Abstract

Tube laser 2 thermiquement compensé disposé entre des miroirs d'extrémités 3 et 4 avec d'un côté du tube une plaque quart-d'onde 6 et de l'autre côté un prisme polarisant 8 pour réfléchir la lumière hors de la cavité suivant un second axe vers un troisième miroir 9, une paire de modulateurs Q 7 et 10 étant disposés l'un sur l'axe laser il et l'autre sur l'autre axe 12 de maniere à corriger l'effet de birefringence thermique.Thermally compensated laser tube 2 disposed between end mirrors 3 and 4 with on one side of the tube a quarter-wave plate 6 and on the other side a polarizing prism 8 to reflect the light out of the cavity along a second axis to a third mirror 9, a pair of Q modulators 7 and 10 being arranged one on the laser axis 11 and the other on the other axis 12 so as to correct the thermal birefringence effect.
