Abstract

To improve the alignment precision of laser beam and target for high power laser driving device in Inertia Confinement Fusion(ICF)

several kinds of laser beam aligning methods

such as inside chamber direct alignment method

outside chamber direct alignment method

and indirect alignment method with Laser and Target Alignment Sensor(LTAS) based on optical conjugate principle

were induced and their advantages and disadvantages were analyzed. Then

the precision of the last method including the image measuring error

the errors introduced by protective glass of CCD

the movement errors of guides and the calibration error of Laser and Target Alignment Sensor(LTAS) was discussed. The experiments and precision analysis indicated that the laser beam aligning precision induced by LTAS is 10 m

which shows proposed LTAS can rapidly and exactly align the laser and target of large-scale laser driving device.
