“…During laser plasma propulsion, the laser irradiation of a target surface yields strong plasma ejection and a thrust force is induced in the opposite direction. In this case, the properties of the propellant (metals, polymers and liquids) have a remarkable effect on the thrust performance [7][8][9][10][11][12][13]. Liquid propellants have high thrust and high coupling coefficient and are therefore considered very promising materials.…”

“…For example, the correlation between the viscosity of a liquid and the propulsion efficiency has been determined [14,15]. Moreover, the carbon powder (the diameter between 100 and 130 nm) has been proposed as a doping material to increase the liquid viscosity so as to reduce the splashing [12,16]. Considering both the high doping and the high absorption ability of carbon, carbon-doped glycerol has recently been proposed [12].…”

The ablation characteristics of carbon-doped glycerol were investigated in laser plasma propulsion using a pulse laser with 10 ns pulse width and 1064 nm wavelength. The results showed that with the incident laser intensity increasing, the target momentum decreased. Results still indicated that the strong plasma shielded the consumption loss and resulted in a low coupling coefficient. Furthermore, the carbon-doping gave rise to variations in the laser focal position and laser intensity, which in turn reduced the glycerol splashing. Based on the glycerol viscosity and the carbon doping, a high specific impulse is anticipated.
