Quantum-well ridge GaAs/AlGaAs heterostructure lasers are studied at high pump currents. It is shown that their catastrophic optical damage (COD) is preceded, as a rule, by a giant kink caused by the collapse of a waveguide in a horizontal plane. It

The waveguide design of a laser heterostructure is optimised to expand the laser beam in the vertical direction at the output mirror of a laser diode (up to 1.5 μm at the half intensity for the zero mode). Experimental samples of such diodes operate

More than 200 mW of a single-transverse-mode cw output power is produced from a semiconductor heterolaser by optimising the waveguide properties of its ridge structure. The laser-beam divergence is close to the diffraction limit and its brightness ex

An optical model is constructed for a GaAlAs/GaAs stripe-geometry laser heterostructure with a ridge-waveguide configuration in the p-type emitter layer. This waveguide configuration provides lateral optical confinement. The directional characteristi

The parameters of a 0.81-mu m ridge heterolaser are optimised by using the procedure developed earlier. As a result, 200 mW of the single-mode output is obtained in a diffraction-limited beam. It is shown experimentally that the near-field two-dimens

Tests were made on laboratory samples of cw GaAIAs/GaAs lasers. The service life was determined at room and elevated temperatures. Conversion to room temperature yielded the lognormal distribution of failure with an average operational lifetime of 3.

Continuous-wave losing was achieved at temperatures up to 70°C in mesastripe AlGaAs heterojunction lasers consisting of stripes 10-μ wide (emission wavelength 835-845 nm) attached on the substrate side to a copper heat sink. This made it possible t
