2. Q-switching and efficient harmonic generation from a single-mode LMA photonic bandgap rod fiber laser

Author

Laurila, Marko, Saby, Julien, Alkeskjold, Thomas T., Scolari, Lara, Cocquelin, Benjamin, Salin, Francois, Broeng, Jes, Lægsgaard, Jesper, Laurila, Marko, Saby, Julien, Alkeskjold, Thomas T., Scolari, Lara, Cocquelin, Benjamin, Salin, Francois, Broeng, Jes, and Lægsgaard, Jesper

Abstract

We demonstrate a Single-Mode (SM) Large-Mode-Area (LMA) ytterbium-doped PCF rod fiber laser with stable and close to diffraction limited beam quality with 110W output power. Distributed-Mode-Filtering (DMF) elements integrated in the cladding of the rod fiber provide a robust spatial mode with a Mode-Field-Diameter (MFD) of 59 mu m. We further demonstrate high pulse energy Second-Harmonic-Generation (SHG) and Third Harmonic Generation (THG) using a simple Q-switched single-stage rod fiber laser cavity architecture reaching pulse energies up to 1mJ at 515nm and 0.5mJ at 343nm.
