Polarization-dependent Rabi frequency beats in the coherent response ofTm3+in YAG

Long-time-storage mechanism for Tm:YAG in a magnetic field

“…There are 8 formula units per cubic unit cell in YAG, which gives 24 different sites for the Tm ions but only 6 different orientations of the sites. 8,9 Tm has a nuclear spin of 1͞2, which gives no zero-f ield hyperf ine splitting of the levels. When a magnetic f ield is applied, both the ground and the excited states are split into two Zeeman-type levels through the coupling of the nuclear magnetic moment to the f ield.…”

Numerical modeling of optical coherent transient processes with complex configurations—I. Angled beam geometry

“…The fully coupled Maxwell-Bloch equations are required to adequately study the problem of the laser field propagation and the coherent transient processes, especially in the thick media [6,7]. The coherent effects of light interacting with an ensemble of inhomogeneously broadened two-level atoms is governed by Bloch equations, where the electric field acts as a source to drive the atomic dipoles.…”

Optical solitons in periodic media with resonant and off-resonant nonlinearities

“…Cryogenic conditions in such structures can strongly extend the dephasing time T 2 and thus the soliton's or LB's lifetime, well into the µsec range (Greiner, Boggs, Loftus, Wang and Mossberg [1999]), which would greatly facilitate the experiment. The construction of suitable structures constitutes a feasible experimental challenge.…”

“…5 -Ch. 7 is to use thin layers of rare-earth ions (Greiner, Boggs, Loftus, Wang and Mossberg [1999]) embedded in a spatiallyperiodic semiconductor structure (Khitrova, Gibbs, Jahnke, Kira and Koch [1999]). The two-level atoms in the layers should be rare-earth-ions with the density of 10 15 − 10 16 cm −3 , and large transition dipole moments.…”
