Plate and λ/2 plate were placed inside the Nd∶YVO4KTP green laser cavity with angle 90°between their fast axis.The composite plate composed of HWP,QWP and KTP has the function of QWP.The composite plate with Nd∶YVO4 can effectively suppress the coupling of polarized modes,and multi-longitudinal-mode lownoise green laser was obtained.Since the composite plate counteracted the phase shift induced by temperature sensitivity of quartz plate,the green laser operated with lownoise reliability in different output power and different operation temperature.The threelongitudinalmode, the noise of less than 0.5% and output power stability of less then 1% for 12 hour are obtained in the green laser.

We put it across that the sign of nonlinear refractiveindex changes under certain conditions if the high-order excited state contributessignificantly to the refractive index.The nonlinearity changes from self-defocusing to self-focusing if the refrangibility of the ground state is larger thanthat of the first excited state and smaller than that of the second excited state.

高阶激发态折射度贡献较大时，非线性折射率符号在一定条件下存在转化：如果基态折射度大于低阶激发态的折射度而小于高阶激发态折射度，材料发生自散焦—自聚焦转化；如果基态折射度小于低阶激发态折射度大于高解阶激发态折射度则发生自聚焦—自散焦转化。
