With the development of laser propulsion, laser photon propulsion has become the focus of propulsion technology for deep space exploration. At present, laser photon propulsion is mainly based on continuous laser with long-distance transmission irradiation. Short pulsed laser has the advantage of high peak power. Therefore, the nanosecond high-repetition-frequency pulse laser for photon propulsion technology is proposed in this paper. In this paper,the impulse characteristics of photon propulsion with high-repetition-frequency nanosecond pulsed laser are studied by using the torsion pendulum. In the experiment, the laser wavelength, the pulsed width, and the repetition frequency is 1064 nm, 160 ns, and 10 kHz, respectively. The reflectivity of the output coupling mirror is 90%. The corresponding laser power range in the cavity is from 144 W to 414 W in the experiment. The local sliding fitting method is used to realize the smooth and noise reduction of the original data. The experimental results show that the impulse increases linearly with the increase of the output laser power. The impulse and the average thrust during the pulse time are calculated,respectively. The research results of this paper provide technical reference for the development of laser photon propulsion in space propulsion.
