    We demonstrate that (F2+^{+}_{2})AH_{\rm AH} centres of KCl may be obtained from crystals doped with K2_{2}CO3_{3} and NaCl, grown by the Czochralski method in open atmosphere. The optical properties of (F2+^{+}_{2})AH_{\rm AH} centres thus produced are exactly the same as those of (F2+^{+}_{2})AH_{\rm AH} centres prepared by the usual technique, which involves superoxide doping and a controlled atmosphere.Nous montrons que les centres (F2+^{+}_{2})AH_{\rm AH} de KCl peuvent ĂȘtre obtenus Ă  partir de cristaux dopĂ©s par K2_{2}CO3_{3} et NaCl, fabriquĂ©s par la mĂ©thode de Czochralski Ă  l'air libre. Les propriĂ©tĂ©s optiques des centres (F2+^{+}_{2})AH_{\rm AH} ainsi produits sont exactement les mĂȘmes que celles des centres (F2+^{+}_{2})AH_{\rm AH} prĂ©parĂ©s par la technique habituelle, qui comporte le dopage par un superoxyde et l'emploi d'une atmosphĂšre contrĂŽlĂ©e
