Overview
The 2000-5000nm Chirped Mirror -250fs² is a dielectric chirped mirror engineered for dispersion management in mid-infrared (MWIR) ultrafast laser systems. Reflectance band 1700–2700 nm centered near 2200 nm. Group delay dispersion of -250 fs² per bounce serves as a compressor for Cr:ZnSe / Cr:ZnS, OPO / OPA, Tm:fiber / Ho:fiber, and Ho:YAG / Er:YAG architectures that demand sub-100 fs control at telecom-extended and mid-IR wavelengths.
Applications
- Tm:fiber / Ho:fiber CPA stretcher-compressor matching
- 2.2 µm OPCPA dispersion engineering (-250 fs²/bounce)
- Mid-IR ultrafast amplifier dispersion management
- Sub-100 fs 2 µm pulse compression
Construction & Performance
- Substrate: UVFS, 25.4 mm × 6.35 mm
- Coating: Dielectric Coating, R>99.2%@1700-2700nm
- Angle of incidence: 0°
- Polarization: P
- Damage threshold: 0.2 J/cm² @ 800 nm reference (fs pulses)
Storage & Handling
Store in low-humidity dry cabinet with optical-grade lens tissue protection. Handle by the edges only — coating surface contact will degrade reflectance and damage threshold. Clean with high-purity acetone or methanol using the drop-and-drag technique; never wipe across the coated face. Avoid extreme temperature gradients that can cause stress birefringence in the substrate.
