摘要: ABSTRACT To evaluate the thrust produced by photon pressure emitted from a 100 W class continuous-wave semiconductor laser, torsion-balance precise stand is designed and tested. Photon emission propulsion using light sources attract interests as possible candidate for deep-space propellant-less attitude control system. However, large several ten nanonewtons requires stand. A resonant method adopted to enhance sensitivity of biflier torsional-spring The torsional spring constant 1.245 × 10 -3 Nm/rad 0.118 Hz, respectively. experimental results showed good agreement with theoreti cal estimation. efficiency was also defined. maximum 499 nN laser 208 input power (75 optical output) corresponding 36.7%. minimum detectable estimated be 2.62 under oscillation at frequency close resonance.
