Abstract
Intracavity frequency doubling of diode-pumped Nd:YVO4 lasers is expected to be a promising approach for an optical source of the future optical disk systems. In the previous paper, we have shown ultra high storage density erasable magneto-optical recordings of HDTV pictures played back by a stable compact green laser (CGL) consisting of Nd:YVO4 and KTP[1, 2]. The conversion efficiency of the CGL was up to 10% (50mW-diode laser to 5mW green output) due to large emission cross section and absorption coefficient of the Nd:YVO4 gain medium. In the CGL, single axial- and polarization-mode operation is important to avoid fluctuations in the green output power due to the nonlinear coupling between the modes[3,4]. To confirm a long term stability of the CGL, perturbations in cavity parameters for the single-mode operation must be considered.
