We experimentally demonstrate a one-color two-photon transition from the $5\mathit{S}_{1/2}$ ground state to $6\mathit{S}_{1/2}$ excited in rubidium (Rb) vapor using continuous wave laser at 993 nm. The Rb contains both isotopes ($^{85}$Rb and $^{87}$Rb) their natural abundances. electric dipole allowed transitions are characterized by varying power polarization of excitation laser. Since optical setup is relatively simple, energies levels impervious stray magnetic fields, this an attractive...

We demonstrate a two-photon transition of rubidium (Rb) atoms from the ground state (5$S_{1/2}$) to excited (4$D_{5/2}$), using home-built ytterbium (Yb)-doped fiber amplifier at 1033 nm. This is first demonstration an atomic frequency reference nm as well one-colour for above energy levels. A simple optical setup presented fluorescence spectroscopy, which useful stabilization broad class lasers. spectroscopy has potential applications in laser industry reference, particularly Yb-doped also...

The stabilization of lasers to absolute frequency references is a fundamental requirement in several areas atomic, molecular and optical physics. A range techniques are available produce suitable reference onto which one can 'lock' the laser, many depend on specific internal structure or sensitive laser intensity noise. We present novel method using modulation an acousto-optic modulator's carrier (drive) signal generate two spatially separated beams, with difference only few MHz. These beams...

Abstract Here we report of a design and the performance an optimized micro-fabricated conveyor belt for precise adiabatic transportation cold atoms. A theoretical model is presented to determine optimal currents in conductors used transportation. We experimentally demonstrate fast Rubidium ( 87 Rb) atoms with minimal loss heating as few three conductors. This novel multilayered structure fabricated aluminium nitride AlN ) because its outstanding thermal electrical properties. demonstration...

We describe a dynamic magneto-optical trap (MOT) suitable for the use with vacuum systems in which optical access is limited to single window. This technique facilitates long-standing desire of producing integrated atom chips, many are likely have severely restricted compared conventional chambers. 'switching-MOT' relies on synchronized pulsing and magnetic fields at audio frequencies. The trap's beam geometry obtained using planar mirror surface, does not require patterned substrate or...

We describe the application of displaced, or misaligned, beams in a mirror-based magneto-optical trap (MOT) to enable portable and miniaturized atom chip experiments where optical access is limited single window. Two different geometries beam displacement are investigated: variation on well-known 'vortex-MOT', other novel 'hybrid-MOT' combining Zeeman-shifted purely scattering force components. The geometry obtained similar mirror-MOT, using planar mirror surface but with magnetic field more...
