Abstract
The advantages of using the method of laser coloration for investigation of specific features of filamentation in homogeneous transparent dielectrics are described. The results of several experiments conducted with a lithium fluoride crystal by this method are presented. The possibility is shown of obtaining data on the structure of the light field in a filament formed by a single laser pulse and processing them at a substantially later time after the experiment, which is not available by using other methods, allowed observing a plasma-free regime of filamentation, detecting single-cycle light bullets, and demonstrating their robustness.
