I came across this term while reading texts on Quantum Optics and Lasers. While I know something about multimode laser oscillations, I am unsure about what is exactly meant by multimode light?

  • $\begingroup$ Multi-mode implies many different frequencies. Two-mode means two frequencies and so on. $\endgroup$ – suresh Oct 15 '14 at 6:46
  • $\begingroup$ @suresh How does a laser exhibit multimode effects then? Isn't a laser supposed to emit at a particular frequency? $\endgroup$ – AKSHIT KUMAR Oct 15 '14 at 6:50
