A self-injected, diode-pumped, solid-state ring laser for laser cooling of Li atoms.
We have constructed a solid-state light source for experiments with laser cooled lithium atoms based on a Nd:YVO4 ring laser with second-harmonic generation. Unidirectional lasing, an improved mode selection, and a high output power of the ring laser were achieved by weak coupling to an external cavity which contained the lossy elements required for single frequency operation. Continuous freque...
متن کاملSolid-state Laser Cooling of Ytterbium-doped Tungstate Crystals
Anti-Stokes fluorescence can be used to cool a material if its radiative quantum efficiency is nearly unity. Until recently, the only solid which had shown net cooling was an ytterbium-doped heavy metal fluoride glass. Reasons for the lack of success with other materials include energy transfer to unwanted impurities, trapping of the fluorescence by internal reflection and reabsorption, and non...
متن کاملConstruction of a solid-state RGB laser
In this master thesis project, a solid-state red-green-blue (RGB) laser was built. The project consisted of two parts. In the first part, an actively Q-switched diode-pumped solid-state laser was constructed. As laser gain medium, a Nd:YVO4 crystal, which lased at 1064 nm, was used. The Q-switch was a home built electrooptic modulator based on two RTP crystals. The modulator had a shortest rise...
متن کاملTransverse laser cooling of a velocity-selected sodium atomic beam
The transverse velocity distribution of a sodium atomic beam, laser cooled in one dimension, has been measured with sub-recoil resolution. A velocity-selective detection system was employed to separate the longitudinal and transverse velocity components to provide a direct measure of the transverse velocity distribution. The effects of varying the cooling laser intensity and detuning on the der...
متن کاملLaser Cooling of Semiconductors
Optical irradiation accompanied by spontaneous anti-Stokes emission can lead to cooling of matter, a phenomenon known as laser cooling or optical refrigeration proposed in 1929 by Peter Pringsheim. In solid state materials, the cooling is achieved by annihilation of lattice vibrations (i.e., phonons). Since the first experimental demonstration in rare-earth doped glasses, considerable progress ...
