Abstract: The dependences of the angular position and angular width of peaks in the far-field zone of a leaky-mode laser on the pump current are studied. It is found that an increase in the concentration of carriers in active layers results in a deviation of a laser beam with respect to the normal to the diode-laser facet and in a decrease in the beam divergence, while an increase in the temperature of waveguide layers compared to a substrate reduces the angle between the beam axis and the normal to the laser mirror.
