High-Precision Fused Silica Super Stable Cavity-Circular Cavity Overview

Engineered for laboratories demanding extreme stability, the Fused Silica Super Stable Cavity-Circular Cavity redefines precision in frequency stabilization and quantum optics. Combining ultra-low expansion fused silica with a vibration-resistant circular design, this cavity maintains sub-atomic dimensional stability even under thermal shocks or mechanical stress. Whether you’re stabilizing optical clocks or enhancing gravitational wave detection systems, our cavity’s customizable geometries and proprietary coatings ensure unmatched performance.

Key Technical Specifications

Material: Corning 7980 ultra-low expansion fused silica offers exceptional dimensional stability, ideal for high-precision optics in gravitational wave detectors and semiconductor lithography. Its purity minimizes light scatter, ensuring uncompromised beam quality in laser systems and interferometers.
Thermal Stability: Coefficient of Thermal Expansion (CTE) < 5×10⁻⁹/K (0–50°C) prevents dimensional shifts in atomic clocks and quantum computing rigs, maintaining accuracy even with ambient temperature fluctuations that would disrupt sensitive measurements.
Mechanical Drift: Aging rate < 3×10⁻¹⁵/day ensures long-term precision in space-borne instruments and metrology systems, where gradual changes could invalidate data over extended missions or calibration cycles.
Dimensions: Standard Ø50–150mm (customizable up to Ø500mm) accommodates diverse setups, from compact lab lasers to large telescope mirrors, ensuring seamless integration without compromising structural integrity or performance.
Surface Quality: < 1Å roughness; optional HR/AR coatings minimize light loss and scatter, critical for high-power lasers and quantum communication links. Coatings enhance reflectivity/transmittance, optimizing efficiency in specialized optical systems.
Vacuum Compatibility: Operational at 10⁻⁸ Torr makes it suitable for space telescopes and vacuum chamber experiments, resisting outgassing that could contaminate sensitive components or distort optical paths in low-pressure environments.

Research Applications

Quantum optical clock stabilization: Leverages Corning 7980 fused silica’s ultra-low expansion and <5×10⁻⁹/K CTE to lock laser frequencies, ensuring <1e-18 fractional stability. This precision, paired with minimal mechanical drift, keeps atomic lattice systems synchronized for global time standards.
Low-noise laser frequency references: Benefits from <1Å surface roughness and HR coatings to reduce amplitude noise, critical for stabilizing lasers in quantum communication. The vacuum-compatible design (10⁻⁸ Torr) ensures consistent performance in lab-grade reference setups.
Cavity-enhanced spectroscopy: Uses customizable Ø50–500mm fused silica cavities with AR coatings to amplify weak absorption signals. Thermal stability <5×10⁻⁹/K prevents Fused Silica Super Stable Cavity-Circular Cavity length shifts, enabling precise molecular detection in atmospheric and chemical analysis.
Gravitational wave detection systems: Relies on ultra-low expansion silica and <3×10⁻¹⁵/day drift to maintain interferometer arm stability. Low surface roughness minimizes scatter, enhancing sensitivity to faint spacetime ripples from cosmic events.
Fundamental physics experiments (e.g., dark matter searches): Employs vacuum-compatible, low-drift components to eliminate environmental 干扰. Fused silica’s purity and dimensional stability ensure measurements aren’t skewed by material-related artifacts, critical for probing new physics.
