Resolved-sideband Raman cooling of an optical phonon in semiconductor materials by Zhang, Jun, Zhang, Qing, Wang, Xingzhi, Kwek, Leong Chuan, Xiong, Qihua

“…Recently, by using the electrostrictive forces of light, spontaneous Brillouin cooling and stimulated Brillouin excitation of acoustic modes of the whispering-gallery-type resonator have been demonstrated. The laser cooling of specific lattice vibrations in solids (that is, phonons) proposed by Dykman in the late 1970s, however, still remains sparsely investigated. …”

The formation of ultracold rubidium molecules using ultrafast photoassociation by McCabe, D, David McCabe

“…The establishment of robust laser-cooling techniques for the formation of ultracold atoms has provided a test-bed for low-temperature science, with scattering events changing character from incoherent thermal interactions to coherent quantum mechanical events. …”

Periodically driven atomic systems by Trypogeorgos, D

“…Periodic driving is ubiquitous in most techniques used in atomic physics, be it laser cooling, ion trapping or AC magnetic fields. An in-depth understanding of the behaviour of such systems can be provided through Floquet theory which will develop as a central theme in the following chapters.…”

Towards an imaging lattice for magnetically trapped atoms by Owen, E

“…In most cases, the excitation light frequency is chosen so that there is a concomitant laser cooling effect. In existing implementations of an imaging lattice the preceding manipulation stage has used optical trapping and manipulation. …”

The Design, Fabrication and Characterization of a Transparent Atom Chip by Ho-Chiao Chuang, Chia-Shiuan Huang, Hung-Pin Chen, Chi-Sheng Huang, Yu-Hsin Lin

“…An area on the chip was reserved for the optical access, so that the laser light can penetrate directly through the glass substrate for the laser cooling process. Furthermore, since the thermal conductivity of the glass substrate is poorer than other common materials for atom chip substrate, for example silicon, silicon carbide, aluminum nitride. …”
