Experimenting on semiconductors using ablative laser propulsion to investigate propulsion parameters

A laser can be used to propel distant objects. The ability of silicon produce thrust and its propulsive parameters are needed studied in ablative propulsion (ALP). In this work, pure doped with indium were subjected ALP achieve the momentum coupling coefficient specific impulse investigate worth as a propellant. experiment was conducted using Nd:YAG (Quantel Brilliant) operating at fundamental harmonic (λ = 1064 nm 5 ns pulse duration). given range fluence, 1 × 105–5 105 J/m2, no significant difference among both samples for values (Cm) (Isp) is observed; instance, propellants follow decreasing trend Cm. However, maximum enhancement Cm Isp observed cavity aspect ratio one. enhanced about 1.75 4.5 times, respectively, silicon. external does not have any impact on indium-doped while showed considerable enhancement.
