Suppression of the intensity noise of a laser-diode-pumped single-frequency ring Nd:YVO(4)-KTP green laser by optoelectronic feedback.
We investigate the different characteristics of the intensity noise of a laser-diode-pumped single-frequency ring Nd:YVO (4) laser and a Nd:YVO (4)-KTP green laser. By use of an optoelectronic feedback circuit connected directly to the pump current of the laser diode, the low-frequency intensity noise of the intracavity frequency doubler was suppressed to some extent.
