     When a laser zaps an electron orbiting a proton, the electron undergoes what is called the Lamb shift, absorbing energy and jumping to a higher energy level. […] But instead of lasing electrons, Knowles examined protons with particles called muons, which he calls "the electron's fat cousin."

2. (intransitive) To operate as a laser, to release coherent light due to stimulation.

   Once enough of the gas particles are in a higher energy state, they will begin to lase and give off a coherent beam.
