Shapes of laser-produced alkali-hydride crystalline particles (laser snow) are observed for the first time. Particles are suspended by an electric field so as to grow large enough to be observed by an optical microscope. It is found that the particles are single crystals and have particular shapes depending on the gas temperature and the laser-light intensity.
