In a laser diode element including a front facet, a rear facet, a laser cavity formed between the front and rear facets and which has a predetermined length L and an active layer and a uniforming grating having regular corrugation formed in the direction of the laser cavity and which are coupled to each other at a predetermined coupling constant K. The partial grating divides the laser cavity into a short length side and a long length side and is interposed between the short length side and the long length side.
L'invention est une diode laser ayant une facette avant, une facette arrière, une cavité laser de longueur prédéterminée L formée entre les facettes avant et arrière, ainsi qu'une couche active et un réseau d'uniformisation à ondulations régulières formés dans la direction de la cavité laser et couplés l'un à l'autre avec une constante de couplage prédéterminée K. Le réseau partiel divise la cavité laser entre un côté court et un côté long et est monté entre le côté court et le côté long.
