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)). WebDec 25, 2024 · Abstract: We proposed an improved femtosecond optical Kerr gate with double gate pulses (DOKG) using a femtosecond laser, in which an ultrashort switching time can be realized even when a relatively slow response optical Kerr medium of carbon disulfide was used.
