Abstract

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

摘要

在掺锗光纤中实现了相位匹配的三次谐波产生。当泵浦光以基本 LP(01)模式在光纤中传输时，在 ~1543.3nm 附近的泵浦场可以产生 514.4nm 的绿光。对于特定的掺锗浓度和光纤芯径组合，可以实现相位匹配。
