Abstract

Abstract

By utilizing a fiber-coupled laser diode emitting at a wavelength of around 976 nm as a pump source and a Yb:CaYAlO₄ crystal with a Yb³⁺ ion doping concentration of 1.5at.% and a thickness of 2 mm as the gain medium, a scheme of laser diode-pumped Yb:CaYAlO₄ for passively Q-switched pulsed lasers using a semiconductor saturable absorber mirror(SESAM) is proposed. By reasonably designing the resonant cavity, a stable passively Q-switched pulsed output is achieved. Furthermore, the influence of the pump power on the pulse repetition rate, pulse width, single pulse energy and peak power are analyzed.
