Abstract
We report observations of self-focusing and filamentation of ~3 ns laser pules in strontium (Sr) vapor. The expermental arrangement consits of a Sr vapor cell and a pulsed Nd:YAG pumped dye laser tuned to the blue of the 461 nm transition in Sr. The spatial intensity distribution of the self-focused beam has been measured at the exit window of the vapor cell by using a magnifying lens and video camera. Measurements of power dependence and scaling behavior for filament formation and shape are in good qualitative agreement with theory over a wide range of vapor densities, laser detunings, and laser powers.Citation
