Optimizing the Energy Efficiency of Debris Removal from a Laser Propulsion Perspective

Abstract

The energy efficiency of accelerating debris is particularly important in laser debris removal techniques. A calculation model depends on the laser focusing intensity, wavelength, and pulse width to evaluate the efficiency which is maximized when the ablation switches from evaporation to plasma generation. Based on this consideration, laser pulse energy can be evaluated based on the shape and mass of the debris to be removed.
