Abstract

Laser ablation of carbon-doped glycerol at laser wavelengths of 1064 and 532 nm are characterized in laser plasma propulsion. The coupling coefficient, specific impulse and the plasma luminescence are measured. It is found that the coupling coefficient and the specific impulse are much related to the wavelength and the carbon content. A long wavelength and a high carbon content can enhance the coupling coefficient and specific impulse due to the prolonging coupling time of laser pulse with plasma. However, an optimal propulsion also relates with the un-ionized splashing liquids.
