Abstract :
A new semiconductor injection laser (Quantum Cascade Laser) which differs in a fundamental way from diode lasers has been demonstrated. It relies on only one type of carrier (it is a unipolar semiconductor laser), and on electronic transitions between conduction band energy levels of quantum wells
