Abstract

Kigre is developing new rare-earth-doped glass fiber laser materials specifically for use in multiple clad and multiple core LMA and super mode (guided wave) fiber laser constructs. In this work we describe new end-pump double clad fiber laser designs fabricated from high performance phosphate laser glass compositions. One DC LMA fiber is doped with erbium/ytterbium for 1.54μm laser emission. Another DC LMA fiber is doped with ytterbium for 1.03μm laser emission. A third DC multiple core "supermode" fiber is doped with neodymium for 1.053μm laser emission. Initial fiber laser performance data is presented. The rebium/ytterbium & ytterbium only doped fibers are end-pumped at 940/975nm with 40-Watt fiber coupled laser diodes. The neodymium-doped fiber is end-pumped with an 808nm 40-Watt fiber coupled laser diodes. Design and performance data for new side-pumped, highly doped phosphate DC LMA fiber laser architectures are presented.
