Definitions

  • a diode laser (the most common and inexpensive laser) essentially consists of a semiconductor sandwiched between two mirrors (one of which typically has a transmission coefficient of around 5%). These mirrors form a cavity in which light is reflected back and forth.
  • the mirror that is already part of the laser can be used as the coupling means to couple laser light into the fibre.
  • the laser cavity can be an external cavity.

Abstract

L'invention porte sur une lampe à laser comprenant un laser (10) couplé à une âme de guide de lumière (14) par l'intermédiaire d'un trou d'épingle (26). Le guide de lumière (12) est gainé avec une couche d'émission et/ou de diffusion de lumière (16). Dans un autre mode de réalisation, la lumière du laser (10) est couplée dans le guide de lumière (12) par l'intermédiaire d'un miroir semi-transparent (50). Un rendement lumineux élevé est obtenu pendant un refaçonnage de faisceau et la granularité est rendue minimale.
