Overview
The 800nm Chirped Mirror -80fs² (Ultrafast Innovations CM347, 12.7mm diameter) delivers precise negative GDD of -80 fs² per bounce for dispersion compensation in Ti:Sapphire laser systems operating across 750–850 nm. This standard-regime chirped mirror provides the optimal GDD magnitude for compact oscillator cavity designs and multi-pass amplifier dispersion management without requiring excessive bounce counts.
At -80 fs² per reflection, this mirror enables practical dispersion compensation architectures: compensating typical cavity round-trip GDD of ~800 fs² requires only 10 bounces, while managing accumulated material dispersion of 6000 fs² in CPA systems needs approximately 75 reflections. This GDD value strikes the ideal balance between compensation efficiency and mechanical compactness, making it the workhorse solution for sub-100 fs pulse duration systems where ultra-high bounce counts are impractical.
Applications
- Ti:Sapphire oscillator intracavity dispersion compensation – maintaining sub-30 fs pulse durations in Kerr-lens mode-locked resonators
- CPA stretcher/compressor GDD fine-tuning – balancing residual higher-order dispersion in chirped pulse amplification systems
- OPA and OPCPA pump beam conditioning – pre-compensating dispersion in 800nm pump lines for optimal parametric conversion efficiency
- Multi-pass amplifier dispersion control – compensating accumulated GVD through gain crystals and transmissive optics in regenerative and multi-pass Ti:Sapphire amplifiers
Construction & Performance
Manufactured on 12.7 × 6.35 mm UVFS substrate with ion beam sputtering (IBS) deposited multilayer coating, this P-polarized chirped mirror achieves R > 99.98% reflectance across the full 750–850 nm bandwidth at 3° angle of incidence. The ultralow loss design minimizes thermal loading in high-repetition-rate oscillators. LIDT specification of 0.2 J/cm² supports femtosecond pulse handling in both oscillator and amplifier environments. The compact form factor enables dense packing in folded beam geometries and mirror pair configurations.
Storage & Handling
Operate at 25 °C, 40–60% RH. Clean only with >99% optical-grade ethanol and lint-free lens tissue using single-pass drag method. Avoid abrasive cloths and water.
