Webthe observed Kerr efficiency of the quartz and SFL-6, respec-tively. The Kerr efficiency follows a xth power law of the gate intensity as shown by the broken lines; the value of x for the quartz is 2.4 and that for the SFL-6 is 2.0. For the same gate intensity, the Kerr efficiency of the SFL-6 is 60–80 times larger than that of the quartz. WebMar 21, 2012 · For optical Kerr gate measurements the two-beam setup is slightly modified. The energy in one of the paths is reduced to ∼6 μJ so that this beam path acts as a probe beam and the other beam path acts as a pump beam. In the probe beam path a λ /2 plate is placed before the sample and an analyzer is located after the sample (Fig. 1 (d)).
