Light amplification by stimulated emission of radiation - LASER Energy levels - Specific levels in an atom or molecule where electrons can occupy and jump between. Photon - A particle of light emitted when an electron drops to a lower energy level in an atom. Monochromatic - Having only one wavelength of light. Coherent - Oscillating in the same phase, with all photons moving together. Collimated - A narrow, parallel beam of light that can be directed precisely.
