Description
The OPTOMAN PP-UVFS-25.4-6.35-LLM302 is a premium ion beam sputtered (IBS) chirped mirror engineered for precise dispersion management in ultrafast laser systems operating at the second harmonic of Yb:YAG lasers (515 nm). Designed to introduce -200 fs² Group Delay Dispersion (GDD) per reflection over the 505–525 nm wavelength range at a 45° angle of incidence, this mirror enables efficient pulse compression while maintaining exceptional reflectivity and low optical losses.
Manufactured on a high-quality UV fused silica (UVFS) substrate, the mirror combines outstanding optical performance with excellent environmental stability and a high laser-induced damage threshold. Unlike prism or grating compressors, this compact dispersive mirror simplifies optical layouts while providing stable, alignment-insensitive pulse compression for demanding femtosecond laser applications.
