Saturable Absorption of Copper Nanowires in Visible Regions for Short-Pulse Generation
Published 2016-01-01Get full textA copper-nanowire (CuNWs)-based saturable absorber (SA) is utilized as a new Q-switcher for pulsed operations in visible regions. The plasmon resonance effect of CuNWs contributes to inducing the saturable absorption property. By incorporating the CuNWs-based SA into a red praseodymium <inline-fo...

Passive Q-Switching of a Diode-Pumped Pr:LiYF<sub>4</sub> Visible Laser Using WS<sub>2</sub> as Saturable Absorber
Published 2016-01-01Get full textQ-switched laser operation of a blue-diode-pumped Pr:LiYF<sub>4</sub> laser is demonstrated at 640 nm for the first time by using a tungsten disulfide (WS<sub>2</sub>) nanosheet material as a saturable absorber. Stable laser pulses of 630 ns are obtained with a pulse repetiti...
