External-Feedback Laser Cooling of Molecular Gases

Abstract

We analyze the laser cooling of a gas of polarizable particles by continuous dispersive position detection and active feedback. Microkelvin temperatures can be attained inside an optical resonator, while in free space cooling requires wavelength-size beams. The maximum cooling flux is set by the thermal Doppler width, with typical values between 100000 and 10 to the 9th power molecules per second.
