Measurement of large optical elements used for inertial confinement fusion with ptychography

Measurement of large optical elements used for inertial confinement fusion with ptychography AbstractHigh-power laser drivers are located in huge laser facilities built for inertial confinement fusion, and have achieved important progresses in the past decade; however, many unconventional optical elements implemented still cannot be accurately measured. To solve this problem, the ptychographic iterative engine (PIE), which is a recently developed technique that can detect both the phase and modulus of the light field simultaneously, is adopted to measure the transmission function of these optical elements and then to accurately characterize their key parameters. The distinctive advantage of PIE over other traditional metrology techniques in measuring large optical elements is demonstrated in this paper by detecting the focal length of a lens array and the surface profile of a continuous phase plate. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Advanced Optical Technologies de Gruyter

Abstract

AbstractHigh-power laser drivers are located in huge laser facilities built for inertial confinement fusion, and have achieved important progresses in the past decade; however, many unconventional optical elements implemented still cannot be accurately measured. To solve this problem, the ptychographic iterative engine (PIE), which is a recently developed technique that can detect both the phase and modulus of the light field simultaneously, is adopted to measure the transmission function of these optical elements and then to accurately characterize their key parameters. The distinctive advantage of PIE over other traditional metrology techniques in measuring large optical elements is demonstrated in this paper by detecting the focal length of a lens array and the surface profile of a continuous phase plate.
