In addition, the third harmonic technique is employed to compensate for the low frequency inadequacy. Lastly, the total phase S(r, z), like the low and high frequency elements, modulates the light field. Therefore, the option of Equation (ten) is expressed as [28] E(r, z + z) = exp exactly where expi 2k z+z zi 2kz+z zd exp[iS(r, z)] E(r, z),(19)d is triggered by vacuum diffraction.3.2.

For the 2.0 MHz linewidth laser, its intensity distribution is expressed as Equation (five). The total intensity of your laser is taken as I = 150 W/m2 . It really is assumed that sodium atoms are excited each 32 ns as a consequence of the cycle time of excited states. The tens of nanoseconds inside the ascending stage are ignored just before steady states. For the 0 MHz laser, the normalized distributions of sodium atoms just after recoil are simulated at t = 10 , 20 , and 35 as in Figure 2. So that you can study the effects of linewidth broadening around the mitigation of recoil, the linewidth with the continuous wave laser is taken to become two.0 MHz in Equation (five). Following t = 10 , 20 , and 35 , the normalized distributions on the sodium atoms are presented in Figure 3.Figure 2.

Normalized distributions of sodium atoms with linewidth broadening at t = ten , 20 , and 35 .From Figure two, one can see that recoil outcomes in the accumulation of sodium atoms at larger and greater Doppler shifts as time goes on. Compared with Figure two, after linewidth broadening is employed, the peaks of recoil drastically drop in Figure four, plus the corresponding 3 sodium atomic distributions are coincident. Along with this, the laser intensity also influences recoil, as is shown in Figure four. Using the exact same linewidth broadening process as the above, following t = 35 for I = 50 W/m2 , one hundred W/m2 , and 150 W/m2 , the situations of mitigated recoil are shown in Figure five.Figure 4.
