Observation of two-photon emission from semiconductors
... complementary wavelength photons with the suppression of the rest of the spectrum. Similar results are shown for GaInP/AlGaInP QWs, and a photon-coincidence experiment verifies the simultaneity of the TPE. In our first experiment, we optically pumped GaAs with a 100-mW continuous-wave 514-nm argon l ...

Generation of a dark hollow beam by a four
... density of cold atom gas from a standard optical molasses[16] is at 1011~1014/cm3 order of magnitude, so this small volume optical dipole trap can realize single atom trap. Many atoms trapping condition can be obtained when illuminated by a laser beam first, which forms an atomic lens optical field ...

... Does a single atom’s motion obey Newton’s laws? Have students share their observations and contrast them to the discussion of Brownian motion on page 2. Have students start to hypothesize how both Brownian motion and Newton’s laws can be accurate. After completion of Part 2 of the activity: Mode ...

Laser spectroscopy and quantum optics
... frequency chains reaching into the visible spectrum. Traditional harmonic laser frequency chains are large and complex, and they are typically designed to measure just one particular optical frequency. In essence, such a chain synthesizes a high frequency, starting from a microwave Cs atomic clock, ...

Coherent manipulation of atoms with standing light waves
... The foremost goal of atom optics is to manipulate atomic waves coherently. This can facilitate the creation of atom interferometers, atom microscopes, high resolution atom lithography, and the incorporation of coherent atomic center-of-mass manipulation within an environment where internal atomic co ...
