Standing wave probe field

A weak cw circularly polarized probe beam is applied to the sample and together with its reflection off the mirror creates a standing wave probe field which monitors and when the probe wavelength is matched to the pump wavelength. Solving Maxwell s Equations for the probe field inside the sample volume with a modulated adsorption constant and index of refraction, for the case where yields a coupled wave equation for the inci-... 

It is interesting to observe that response differences between the coatings decrease when the frequency is increased. This is probably connected with the respective values of the wavelength and of the thickness of the layer in which absorption takes place which was estimated to be around 120 pm thick. The influence of the relative size of the probe compared to the wavelength was studied in standing waves fields [33]. As expected, maxima and minima were observed for the probe response. The ratio of the temperature rise at pressure maxima and minima... 

Other probe designs have been described in the literature [40-49], Almost all of these systems can detect standing waves and local field distributions.

We would like to find out the effeet of the probe detuning on the atom loealization. Because of the periodicity of the standing-wave field, we only study the varianee of F(x) in the subwavelength domain( -ir [Pg.41]

The probe absorption is now related on the directions x and y. The conditional position probability of finding the atom at a precise position in the standing-wave field, after the probe absorption, is then determined by the filter fimction... 

Av by the pump wave (hole burning), and the successive probing of this depletion by a second wave. In the standing wave of the second zone the nonlinear saturation by the pump wave depends on the relative phase between the molecular dipoles and the field. This phase is determined by the starting point (0,Zj ) in the first zone and by the transverse velocity component v. ... 

The cold atoms may eventually be spatially captured in a three-dimensional standing wave field [13.18]. The motion of the atoms is due to the combined action of spontaneous and induced light pressure. If the light frequency is tuned below resonance, the atoms are cooled by the spontaneous forces until their velocities decrease below the critical value. Due to the induced force they undergo oscillatory motions around the potential minima of the three-dimensional standing wave field. The observation of this motion can be performed with a probe laser, tuned to a transition other than that used for cooling [13.19].
