摘要

研究了高功率脉冲辐射放大器中有源元件和白光元件的折射率nD和平均色散(nF - nC)对激光器和光学玻璃非线性折射率的影响。结果表明,所研究的玻璃在光谱的绿(黄)区折射率低于1.550,平均色散小于0.00820时,其非线性折射率不会超过允许的最大值1.20 × 10-13 cm2/B2。研究发现,所研究的玻璃的非线性折射率与折射率和平均色散几乎成线性关系。提出了非线性折射率低于限定值的非热磷酸盐冠可以作为获得低非线性折射率钕玻璃的基础。

The Dependence of the Nonlinear Refractive Index of Laser and Optical Glasses on Their Optical Constants

The Dependence of the Nonlinear Refractive Index of Laser and Optical Glasses on Their Optical Constants

The effect of the refractive index nD and mean dispersion (nF – nC) on the nonlinear refractive index of laser and optical glasses for active elements and elements of white optics of high-power pulsed radiation amplifiers is studied. It is shown that the nonlinear refractive index of the studied glasses will not exceed the maximum allowable value of 1.20 × 10–13 cm2/B2 if their refractive index in the green (yellow) region of the spectrum is below 1.550, and the average dispersion is less than 0.00820. It is found that the nonlinear refractive index of the studied glasses depends almost linearly on both the refractive index and the average dispersion. It is proposed that athermal phosphate crowns with a nonlinear refractive index below the specified limiting value can serve as the base for obtaining neodymium glasses with a low nonlinear index.
