Abstract

Abstract: In this paper, based on Au Nanorod saturable absorber(SA), laser characteristics of LD endpumped passively Qswitched Nd:YASG laser were demonstrated. By controlling the lengthdiameter ratio of the Nanorod, the longitudinal surface plasmon resonance (SPR) absorption peak was located at 1 062 nm. Therefore, passively Qswitching could be achieved by using them. Furthermore, stable passive Qswitched pulses with an average output power of 14 mW was obtained at the pump power of 4.9 W. The minimum pulse width of 944.1 ns was achieved at the pulse repetition rate of 100.1 kHz. The experimental results prove that Au Nanorod is a promising SA for solidstate lasers.

Key words: Nd:YSAG crystal, passively Q-switched, Au Nanorod
