Abstract

Very-low-noise operation (as low as −140 dB/Hz) of close-coupled Nd:YVO₄ lasers is reported. This low noise level has been attained by controlling the spectra of the pumping laser diodes into the single longitudinal mode by suppressing mode hopping. The small-packaged second-harmonic laser (ϕ12 × 16 mm) showed highly stabilized 530 nm/6 mW operations with a relative intensity noise of −140 dB/Hz.
