Efficient third-harmonic blue-violet light generation in bulk germanosilicate and Er/sup 3+/-doped germanosilicate glasses pumped at 1.319 /spl mu/m

Summary form only given. There has been a widespread interest in research and development of solid-state blue-light sources, owing to their potential applications in optical-data storage, undersea communications, and displays. In this work we report on the generation of third-harmonic 120 /spl mu/W average power light at 440 nm in bulk GeO/sub 2/-SiO/sub 2/ and Er/sup 3+/-doped GeO/sub 2/-SiO/sub 2/ glasses pumped by a Nd:YAG al 1.319 /spl mu/m.
