Multilayer coating optimized to maximize negative GDD per reflection while preserving high reflectance — the standard approach for fs-laser CPA compressor design.\u003c\/p\u003e\n\n  \u003ch3\u003eApplications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eultrafast micromachining beam delivery\u003c\/li\u003e\n    \u003cli\u003eOPA\/OPCPA pumping at 1030 nm\u003c\/li\u003e\n    \u003cli\u003eYb:YAG regenerative amplifier post-compression\u003c\/li\u003e\n    \u003cli\u003eindustrial fs-laser dispersion management for materials processing\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n  \u003cp\u003eManufactured on a 25.4 mm diameter × 6.35 mm thick UV fused silica (UVFS) substrate with ion beam sputtered (IBS) dielectric multilayer coating, \u0026gt;99% reflectance specified as \u003cem\u003eR\u0026gt;99%@1000-1060nm\u003c\/em\u003e. The mirror operates at 5° angle of incidence with p-polarized light. The IBS coating provides exceptional layer density, sub-ppm absorption losses, and long-term spectral stability — characteristics required for dependable performance in high-average-power amplifier chains.\u003c\/p\u003e\n  \u003cp\u003e1030 nm Yb-band IBS dielectric coating with optimized GDD flatness ensures consistent dispersion control under typical fs-laser operating conditions.
