Laser cooling of lithium using relay chirp cooling
Optics Letters, 1992We demonstrate a chirp-cooling technique that uses a laser with multiple FM sidebands to slow lithium atoms from initial velocities of as much as 1880 m/s to final velocities near zero. Compared with the use of a single sideband, this multisideband technique significantly reduces FM bandwidth requirements and provides a greater flux of slowed atoms.

Thermoelectrically Cooled GaAlAs Laser Illuminator
Applied Optics, 1970Required operating wavelengths in GaAs injection lasers have generally determined the operating temperature, preventing the use of optimum refrigeration systems. Recent advances in GaAIAs injection lasers have produced high efficiency lasers with selectable wavelengths from 0.8 microm to 0.9 microm. This paper discusses the refrigeration considerations

Laser-Cooled-Atomic Frequency Standard
Physical Review Letters, 1985The first frequency standard based on laser-cooled atoms is reported. Beryllium atomic ions were stored in a Penning trap and cooled by radiation pressure from a laser. The frequency of the $^{9}\mathrm{Be}^{+}$ $({M}_{I}, {M}_{J})=(\ensuremath{-}\frac{3}{2}, +\frac{1}{2})\ensuremath{\leftrightarrow}(\ensuremath{-}\frac{1}{2}, +\frac{1}{2})$ ground ...

It is demonstrated that He-CO and He-air-CH$sub 4$ lasers perform better when operated with liquid argon cooling at 87.3$sup 0$K than with liquid nitrogen cooling at 77.35$sup 0$K.

Il Nuovo Cimento C
We present the first successful demonstration of broadband laser cooling of positronium (Ps) atoms within the AEgIS experiment at CERN. By employing a custom-designed pulsed alexandrite laser system at 243 nm with 70 ns long pulses and enough energy to saturate the 1 $ ^3$S-2 $ ^3$P transition over a 360 GHz spectral range, we reduced the temperature ...
