With -250 fs² per bounce, this mirror provides balanced dispersion control for ultrafast laser systems requiring moderate total GDD correction—approximately 24 bounces compensate 6000 fs² of accumulated positive dispersion from optical components and amplifier media.\u003c\/p\u003e\n  \u003cp\u003eThis GDD value positions the WQ-CM-800-250 as an ideal solution for compact compressor geometries where higher bounce counts (50+ reflections) are impractical, yet finer dispersion tuning than high-GDD mirrors (-500 to -1000 fs²\/bounce) is essential. The -250 fs² specification enables precise compression of femtosecond pulses while maintaining manageable cavity dimensions in both double-pass and multi-pass configurations.\u003c\/p\u003e\n  \n  \u003ch3\u003eApplications\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTi:Sapphire CPA Systems:\u003c\/strong\u003e External pulse compression for 800 nm regenerative and multipass amplifiers generating sub-100 fs pulses\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOPCPA Pre-compression:\u003c\/strong\u003e GVD compensation in optical parametric CPA pump chains and seed stretcher\/compressor assemblies\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHollow-Core Fiber Compression:\u003c\/strong\u003e Post-compression dispersion management for few-cycle pulse generation systems\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMultiphoton Microscopy:\u003c\/strong\u003e Pulse width optimization for two-photon imaging systems requiring precise delivery of 50–200 fs pulses to biological samples\u003c\/li\u003e\n  \u003c\/ul\u003e\n  \n  \u003ch3\u003eConstruction \u0026amp; Performance\u003c\/h3\u003e\n  \u003cp\u003eManufactured on UVFS substrates, the WQ-CM-800-250 features ion beam sputtered (IBS) dielectric multilayer coatings engineered for P-polarization at standard angles of incidence (0–10°). The coating architecture delivers high reflectance (\u0026gt;99.5%) across the 750–850 nm bandwidth while maintaining the specified -250 fs² GDD with tight tolerances (±15 fs²). Designed for femtosecond laser operation, the mirror withstands 0.2 J\/cm² laser-induced damage threshold (LIDT) for pulse durations below 100 fs, ensuring reliable performance in multi-mJ CPA systems.\u003c\/p\u003e\n  \n  \u003ch3\u003eStorage \u0026amp; Handling\u003c\/h3\u003e\n  \u003cp\u003eOperate at 25 °C, 40–60% RH.
