Abstract:

We present an overview of the quantum design, growth and lasing operation of both IR and mid-IR OPSL structures aimed at extracting multi-Watt powers CW and multi-kW peak power pulsed. Issues related to power scaling are identified and discussed. The IR OPSLs based on InGaAs QW bottom emitters targeted at wavelengths between 1015nm and 1040nm are operated in CW mode yielding a maximum power of 64W and pulsed peak power of 245W. The mid-IR top emitter OPSLs designed to lase at 2 microns are based on a novel lattice mismatched growth using InGaSb QWs and yield a maximum peak power of 350W pulsed.
