| Abstract: | Using the liquid glycerol as the target material,the characteristics of the laser plasma propulsion were investigated under different ambient temperature with ultra-short pulse laser ablation.The experimental results showed that the target momentum and ablation pressure were closely related to the ambient temperature.The reason was that the viscosity of glycerol was affected by temperature obviously. |

| Keywords: | laser plasma propulsion glycerol viscosity temperature |
