Abstract

Simultaneous three-photon excited stimulated emission at (cavityless lasing) ∼610 nm has been achieved in an organic chromophore solution pumped by ∼1.5-μm ultrashort coherent radiation. The stimulated emission can be observed only in the forward and backward directions and is characterized by its high directionality and spectral narrowing. The divergence angle for the backward stimulated emission is considerably smaller than that for the forward stimulated emission, which resembles optical phase conjugation.
