Operating across the 755–805 nm spectral range with 99.94% reflectance, this \u003cstrong\u003e780nm chirped mirror\u003c\/strong\u003e enables efficient \u003cstrong\u003eGDD compensation\u003c\/strong\u003e in oscillators and CPA systems where intracavity space is constrained.\u003c\/p\u003e\n  \u003cp\u003eWith |GDD| = 1000 fs²\/bounce, this high-dispersion mirror allows 6-bounce compensation of typical 6000 fs² dispersion accumulated through gain media and optics, significantly reducing compressor footprint compared to conventional -500 fs² mirrors. The large negative GDD per reflection makes it ideal for systems requiring substantial group velocity dispersion (GVD) correction in minimal space, particularly in enclosed oscillator cavities and pre-compression stages of chirped pulse amplification (CPA) chains.\u003c\/p\u003e\n  \n  \u003ch3\u003eApplications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTi:Sapphire oscillator intracavity dispersion compensation\u003c\/strong\u003e – sub-10 fs pulse generation with compact mirror pair configuration\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCPA and OPCPA pre-compression\u003c\/strong\u003e – GDD management before regenerative or multipass amplifiers at 800 nm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOPA pump line dispersion control\u003c\/strong\u003e – temporal pulse shaping for optimized parametric conversion efficiency\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFemtosecond Ti:Sapphire amplifier systems\u003c\/strong\u003e – post-amplification pulse compression with reduced bounce count\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n  \u003cp\u003eManufactured on 38.1 mm diameter, 12.7 mm thick UVFS substrate with ion beam sputtering (IBS) deposited multilayer coating optimized for P-polarization at 5° angle of incidence (AOI). The chirped dielectric stack achieves R \u0026gt; 99.94% across the full 755–805 nm bandwidth while maintaining -1000 ±50 fs² GDD specification. LIDT rating of 0.2 J\/cm² supports femtosecond pulse energies typical in Ti:Sapphire oscillators and amplifier beam paths. Precision substrate flatness and IBS coating uniformity ensure wavefront preservation across multiple bounces in folded compressor geometries.\u003c\/p\u003e\n  \n  \u003ch3\u003eStorage \u0026amp; Handling\u003c\/h3\u003e\n  \u003cp\u003eOperate at 25 °C, 40–60% RH.
