ABSTRACT:
We aim to examine double resonance of Rb vapor cell via synthesizing the input 10 MHz frequency as standard atomic clock devices. For this purpose, we use the Voltage Controlled Oscillator onto the synthesizer and record double resonance between optical and microwave pumping. Our results show that the fabricated synthesizer, whose applied frequency is locked to a target frequency, can generate efficient coupling between these two main resonances in atomic media.
