We are reporting on S i O 2 ‐ A l 2 O 3 ‐ L a 2 O 3 glasses—with and without Y b 2 O 3 —suitable for nonlinear and fiber laser applications. We will also be presenting successful supercontinuum generation and fiber laser operation around 1060 nm in step‐index fibers. We optimized the glass compositions in terms of thermal and optical requirements for both a high L a 2 O 3 and Y b 2 O 3 concentration and good compatibility with a silica cladding. We also produced bulk samples, unstructured fibers, and structured fibers with a S i O 2 ‐ A l 2 O 3 ‐ L a 2 O 3 core and silica cladding for this purpose.
