Perturbation de l'iode moléculaire en phase vapeur par la présence de gaz étrangers. Conséquence pour la stabilisation du laser He-Ne

2014 A very sensitive method to test the presence of gaseous impurities in molecular iodine cells is presented and applied. The results prove the great importance of these impurities. It is shown that the presence of these gases can limit the reproducibility of the He-Ne laser stabilized on iodine. A technique to fill very clean cells is described and the quality of such cells is discussed. REVUE DE PHYSIQUE APPLIQUÉE TOME 12, MAI 1977, PAGE Classification Physics Abstracts 5.446 5.448 0.460
