摘要: Phase-matched third-harmonic generation is demonstrated in a germanium-doped optical fiber. Green light at 514.4 nm generated an LP(03) mode when pump field ~1543.3 launched into the fiber fundamental LP(01) mode. The phase matching achieved for particular combination of germanium doping concentration and core diameter.
