Description

The OPTOMAN PP-UVFS-25.4-6.35-UBBHR18-NO-SSC is a premium IBS-coated broadband ultrafast laser mirror engineered for Ti:Sapphire laser systems operating across the 700–900 nm spectral range. Manufactured on a precision UV fused silica substrate, it delivers exceptionally high reflectivity, low group delay dispersion, and excellent resistance to high-power femtosecond laser pulses.

The mirror is optimized for a 45° angle of incidence, making it an ideal choice for ultrafast beam steering and laser cavity applications where pulse quality and long-term stability are critical. Its ion beam sputtered dielectric coating provides outstanding environmental durability and consistent optical performance for demanding scientific and industrial laser systems.

Frequently Asked Questions

What wavelength range is this mirror designed for?
The mirror is optimized for broadband operation from 700 nm to 900 nm, making it well suited for Ti:Sapphire ultrafast laser systems.
What is the advantage of IBS coating?
Ion Beam Sputtering produces dense, low-loss dielectric coatings with exceptional environmental stability, high reflectivity, excellent coating uniformity, and long service life under demanding laser conditions.
What does the NO-SSC version mean?
The NO-SSC configuration features an uncoated rear surface instead of a stress-compensating coating, making it suitable for applications where a standard uncoated backside is preferred.
Is this mirror suitable for femtosecond lasers?
Yes. The mirror is specifically designed for ultrafast laser applications with low group delay dispersion and a high laser-induced damage threshold to preserve pulse quality.
Which applications benefit most from this mirror?
This mirror is commonly used in Ti:Sapphire laser cavities, ultrafast spectroscopy, nonlinear optics, multipass cells, chirped pulse amplification systems, and other precision photonics setups requiring broadband, low-dispersion reflection.
