110 5 Discussion <strong>of</strong> the Experimental Results<br />

Fig. 5.12: 3D representation <strong>of</strong> the recorded <strong>ESFADOF</strong> transmission hysteresis,<br />

when incre<strong>as</strong>ing the pump power: The upper part <strong>of</strong><br />

the figures represent the P-polarization <strong>of</strong> the <strong>ESFADOF</strong> output<br />

PBS and the lower part its S-polarization. The cell temperature<br />

w<strong>as</strong> T <strong>ESFADOF</strong> = 165.5 ◦ C and a magnetic field strength<br />

<strong>of</strong> B z = 270 mT h<strong>as</strong> been applied to vapor cell I. The pump<br />

power P Pump h<strong>as</strong> been changed adiabatically, while keeping the<br />

linear polarized pump beam ∆ν P = −1.76(3) GHz detuned from<br />

the 5S 1/2 → 5P 3/2 transition center. The <strong>ESFADOF</strong> transmission<br />

spectra collapse at P Pump = 376(1) mW after adiabatically<br />

incre<strong>as</strong>ing the pump power and the maximum <strong>ESFADOF</strong> transmission<br />

drops from 19.71(1)% at P Pump = 349 mW to 4.77(1)%.<br />

A 2D plot representation <strong>of</strong> the S-polarization can be found in<br />

Fig. 5.14.
