Abstract

The results of designing, manufacturing and investigating characteristics of AlGaAs/InGaAs/GaAs lasers with ultranarrow waveguides are presented. Low threshold current density near 40 A/cm² has been observed for the lasers with quantum wells. We have demonstrated the possibility of obtaining up to 5 W of output power in continuous mode and up to 40 W in pulsed mode, with a beam convergence (FWHM) of 17.8° It is demonstrated that such lasers can exhibit main characteristics similar to conventional laser heterostructures and allow a potential for further improvement and optimization.
