1. A vacuum chamber, comprising:
a source material that has been pressed onto a substrate to reduce surface area and to attach the source material to the substrate, wherein the source material emits an atom vapor when heated to perform an atomic experiment or an atomic application within the vacuum chamber; and
a window disposed on a surface of the vacuum chamber so that a laser can pass through the surface to heat the source material, wherein the substrate is transparent such that the laser first passes through the substrate before reaching the source material.
