Low-noise diode-pumped intracavity-doubled laser with off-axially cut Nd:YVO(4).
Effective noise reduction in a diode-pumped intracavity-doubled Nd:YVO(4) laser is achieved with a novel cavity design in which a birefringent filter is formed with off-axially cut Nd:YVO(4) and KTP. 20-mW green output with relative intensity noise of less than -120 dB/Hz was obtained under 290-mW pumping by a broad-area laser diode.
