Abstract

L'invention concerne un laser à réseau de Bragg réglé par compression comprenant un élément optique réglable (20, 600), lequel comporte soit une fibre optique (10) sur laquelle est imprimé au moins un réseau de Bragg (12) logé dans une partie au moins d'un tube capillaire de verre (20) et fusionné à celui-ci, soit un réseau de guides d'ondes de grand diamètre (600) doté d'un coeur et d'une large gaine. Une première lumière (14) est incidente sur le réseau (12), une seconde lumière (16) étant réfléchie à une longueur d'onde de réflexion μ1. L'élément réglable (20, 600) est soumis à une compression axiale, ce qui provoque un changement de longueur d'onde de réflexion du réseau (12) sans déformation dudit élément. La forme de cet élément peut présenter des géométries variables (forme de bobine, par exemple), et/ou plusieurs réseaux ou paires de réseaux peuvent être utilisés. De même, on peut utiliser plusieurs fibres (10) ou coeurs (612). Une partie au moins de l'élément peut être dopée entre une paire de réseaux (150, 152), d'où la formation d'un laser réglé par compression. Le réseau (12) ou les réseaux (150, 152) peuvent également être conçus sous la forme d'un laser à rétroaction distribuée réglable. Par ailleurs, ledit élément (20) peut comporter une zone intérieure diminuée (22) ou des sections (27) effilées (ou cannelées). La compression peut être réalisée au moyen d'un transducteur piézoélectrique (PZT), d'un moteur pas à pas, d'un dispositif hydraulique ou d'un autre dispositif d'actionnement.
