| Abstract Title: |
W38 - Diode-Laser Spectroscopy |
| Abstract: |
The tunable diode laser has revolutionized optics and atomic physics, by providing a reliable source of narrowband light which is easily tunable across an adequate range of the spectrum. TeachSpin's Diode Laser Spectroscopy system shows off the capabilities of such a system on a tabletop, using everyone's favorite atomic resonance, the 780-nm D2 transition in rubidium vapor. Because of the intensity available f a laser source, it is simple to display non-linear phenomena such as (Doppler-free) saturated absorption spectroscopy, coherent population trapping, and nonlinear Faraday rotation, in set-ups easily replicated by students.
Participants will:
• Observe and tweak the alignment of invisible beams of 780-nm monochromatic radiation
• See the fluorescence from Rb vapor when the laser is properly tuned
• Relate the structure of resonances observed to the isotope and hyperfine structure of the atomic transition
• Follow the beams which permit pump-probe Doppler-free spectroscopy
• See the sub-Doppler upper-state hyperfine splittings of a transition |
