This high-GDD chirped mirror enables efficient pulse compression with minimal bounces—compensating ~6000 fs² of positive chirp requires only 5 reflections, reducing cavity complexity and alignment sensitivity compared to conventional low-GDD mirror pairs.\u003c\/p\u003e\n  \u003cp\u003eEngineered for the 780–830 nm bandwidth with P-polarization at 5° angle of incidence (AOI), this \u003cstrong\u003e805nm chirped mirror\u003c\/strong\u003e provides \u0026gt;99% reflectance across the full spectral range, making it ideal for intracavity GDD compensation in ultrafast oscillators and external CPA compressor stages where space constraints demand high dispersion per bounce.\u003c\/p\u003e\n  \n  \u003ch3\u003eApplications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTi:Sapphire Oscillator GDD Compensation:\u003c\/strong\u003e Intracavity dispersion management for sub-10 fs pulse generation, compensating positive GVD from gain media and cavity optics\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCPA System Pulse Compressors:\u003c\/strong\u003e Compact post-amplification compression stages in chirped pulse amplification setups operating near 800 nm\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOPA and OPCPA Pump Line Management:\u003c\/strong\u003e Dispersion pre-compensation for 800 nm pump beams in optical parametric amplifier systems to optimize temporal overlap\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHigh-Repetition-Rate Femtosecond Systems:\u003c\/strong\u003e Space-efficient dispersion control in industrial and scientific ultrafast laser platforms where compact footprint is critical\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n  \u003cp\u003eManufactured on 25.4 mm diameter × 6.35 mm thick UV-fused silica (UVFS) substrate for excellent thermal stability and low absorption at 800 nm. The multilayer dielectric coating is deposited via ion beam sputtering (IBS) to achieve R\u0026gt;99% from 780–830 nm with precise GDD control of -1300 fs² ±5%. Specified for P-polarization at 5° AOI, this chirped mirror supports laser damage threshold of 0.2 J\/cm² for femtosecond pulses, suitable for high-peak-power ultrafast applications.\u003c\/p\u003e\n  \n  \u003ch3\u003eStorage \u0026amp; Handling\u003c\/h3\u003e\n  \u003cp\u003eOperate at 25 °C, 40–60% RH.
