在文中探讨了在曲面条件下的激光直写焦深改进的措施。 - The results of computer simulation show that both the radius of disk and the depth of focal length decrease as increasing incidence wavelength , meanwhile , the intensity of disk is enhanced
数值计算了圆形透镜的色散，结果表明：焦斑的半径和焦深随入射波长的变大而减小，光斑的强度随入射波长的变大而增强。 - If a nd : yag laser runs at high pump power , laser resonator will generate multimode beam due to thermal lens of active rod . the higher pump power is , the bigger divergence occurs and the smaller rayleigh range is
当nd ： yag激光器工作在高泵浦功率下时，由于nd ： yag激光器工作物质的热透镜效应导致了谐振腔输出多模激光，随着泵浦功率的升高激光光束发散角增大，焦深减小。 - The results show that radius and position of focal beam waist , focal angle and focal depth describe focal beam properties . they are determined by waist and rayleigh length of beam before focusing , the position and focal length of focus mirror
聚焦光束束腰位置和半径、聚焦角、焦深、焦点偏移量以及焦点漂移量是描述光束聚焦特性的主要参数,它们由四个参量共同决定,分别为聚焦前光束的束腰半径、瑞利长度和聚焦镜的焦距以及聚焦镜到光束束腰位置的距离。
