Abstract

We investigate the different characteristics of the intensity noise of a laser-diode-pumped single-frequency ring $\mathrm{Nd}:{\mathrm{YVO}}_4$ laser and a $\mathrm{Nd}:{\mathrm{YVO}}_4–\mathrm{KTP}$ 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.
