| 摘 要： | 在调Q 纳秒Nd: YAG强激光脉冲下,使用闭孔Z-扫描技术研究了硼硅酸盐基质玻璃及其掺Nd3+玻璃的三阶光学非线性特性.发现基质玻璃具有正的三阶非线性折射系数和非线性吸收系数,属于自聚焦反饱和吸收型的光学介质;而随着Nd3+的掺入,该硼硅酸盐玻璃的三阶非线性折射和吸收系数较基质玻璃有明显的增大,远高于一个量级.用开孔Z-扫描实验与光限幅实验进一步验证了掺Nd3+玻璃具有较高的三阶非线性吸收系数,表明Nd3+的掺入提高了硼硅酸盐玻璃在532 nm处的激光防护性能. |
| 关 键 词： | Z-扫描 掺Nd3 玻璃 三阶光学非线性 光限幅 激光防护 |

| Abstract: | The third-order optical nonlinearities of the borosilicate glass and two types of Nd3+-doped glass are measured by the closed-aperture Z-scan technique using Qnanosecond Nd:YAG third-order laser pulses.It is found that the matrix glass possesses a positive nonlinear refractive index and a positive nonlinear absorption coefficient,belonging to self-focus antisaturation optical medium.Both the third-order nonlinear refractive index and absorption coefficient of Nd3+-doped glasses are one order larger than tho... |
