Abstract :
The occurrence of kinks in the light-output/current characteristic of d.h.-laser diodes can be avoided by stabilising the lasing path. This is done by slightly misorienting the stripe contact with respect to the normal at the mirrors, or by changing the shape of the stripe contact. By this procedure the beam waist position with respect to the mirror is also stabilised.
