Electrons,lectron. The wavelength—momentum relationship that follows from the de Broglie’s hypothesis leads naturally to the Schr?dinger wave equation which carries important information concerning the energy and momentum of the electron.

Lasers,ccur if the stimulated emission rate exceeds the stimulated absorption rate. Such a situation cannot occur in a two level system because the same two levels are responsible both for absorption and emission of photons. In a three or four level system, the equilibrium between absorption and emission i

Quantum Cascade Lasers,nce band optical transition to generate the laser emission. As a result, the threshold power density in the interband cascade laser is lower by an order of magnitude compared to the quantum cascade laser.
