Abstract
The influence of fluorescence amplification and parasitic modes on the gain characteristics of a laser amplifier is investigated experimentally for a YAG:Nd rod. Possibilities of suppressing parasitic modes are tested. By cutting small grooves into the cylindrical surface of the rod the gain is shown to be improved by a factor 2.4 with respect to a ground rod.Keywords
