In the case of a surface-emitting semiconductor laser having a semiconductor chip (1), a first resonator mirror (4) and at least one further resonator mirror (8) which is arranged outside the semiconductor chip (1) and, together with the first resonator mirror (4), forms a laser resonator with a resonator length L, and having a pump laser (10) which optically pumps the semiconductor laser (1) by injecting pump radiation (14) at a pump power into the semiconductor chip (1), the pump power is modulated with a modulation frequency fP, and the resonator length L is matched to the modulation frequency fP.
