For all the beams, with the increase of laser duration, the impulse increased but Cm, Isp, and η decreased. The round beam has a higher Isp, and η under the same pulse duration due to the highest power intensity. Rectangular beam just has the highest impulse under the same laser energy density. Under a rectangular beam of 400 µm × 10 µm, GAP showed a better propulsion performance than DBP. GAP with a thickness of 50 µm exhibited a better performance than the GAP with a thickness of 30 µm. If a higher power density from a laser with a rectangular beam can be available by compressing the beam further or by improving the laser power, even higher propulsion performance can be expected.
