Abstract
If a low-power cw Ar+ laser beam (similar to 50 mW) is sent horizontal ly and focused on the entrance side of a cuvette containing an absorpt ive solution, the beam fans into the lower half of the cuvette instead of propagating through and forming self-phase-modulation fringes. We call this phenomenon self-beam fanning, which has been observed in sev eral organic solutions. We present here several experimental results a nd a descriptive model of the phenomenon.
