ENHANCED DIFFRACTION-LIMITED OUTPUT POWER OF TAPERED GAIN SEMICONDUCTOR-LASERS

The spatiotemporal dynamics of linearly and trumpet flared high bright ness semiconductor lasers are compared and contrasted using a comprehe nsive model built up from the microscopic physics. While both devices display complex multi longitudinal mode dynamics, the trumpet flared d evice is less susceptible to transverse filamentation instabilities an d, hence, displays superior time-averaged far-field imaging properties .
