| 摘 要： | 掺铜KNSBN(钾钠铌酸锶钡)光折变晶体具有光致吸收(LIA)特性.实验表明,泵浦光的光强越强,波长越短,LIA系数就越大,探测光为e偏振态时的LIA系数是o光时的1.2倍.这种现象将被用来提高光场的空间或时间均匀性. |
| 关 键 词： | 掺铜KNSBN晶体 光致吸收 光强均匀性 |

| Abstract: | Copper-doped KNSBN photorefractive crystal has the property of light-induced absorption(LIA).It is demonstrated experimentally that the coefficient of LIA is larger with more intense pump beam and shorter wavelength.When the probe beam is in state of ‘e’polarization the coefficient of LIA is 1.2 time larger when the pump beam is in state of ‘o’ polarization.The property can be applied to improve the homogeneity of the light field. |
| Keywords: | Copper-doped KNSBN crystal Light-induced absorption Light field homogeneity |
