Abstract

Ablative laser propulsion earned a potential significance for its ability to propel any distant object. It can be used in defense and security applications, such as disabling unauthorized drones or neutralizing explosives from a distance. It also has applications to micro- and nano-satellites for micro-orbiting and attitude control along with debris removal. To investigate the propulsive parameters of barium ferrite (BaFe12O19) by ablative laser propulsion, the material was subjected to Nd:YAG laser at 1064 nm wavelength and 5 ns pulse duration at laboratory conditions. BaFe12O19 was synthesized using chemical methods and subjected to different sonication time to check its effectiveness as propellants. The specific impulse and coupling coefficient were calculated at laser fluence 1e5–5e5J/m2. A maximum of specific impulse (ISP) 2500 s along with enhanced coupling coefficient (Cm) in the range of 3.1119e−4 to 3.2190e−4 N s/J has been achieved. The achieved results showed that it can be used as promising material in the manufacturing of laser thrusters to amplify the propulsion applications.
