A laser diode has a gain peak between 4.45-4.65 µm, and we want to have only a single mode at 4.5 µm as output of this laser diode. What should be the length of the laser so that only a single mode is allowed within the laser? Take the refractive index within the active region as 3.2. (This type of laser is called short cavity laser).
