In 1965, many laboratories attempted to understand gain anomalies observed in stimulated raman scattering. There was fierce competition and several groups arrived independently at the conclusion that self-focusing was the cause for most of the so-called “anomalies”. This note describes our experimental demonstration of this fact. The references show that this subject was a “hot topic” at that time.
