The 1PW transmit power of the atom A corresponding to the launch 1.2 cavity photon. If during the cooling emission values of less than cavity value <n0,> 10%. For the theoretical analysis of the fixed coupling coefficient g curve (solid line) lead to g = 0.83 (12) × g, 0 and the remaining Stark frequency shift? S / 2π = 0.7 (1.3) MHz, Cavity emission (blue dotted line) for reference. - 16 - East China University of Technology thesis single-atom laser imprisoned Figure 12-cavity transmission power and the detuning of the relationship between zero detuning, the curve with the previous red detuned dipole trap experiments in the norm spectrum is the same. The obvious difference is that the red trap atoms in the resonance frequency shift is twice that of the ground state well depth in the central trap caused the atomic transition frequency is close to the cavity resonance frequency.It is another remarkable and attractive feature for this kind of green laser pointer
Cavity imprisoned many of the real-time measurement of the atomic number and the experimental results of quantum information science (QIS) communication protocol program requirements imprisoned a number of atoms in the same cavity, so that through the cavity - strong coupling between the various atoms within the state of the quantum wiring. Therefore, to determine the coupling cavity atomic number of the experiment is the first step in achieving a variety of goals in QIS. 2006, Rempe group in the three-dimensional cavity atom cooling experiments in atomic number measurement scheme shown in Figure 14, they measured the scattering of photons to determine the cavity atomic precision number. The small signal changes pointed out that the coupling of the cavity and atomic almost unchanged when the atom is missing, the signal ladder. Here will introduce the dust proof characteristic
A circularly polarized light to stimulate the TEM00 mode, In the experiment, the cavity frequency with a different cavity longitudinal mode (785nm) resonance of the second laser stability. Stability of the laser is weak, does not affect the atomic motion. Shipped nearly resonant pumping light dipole induction in a rapid oscillation of the atoms in the cavity axis direction, resulting in a cavity cooling and the spread of interesting interactions. For the realization of the feedback loop requires the use of appropriate electronics to reflect changes in the cavity transmission rate. Through the cavity transmission intensity using a photon counter to detect the overflow from the cavity mode photon detection efficiency is about 10%. Photon number by the computer records and at the same time give a count rate - voltage converter (CRVC). CRVC signal through a 10 KHz low-pass filter, and used as a trigger and feedback electronics. There is a dust-proof switch at the most front of the body of green laser pointer
