Abstract
Quantum cascade lasers (QCL’s) have proven their usefulness as light sources in many applications, like remote gas sensing, molecular spectroscopy or free-space communication. In most cases the high-quality low-divergence beam is desired. This work presents the theoretical analysis of QCL’s beam divergence. The electromagnetic field in the resonator is calculated according to effective index method. Theoretical results are compared with measurements.
