Abstract

A “comb” structure of beam intensity distribution is designed and achieved to measure a target displacement of micrometer level in laser plasma propulsion. Base on the “comb” structure, the target displacement generated by nanosecond laser ablation solid target is measured and discussed. It is found that the “comb” structure is more suitable for a thin film target with a velocity lower than tens of millimeters per second. Combing with a light-electric monitor, the ‘comb’ structure can be used to measure a large range velocity.
