124 W average output power at 540 nm by second harmonic generation in a MOPA-system with fiber phase conjugator

Abstract

Generation of higher harmonics with high average output power is necessary for numerous applications in industry and science. Particularly pulsed driven solid state lasers based on neodymium doped active media are powerful sources for highly efficient frequency conversation. In this paper, SHG in a MOPA system with fiber phase conjugate mirror is demonstrated. An average output power of 124 W is achieved at 540 nm.
