Abstract: | A very simple technique, by which both the magnitude and
the sign of nonlinear refraction can be determined through using
only one single pulse and beam with a phase object, is presented.
Using this technique, only the transmittance of an aperture in the
far field is investigated. We study the nonlinear refraction of the
carbon disulfide by using the presented technique with 21~ps pulses
at a wavelength of 532~nm as a test. |
