Saturated Absorption Spectroscopy
You will use a tunable diode laser to carry out spectroscopic studies of the rubidium atom. You will measure the Doppler-broadened absorption profiles of the D2 transitions at 780 nm and then use the technique of saturated absorption spectroscopy to improve the resolution beyond the Doppler limit and measure the nuclear hyperfine splittings, which are less than 1 ppm of the wavelength. A FabryP...
متن کاملDoppler-Free Saturated Absorption Laser Spectroscopy
The fundamentals of Doppler-free saturated absorption spectroscopy were explored for a rubidium sample. Two probe laser beams from a 780-nm diode laser were directed through the Rb cell, and one of them was crossed by a pump beam in the opposite direction. Because of the changes in the ground-state population caused by the pump beam, subtraction of the intensity signals from the two probe beams...
متن کاملSaturated-absorption cavity ring-down spectroscopy.
We report on a novel approach to cavity ring-down spectroscopy with the sample gas in saturated-absorption regime. This technique allows us to decouple and simultaneously retrieve the empty-cavity background and absorption signal, by means of a theoretical model that we developed and tested. The high sensitivity and frequency precision for spectroscopic applications are exploited to measure, fo...

متن کاملMeasurement of neutral flow velocity in an ECR plasma using tunable diode laser LIF spectroscopy combined with saturated absorption spectroscopy
The radial flow of neutral particles in an electron-cyclotron-resonance (ECR) argon plasma has been measured by using a newly developed high resolution laser induced fluorescence (LIF) measurement system. The flow velocity is determined by the Doppler shift of the LIF spectrum. A very high accuracy calibration of an excitation laser has been achieved by installing a saturated absorption spectro...
