| Abstract Title: |
Diode-laser Spectroscopy A |
| Abstract: |
Modern diode-laser technology makes it possible to realize on a tabletop the ideal of a monochromatic, yet tunable, source of collimated light waves, in the form of a laser beam of many mW of power, and well under 10 MHz of optical linewidth, near a frequency of 384 million MHz (near wavelength 780 nm in the near-infrared). This laser radiation can resonate with an optical transition in atoms of rubidium, conveniently available in the vapor phase in glass cells near room temperature. The result is a system in which the fundamentals of the resonant interaction of light and atoms can be studied in exquisite detail.
Participants will see, at level A, Introduction to Diode-laser spectroscopy:
- how to activate a (temperature-stabilized) diode-laser system; how to detect the (invisible) beam, and how to reach threshold and operating points of the laser
- how to make the laser beam interact with an atomic vapor, and how to image the fluorescence that occurs when the laser is properly tuned
- how to use a piezo-electric drive to tune the diode-laser source, and how to display the effect of 'scanning' the laser frequency over the atomic resonance(s)
- how to use a non-imaging photodetector to display the absorption (as well as the fluorescence) by the atomic sample
- how to use a slow scan to show the absorption and fluorescence are correlated properties
- how to use the spectroscopy system to infer the 'Doppler width' of the atomic transitions observed
