To achieve room-temperature continuous-wave laser operation at visible wavelengths below 700 nm using modified AlGaAs double heterojunction structures.
Fabricated AlGaAs double heterojunction (DH) laser structures featuring a thick grown buffer layer.
Removed the substrate from the structure to facilitate continuous-wave operation.
Obtained continuous-wave threshold currents ranging from 60 to 120 mA within the 680–700 nm spectral band.
Achieved fundamental transverse and single longitudinal mode operation under continuous-wave excitation, with a shortest recorded wavelength of 683 nm.
