Abstract
Des constructions de cellule de gaz unique fondées sur une fibre de cristal photonique à noyau creux sont utilisées, par exemple, dans une cavité de laser à anneau de fibre comme cellule de gaz intracavité. Selon un mode de réalisation, deux blocs de jonction simples sont couplés à des extrémités opposées de la fibre de cristal photonique à noyau creux. Chaque bloc présente un trou débouchant principal ayant une fenêtre optique à une extrémité et un mandrin de fibre optique ajusté à lautre extrémité, un trou transversal croisant le trou principal et présentant un raccord de gaz pour le branchement à une source de gaz ou à une pompe à vide. Selon un autre mode de réalisation, la fibre de cristal photonique à noyau creux est contenue dans une enceinte, dont les parois sont dotées de fenêtres optiques et dorifice à gaz. Dans lenceinte, des pinces à fibre soutiennent les extrémités de la fibre de cristal photonique à noyaux creux à des positions adjacentes à un alignement sur les fenêtres optiques.
