A fundamental test of running a very small wooden ship model with laser propulsion was performed. The pulsed Nd·YAG laser beam (λ=532nm) through a lens placed on a ship was focused to cause a laser-gas breakdown above it. The blast wave of hot air involving a shock wave and gas expansion by a plasma was used for propellant. Experimental results of the thrust and the efficiency of laser energy converted to propulsion force were F=4.0 [dyn] and η=7.4×10^-5[%], respectively.
