Abstract

Visible wavelength lasers are much sought after for many applications. In this paper we report that significant powers at blue (46 mw), green (5 mw) and red (30 mw) are now available from Tm3+ and Pr3+-doped ZBLAN fiber lasers using very convenient pumping schemes based on the Yb3+-doped silica fiber laser
