간편결제 가능The Borosilicate Rubidium Vapor Reference Cell is a high-quality reference cell designed for laser frequency stabilization and spectroscopy applications based on the optical transitions of rubidium atoms. This product provides highly reliable reference signals at the rubidium D1 (795 nm) and D2 (780 nm) transitions via Doppler-free saturation absorption spectroscopy, serving as a standard device for laser locking and transition verification in laboratory environments. The cell is filled with high-purity rubidium vapor and constructed with robust borosilicate glass, offering excellent optical performance and long-term stability for high-sensitivity optical experiments.
■ Specifications |
Filling Element : Natural Rubidium (Isotopic Ratio: ⁸⁵Rb 72.15 %, ⁸⁷Rb 27.85 %)
No Buffer Gas : Ensures natural linewidth of the rubidium transitions without broadening effects from buffer gases
Material : Borosilicate glass for high thermal stability and chemical durability
Vacuum Level : Ultra-high vacuum (UHV) condition below 10⁻⁸ Torr for minimized impurities and stable vapor environment
Shape / Volume : Inner Dimension (5 mm x 5 mm x 10 mm)
■ Manufacturing Process and Technical Reliability |
OAQ’s Reference Cell products are manufactured based on the high-purity Rb vapor cell fabrication technology validated by KRISS, KAIST, and ADD. This process offers the following key advantages:
High-Purity Cleaning and Contamination Control : The internal surfaces of the cells undergo ultrasonic cleaning followed by high-temperature baking (up to 550 °C for 24 hours) to minimize residual impurities. This process guarantees the purity of the rubidium vapor and ensures stable optical signals with long-term reproducibility.
Vacuum Purging and Gas Filling : After high-temperature baking, nitrogen purging and buffer gas filling are performed under ultra-high vacuum conditions (4.7 × 10⁻⁹ Torr). This process provides a highly controlled environment, essential for precision applications such as electric field sensing and atomic spectroscopy.
Ampoule Break-Seal Rubidium Filling Method : Rubidium vapor is introduced into the cell by breaking a pre-sealed rubidium ampoule within the vacuum system and precisely injecting the vapor into the cooled cell. This method prevents contamination during the filling process and maximizes the efficiency and purity of rubidium vapor loading.
Tip-Off Sealing (Flame Sealing Method) : The fill stem of the cell is hermetically sealed using flame tip-off sealing under high-vacuum conditions, ensuring long-term stability and preventing any external contamination from entering the cell.
■ Applications |
Laser Frequency Reference : Stable locking to rubidium D-line transitions
Doppler-Free Saturation Absorption Spectroscopy
Standard Reference Cell for Atomic Clocks, Quantum Sensors, and Atom Interferometers
Laser Tuning Verification and Educational Demonstration Equipment
■ Value Proposition & Competitive Advantage |
