This high-dispersion chirped mirror provides GDD compensation across the 710–980 nm spectral range with \u0026gt;99.8% reflectance, making it an essential component for pre-chirping and dispersion management in Ti:Sapphire-based ultrafast laser systems.\u003c\/p\u003e\n  \u003cp\u003eWith moderate positive GDD of 100 fs² per bounce, this mirror enables practical dispersion compensation in compact geometries—approximately 60 bounces compensate 6000 fs² of accumulated GVD. The positive dispersion characteristic makes it ideal for pre-compensation before compressor stages in chirped pulse amplification (CPA) systems and for fine-tuning pulse duration in oscillator cavities operating around 800 nm.\u003c\/p\u003e\n  \n  \u003ch3\u003eApplications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTi:Sapphire CPA Pre-Chirping:\u003c\/strong\u003e Positive GDD compensation before stretcher-amplifier chains to optimize recompression and minimize higher-order dispersion\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOPCPA Pump Line Dispersion Management:\u003c\/strong\u003e Fine-tuning temporal overlap between pump and signal pulses in optical parametric chirped pulse amplification systems\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTi:Sapphire Oscillator Cavity Tuning:\u003c\/strong\u003e Intracavity dispersion control for sub-100 fs pulse generation at 800 nm wavelengths\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOPA Pumping Systems:\u003c\/strong\u003e Pulse conditioning in regenerative amplifiers driving optical parametric amplifiers in the near-IR\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n  \u003cp\u003eManufactured on 100 mm diameter, 25 mm thick UVFS substrate with ion beam sputtered (IBS) multilayer dielectric coating. Specified for P-polarization at 5° angle of incidence (AOI) with R\u0026gt;99.8% across the full 710–980 nm bandwidth. The HD1561 design features ultralow loss and tight GDD tolerance, ensuring predictable dispersion behavior in multi-bounce configurations.
