Negative GDD for Dispersion Compensation Application Setup
The Negative GDD for Dispersion Compensation setup is a compact, high-efficiency optical system designed to reverse pulse broadening in ultrafast laser systems. Utilizing a matched pair of chirped mirrors, this configuration enables precise control of group delay dispersion (GDD) through multi-bounce reflection. Each bounce off the mirror surface introduces –45 fs² of GDD at 800 nm, allowing users to fine-tune dispersion compensation for sub-10 fs pulses. The system is optimized for minimal footprint using Newport’s patented clear quadrant mounts.
Features
- Chirped mirrors provide –45 fs² GDD per bounce at 800 nm
- Enables multi-bounce setups for precise dispersion control
- Compact configuration using clear quadrant mirror mounts
- Proprietary coating design for higher-order dispersion management
- All components tested and certified for ultrafast laser compatibility
FemtoOptics™ Chirped Mirrors Matched Pair
This matched pair of ultrafast chirped mirrors offers high reflectivity and precision dispersion control for sub-10 fs pulses. The proprietary coating design ensures accurate management of higher-order dispersion while maintaining throughput and compact form factor.
The coating design of dispersion compensation mirrors naturally introduces oscillatory fluctuations across the active wavelength band. These oscillations are effectively cancelled when using a matched pair with phase-shifted designs, ensuring smoother dispersion performance.
Constructed from high-purity synthetic fused silica, these mirrors offer low thermal expansion, high refractive index homogeneity, and excellent transmittance from UV to NIR. Their high energy damage threshold makes them ideal for demanding ultrafast applications.
Applications
- Sub-10 fs pulse compression
- Ultrafast spectroscopy
- Nonlinear optics experiments
- Chirped pulse amplification (CPA) systems
- High-energy femtosecond laser systems
