Deceleration and Cooling Details
Mode-locked lasers may be the key to producing large samples of cold molecules, as discussed in a paper published this week in Phys. Rev. A (see Publications). Andrew Jayich et al. describe a method for using picosecond pulses to decelerate molecules and single photons to cool the resulting sample to sub-cryogenic temperatures. This scheme involves a technique known as Adiabatic Rapid Passage, the details of which are revealed in beautiful color plots such as the one shown here.
