Abstract

L'invention concerne les dispositifs de production d'un rayonnement cohérent intense dont le nombre d'onde est environ de 628 cm** -1. La cavité 10 contient de la vapeur qui présente au moins trois niveaux d'énergie, le premier et le deuxième étant séparés par un quantum d'énergie correspondant à un nombre d onde d'environ 628 cm **1, la transition entre eux étant favorisée par rapport à toutes les autres transitions possibles à partir du premier niveau. Les moyens de pompage 15 peuvent pomper les atomes du troisième au premier niveau. Le réglage precis est assuré par les moyens de réglage 20. Applicable à la réalisation de lasers réglables autour de la valeur indiquée.The invention relates to devices for producing intense coherent radiation having a wave number of approximately 628 cm ** -1. The cavity 10 contains vapor which has at least three energy levels, the first and the second being separated by a quantum of energy corresponding to a wave number of about 628 cm ** 1, the transition between them being favored over all other possible transitions from the first level. The pumping means 15 can pump the atoms from the third to the first level. The precise adjustment is ensured by the adjustment means 20. Applicable to the production of lasers adjustable around the indicated value.
