Gold Nanorods as Single and Combined Saturable Absorbers for a High-Energy $Q$-Switched Nd:YAG Solid-State Laser

open access: yesIEEE Photonics Journal, 2015
Gold nanorods (GNRs) with surface plasmon resonance peak at 1063.8 nm were fabricated and experimentally exploited as the single and combined saturable absorber (SA) in a Q-switched Nd:YAG laser for the first time. In the situation using GNRs as a single
