Abstract
We present a simple way to achieve single-frequency operation by using a fiber-coupled diode butt-coupling-pumped Nd:YVO4 laser in a flat-fl at cavity. Single-mode outputs of 620 and 260 mW for fundamental and s econd-harmonic wavelengths were obtained when the laser was pumped by an 1100-mW fiber-coupled laser diode. Experimental results show that t hermal effects provide not only a stable resonator with a good overlap of laser mode and pump size but also enhance single-frequency perform ance.
