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 کاملMicrofabricated saturated absorption laser spectrometer.
We demonstrate a miniature microfabricated saturated absorption laser spectrometer. The system consists of miniature optics, a microfabricated Rb vapor cell, heaters, and a photodetector, all contained within a volume of 0.1 cm(3). Saturated absorption spectra were measured with a diode laser at 795 nm. They are comparable to signals obtained with standard table-top setups, although the rubidiu...
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 کاملNonlinear absorption microscopy.
For the past two decades, nonlinear microscopy has been developed to overcome the scattering problem in thick tissue imaging. Owing to its increased imaging depth and high spatial resolution, nonlinear microscopy becomes the first choice for imaging living tissues. The use of nonlinear optical effects not only facilitates the signal originating from an extremely small volume defined by light fo...
