　　The plasma propulsion generated in nanosecond pulse laser interaction with polyimide film is investigated.A comparison of coupling coefficient and specific impulse with glass layer and water layer confinement is given.It shows that polyimide has a higher efficiency in water confinement ablation.Through doped carbon black in polyimide film, a higher coupling coefficient is obtained.In ablated surface images, less redeposited products has been observed.
