CA 2242853

A method of reducing the amount of unwanted radiation emitted from a semiconductor laser device involves coating a transparent portion the device intended to transmit radiation with a partially reflective layer. The transparent portion is typically the lens cap.

Méthode utilisée pour réduire la quantité de rayonnement non désiré émise par un dispositif à laser semi-conducteur. Elle consiste à revêtir une partie transparente du dispositif afin de transmettre le rayonnement à l'aide d'une couche partiellement réflectrice. La partie transparente est généralement le couvercle muni d'une lentille.
