Abstract

When the ultrashort pulse laser power is higher than its self-focusing critical power in optical me-dia, the laser will form plasma filament due to the dynamic balance between the nonlinear Kerr

self-focusing and plasma defocusing effects. The filament has a very broad application due to its unique advantages in many research fields. In the different fields of the femtosecond laser fila-mentation, the conical lens, also called axicon, is often chose as a focal element which has a very important property of long focal depth. This paper discusses the research progress of femtosecond laser filamentation in solid, liquid and gas by using concial lens respectively, and summarizes the characteristics of filamentation in different nonlinear media, which provides a helpful reference for the application of the conical lens.
