The response of reverse-saturable dyes, since it is associated with electronic transitions, can be extremely fast, and consequently there have been proposals for the application of these dyes to laser mode locking, pulse shaping, and optical limiting. We recently reported that there is an important paradox concerning picosecond reverse-saturable absorption (RSA) at high In conclusion, we present several novel nonlinear optical phenomena that can accompany reverse-saturable absorption. Extended theoretical analysis accounting for the aforementioned processes enables us to produce computational fits and explanations for all the picosecond responses.
