Study on Sensitivities of Ghost Images to Lens Fabrication Errors in High Power Laser Facilities
As the further discussion on the ghost images in high-power laser facilities, the sensitivities of the ghost images focal positions to lens fabrication errors are analyzed based on the traditional studies. The general expression of ghost images focal length is deduced approximately, and the relation between shifts of ghost images focal position and errors of lens parameters are calculated based on the matrix optics. The numerical calculation results by taking the focal lens of the final optical assembly in SG-Ⅱ upgraded system as example indicate that the ghost images are sensitive to the lens central errors, but insensitive to the errors of curvature radius and center thickness. It can offer the reference in optical designs.
