High-power narrow-stripe semiconductor lasers (1060 nm) at ultrahigh pump levels

A comparative analysis of two types of heterostructures (1) symmetric with a single-mode ultrathin waveguide (0.1 μm thick) and (2) asymmetric with a multimode ultra-wide waveguide (1.7 μm thick). In the case of heterostructure (2) the maximum CW optical power reached is 1.6 W at 25 degrees and 2 W...

Description
Summary:A comparative analysis of two types of heterostructures (1) symmetric with a single-mode ultrathin waveguide (0.1 μm thick) and (2) asymmetric with a multimode ultra-wide waveguide (1.7 μm thick). In the case of heterostructure (2) the maximum CW optical power reached is 1.6 W at 25 degrees and 2 W at -8 degrees, while the maximum efficiency reached is 54 %. Under the pulsed pump for both types of heterostructures, there is a time domain of unstable lasing.
