.35 mm thickness, λ/10 surface flatness, and 10-5 scratch-dig surface quality, this laser window preserves beam quality while protecting sensitive optical systems from dust, airflow, and environmental contamination. Its estimated LIDT exceeding 0.5 J/cm² (1030 nm, 500 fs, 10 kHz) makes it well suited for high-peak-power Yb:YAG ultrafast laser platforms used in precision manufacturing, scientific research, and advanced photonics.

Frequently Asked Questions

What is the primary purpose of this optical window?
The PP-UVFS-25.4-6.35-AR548-AR548 serves as a protective optical interface that seals laser systems from dust, airflow, and environmental contaminants while allowing maximum transmission at 1030 nm with minimal reflection and wavefront distortion.
Why are IBS anti-reflective coatings beneficial?
Ion Beam Sputtering produces dense, durable optical coatings with extremely low absorption, excellent environmental stability, and high transmission. The coatings also reduce back reflections that can negatively affect high-coherence ultrafast laser systems.
Is this window suitable for femtosecond lasers?
Yes. It is specifically designed for femtosecond and picosecond laser applications around 1030 nm and offers a high estimated laser-induced damage threshold together with excellent transmitted wavefront quality.
Which laser systems can use this optical window?
The window is optimized for Yb:YAG-based ultrafast lasers operating at 1030 nm, making it suitable for numerous commercial laser platforms used in industrial processing, scientific research, and precision manufacturing.
Why is surface flatness important for laser windows?
High surface flatness minimizes transmitted wavefront distortion, helping preserve beam quality, focusability, and pointing stability. This is especially important in precision laser applications where optical aberrations can reduce processing accuracy or experimental repeatability.
