Inducing q-switching operation at 1-micron all-fiber laser via lutetium oxide film saturable absorber
We demonstrated a rare-earth element of lutetium oxide (Lu2O3) as a passive saturable absorber (SA) for generating Q-switching operation laser at 1-micron region. The laser cavity is all-fiber ring configuration with a single-clad ytterbium-doped fiber as a gain medium. Under dropcasting fabrication...
