We demonstrate a simple way to achieve single-frequency operation by using fiber-coupled diode-pumped Nd:YVO<sub>4</sub>/KTP green lasers in a short standing-wave linear cavity. A single-mode output with 3.2-W green power was generated with a 12.6-W pump power corresponding to a conversion efficiency of 25.4%. The single-mode operation was obtained through the combined action of the anisotropic emission cross section of Nd:YVO<sub>4</sub> and the KTP crystal acting as a birefringent filter.
