ATOMIC OSCILLATOR - A simplified explanation of the abstract
This abstract first appeared for US patent application 18200850 titled 'ATOMIC OSCILLATOR
Simplified Explanation
The present invention is an atomic oscillator that utilizes two excitation lights and an alkali metal atom gas cell to measure the resonance frequency of the gas.
- The atomic oscillator includes a light generator that produces two excitation lights.
- These two excitation lights are applied to an alkali metal atom gas cell with a frequency difference that can be adjusted.
- A detecting unit is used to measure the amount of transmitted light that passes through the gas cell.
- Based on the detected amount of transmitted light, a control unit measures the resonance frequency of the alkali metal atom gas.
- The control unit then adjusts the intensity ratio of the two excitation lights applied to the gas cell based on the measured resonance frequency.
Original Abstract Submitted
An atomic oscillator according to the present invention includes: a light generator configured to generate two excitation lights; an alkali metal atom gas cell to which the two excitation lights are applied with a frequency difference therebetween being changed; a detecting unit configured to detect a light amount of a transmitted light having passed through the alkali metal atom gas cell; and a control unit configured to measure a resonance frequency of an alkali metal atom gas based on the detected amount of the transmitted light and control an intensity ratio of the two excitation lights applied to the alkali metal atom gas cell based on the measured resonance frequency.
