The eighteenth International Conference on Laser Spectroscopy was held on 24-29 June 2007 in Telluride, Colorado. In keeping with its rich tradition, ICOLS-07 was truly an international gathering with 173 delegates and 34 accompanying guests from 21
This symposium was a dedication to John L Hall, who was recently awarded the Nobel Prize in Physics, (report below). The symposium was a celebration of his striking career in physics and his impressive record of achievements. Papers included in this

We describe a high-performance, compact optical frequency standard based on a microfabricated Rb vapor cell and a low-noise, external cavity diode laser operating on the Rb two-photon transition at 778 nm. The optical standard achieves an instability

We propose a method for slowing, cooling and trapping Yb atoms using stimulated forces and only the 1S0 → 3P1 transition. With laser frequency chirp, our computer simulation predicts a MOT loading rate over 108 atoms/s.
