  • Since materials such as gallium nitride or zinc selenide used for configuring lasers that emit a laser beam with a wavelength less than 450 nm have numerous lattice defects, and because of auto-compensation effects, the confinement of current and light within the active layer is weakened and spontaneously emitted light tends to be emitted from spots other than the emission point.
