DESIGN OF A 1 W, SINGLE FILAMENT LASER-DIODE

A design of a high power laser structure is presented which is based o n an increase of the cavity length as well as a maximization of the st ripe width. This requires a low value for the modal attenuation coeffi cient and a low optical confinement factor. A model is presented from which the modal gain, the confinement factor, the active region thickn ess, the stripe width, the length and the reflection coefficients can be calculated. A variant for all design parameters needed to reach 1 W emission in the fundamental lateral mode is given. These values are u sed to design the epitaxial structure.
