Unlike ordinary light, which contains many colors and spreads in all directions, laser light is mostly one color, with coherent waves that.. Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of.
