Abstract
Very-low-noise operation (as low as -140 dB/Hz) of close-coupled Nd:YV O4 lasers is reported. This low noise level has been attained by contr olling the spectra of the pumping laser diodes into the single longitu dinal mode by suppressing mode hopping. The small-packaged second-harm onic laser(phi 12 x 16 mm) showed highly stabilized 530 nm/6 mW operat ions with a relative intensity noise of -140 dB/Hz.
