Mode-locked lasers generate short pulses of intense coherent light. Just like a guitar string, laser cavities can support many different frequencies, or resonant modes. A train of picosecond or femtosecond pulses can be produced by actively or passively controlling the light in the cavity so that these different resonant modes interfere.
