We present a long term stable single frequency MOPA with 40 W output power and M2 < 1.2 consisting of an ultrastable 1 W non-planar ring cavity oscillator with outstanding single frequency characteristics and one Innoslab amplifier stage. The partially end pumped Nd:YVO4 Innoslab amplifier is set up in a folded single pass configuration. A 30 GHz tunable spectral bandwidth of 1kHz/100ms and a relative intensity noise (RIN) of < 1 10-5 Hz-1/2 (>10kHz) was measured in free-running mode. Together with an active intensity noise suppression electronics a RIN of < 5 10-7 Hz-1/2 (>10kHz) was achieved. A comprehensive discussion of experimental data is given.
