(a) Beam intensity profile on the exit surface of the Kerr medium for the super-Gaussian and the Gaussian cases. The common logarithm of the intensity is taken. (b) The evolution of Imax from the rear surface of the nonlinear medium for the defect of the super-Gaussian case, Gaussian case, high pass of the super-Gaussian case, low pass of the super-Gaussian case, high pass of the Gaussian case, and low pass of the Gaussian case. To observe the corresponding position of the peak, the data is normalized. The top view of the variation of the transversal beam intensity distribution with the propagation distance for (c) the high pass of the super-Gaussian case, (d) the low pass of the super-Gaussian case, (e) the high pass of the Gaussian case, and (f) the low pass of the super-Gaussian case. The common logarithm of the intensity is taken in (c–f).

Nonlinear hot image is one of the key elements that limit the output performance of high-power laser systems. In most hot-image researches, only one hot image peak is observed in the conjugate position for a single defect. Generally, multiple hot image peaks occur for multiple defects or cascaded nonlinear media. However, a new phenomenon is found...
