A laser-diode-pumped Nd:YVO{sub 4} microchip laser was built and actively frequency stabilized relative to a Fabry{endash}Perot cavity with the frequency-modulated sideband technique. The error signal reaches the shot-noise level of 7.4 mHz/Hz around 1 kHz. Excess intensity noise sets a lower limit of 16.5 mHz/Hz for the relative frequency noise, corresponding to a spectral linewidth of 860 {mu}Hz. We discuss the method for reconstructing the actual frequency deviation from the observed error signal. {copyright} {ital 1996 Optical Society of America.}
