The invention provides a surface luminescent semiconductor laser capable of converting frequency at a high speed and stably controlling laser polarization direction. The laser comprises a semiconductor base plate, a lower mirror layer, an active layer, an upper mirror layer, a resonator, an insulation layer and electrodes, wherein the lower mirror layer is formed above the semiconductor base plate; the active layer is formed above the lower mirror layer; the upper mirror layer containing an oxide layer is formed above the active layer; the lower mirror layer, the active layer and the upper mirror layer are sequentially deposited; the resonator with a partial countertop shape is arranged above a special position at the height direction; the insulation layer covers the side of the countertop part of the resonator and the upper part of the non-countertop part of the resonator; and the electrodes are respectively wired above the upper mirror layer and below the semiconductor base plate. The thickness of the part formed on the insulation layer of the side of the countertop part of the resonator is comparably thicker than that of the other parts along the height direction of the countertop part.
