<p>The inventive type form is provided with a transparent base for a preselected laser wave length. One of the surfaces thereof is embodied in the form of a solid solution of a base material, for example, glass, quartz, leucosapphire and of a material emitting acoustic impulses following the action of laser radiation impulses, for example, a metal and oxides or alloys thereof. In order to reduce the size of rejected drops, the base surface situated under the solid solution is covered with hollows, whereby the adjacent edges thereof contact each other.</p> |
