Abstract

The analysis of novel vertical external-cavity surface-emitting laser (VECSEL) designed for simultaneous dual-wavelength emission is presented. Inhomogeneous optical pumping of the nonidentical quantum wells of the active region has been studied. The novel rate equations description of our VECSEL is presented taking into account a strong time-delayed feedback. Steady-state stability conditions and the dynamics of dual-wavelength lasing have been investigated. It appears that tendency to self-pulsation due to Q-switching at high pump power is avoidable by accurate modeling and epitaxial growth of the active region of the laser
