Miniature laser

From Memory Alpha, the free Star Trek reference

A miniature laser is a component of a microscope laser.

Doctor Leonard McCoy kept his miniature lasers with the lab shelf supplies aboard the USS Enterprise. After the crew became miniaturized, Christine Chapel offered to get the miniature laser for McCoy to use the microscope laser to repair Hikaru Sulu's broken leg. (TAS: "The Terratin Incident")
