“…A Bell nozzle thruster (Bohn and Schall, 2002;Perri and Weiss, 1972;Tang, Gong and Hu, 2003) in which a parabolic mirror is used to concentrate the incident laser beam and to reflect induced blast waves achieved a high C m of up to 400 N MW −1 with a laser pulse energy of about 200 J using a TEA-CO 2 laser. Figure 2 portrays the data of measured C m for various vehicle geometries.…”

“Beamed Energy Propulsion” is distinguished by its use of a collimated laser or microwave beam that enables long‐distance wireless power supply, no‐fuel airbreathing flight, high heating rates (detonation and ablation) by beam focusing, and other useful features. Remotely powered space propulsion is a potential alternative to chemical and electric propulsion. Compact onboard laser thrusters also provide unique features. This chapter presents a worldwide review of beamed energy propulsion studies, most of which have been reported at the series of International Symposium on Beamed Energy Propulsion (ISBEP).

“…As a result, laser propulsion is more favored in numerous aerospace engineering aspects of launching objects into low Earth orbit, attitude control or orbit adjustment of satellites, and space debris removal [7][8][9][10][11]. In general, laser propulsion can be divided into air-breathing mode [12] and ablation mode [13] according to various propellants. For the former, air itself acts as the propellant without carrying any working medium whereas it is not effective enough to propel the objects beyond an altitude of 30 km [7].…”

In this study, the influence of laser energy and pressure on propulsion performance of zinc and acrylonitrile butadiene styrene (ABS) is investigated by impulse measurement, fast exposure images, spectral diagnostics and target ablation. A Q-switched Nd: YAG laser with the wavelength of 1064nm and pulse width of 6 ns is employed. The impulse and coupling coefficient generated by laser ablation ABS are greater than that of Zn, and they exhibit a similar variation trend with pressure. However, at higher pressure levels, the change in impulse versus laser energy is not completely coincident between Zn and ABS samples. The target property plays a significant role in the generation and propagation of plume related to the plasma parameters such as electron density and temperature. The temporal evolution images indicate that the plasma plume of laser-induced Zn presents a faster decay in comparison with that of ABS, which is ascribed to the fact that the gas temperature of ABS is higher than the electron temperature of Zn plasma in the local thermodynamical equilibrium. Also, the electron density is lower for Zn due to the rapid heat diffusion and higher ablation threshold of metal. It is found that the surface absorption is dominant for metal because the ablated crater of Zn performs larger diameter and shallower depth. On the contrary, the shrinkage in diameter but enhancement in depth of crater is observed from ABS surface, and the ablation mass is larger, suggesting the obvious volume absorption for polymer. The results reveal that the target property can engender an important effect on the energy conversion between laser, target and plasma.
