Multichannel laser cooling of atoms using an optical frequency comb
Optical frequency combs (FCs) have become an unavoidable source of light in 
applications ranging from metrology and high-resolution spectroscopy to 
precision ranging and calibration of atomic spectrographs. In recent years, 
the applications of FCs have expanded to laser cooling and trapping of atoms 
and ions, and quantum communication. In this talk, I will present our results 
on the FC-atom interaction in the case when the cold atoms are in free space 
or are placed inside a high-finesse optical cavity. For atoms in free space, 
FC cooling of neutral atoms [1], and simultaneous dual-species FC cooling [2] 
is demonstrated. For atoms placed inside a high-finesse optical cavity, a 
multi-frequency dispersive interaction is observed [3]. As a result of 
dispersive interaction, the squeezing and broadening of atomic distribution 
in time-of-flight images is measured.Our results contribute to the 
development of novel laser cooling techniques using a single frequency comb 
source.[1] N. Šantić, D. Buhin, D. Kovačić, I. Krešić, D. Aumiler, and T.
