Ultra-precision Machining Process: Achieving Nanoscale Smoothness
Our Super-smooth Optical Ultra-stable Cavity is manufactured using advanced super-precision processing technologies, including chemical mechanical polishing (CMP) and ion beam figuring (IBF). The cavity’s optical surfaces achieve an ultra-low roughness of <0.1nm RMS, eliminating micro-defects that could affect resonance quality. Surface flatness is controlled within λ/10 @632.8nm, ensuring consistent optical performance across the entire cavity. The cavity length is strictly controlled within ±0.001mm, with parallelism control within <3 arc seconds to optimize resonance efficiency. Edge chamfering (0.3-0.8mm×45°) is applied to prevent chipping and reduce stress concentration during mounting and use.
Core Performance Advantages: Suitable for High-end Precision Scenarios
Ultraopto’s Super-smooth Optical Ultra-stable Cavity boasts exceptional frequency stability with an Allan variance as low as 1×10⁻¹⁵, meeting the stringent requirements of atomic clocks and quantum computing. The cavity exhibits high finesse (up to 15,000) due to ultra-high mirror reflectivity (>99.97%), enabling sharp resonance peaks for precise laser locking via Pound-Drever-Hall (PDH) technology. Its super-smooth surfaces minimize scattering loss and thermal noise, while the advanced coating technology enhances reflection performance and environmental durability. The cavity features low acceleration sensitivity (<5×10⁻¹¹/g), minimizing vibration-induced noise, and supports fundamental mode (TEM₀₀) operation, suppressing higher-order transverse modes for pure frequency reference signals.
Full-scenario Application Coverage: Empowering High-end Optical Equipment
Our Super-smooth Optical Ultra-stable Cavity is widely applied in cutting-edge scientific research and industrial fields. In laser stabilization systems, it serves as a frequency reference to lock narrow-linewidth lasers for gravitational wave detection and optical communication. For atomic clocks (Yb, Sr, Ca-based), it provides the stable frequency reference required for ultra-precise timekeeping. In precision spectroscopy and optical frequency metrology, it enables high-resolution spectral analysis and optical frequency comb locking. The cavity also finds use in quantum computing, laser radar (LIDAR) with long coherence time, and fiber sensing systems, delivering reliable ultra-stable performance for the most demanding applications.
