Tub4.4 - LASER LEVEL SELECTION IN TERAHERTZ QUANTUM CASCADE LASERS

Abstract

Abstract

The active region of a terahertz quantum cascade laser with two optical transitions is studied. The population of upper laser states, which correspond to 3.4 and 3.8 THz, are investigated at different operating temperatures and in a strong magnetic field.
