Abstract: Continuously - excited lasers of the CO u mixing, and supersonic CO, types. There is specifically disclosed a method, and a laser apparatus, for producing a repetitively pulsed output, in which a stream of excited gas, of the type having a relatively long excitation life, is produced, stored and subsequently transferred, in the form of pulses, to a power extraction zone incorporating a resonator. In one example the gas laser is a supersonic CO laser in which the CO is excited in the excitation zone and is, after storage, transferred under supersonic conditions to the resonator. In the main example the gas to be excited is N u which is initially transferred to a storage chamber provided between a rotatable storage cylinder (16) and an axial supporting shaft (18) therefore, and thereafter the N u is transferred through holes (17) in the storage cylinder (16) which align during rotation with slots (20) through a surrounding fixed cylinder (19) to allow pulses of excited gas to be transferred to the power extraction zone (12) where it is mixed with CO u and He, entering through supply tubes (23), and to which it transfers its excitation before flowing to the resonator.

Abstract: Pyrometre a infrarouge permettant de controler le chauffage rapide de materiaux a l'aide de lasers CW ou de faisceaux d'electrons. Les rayons infrarouges irradies par le materiau sont separes en deux longueurs d'ondes tres proches et l'on obtient des signaux representant les deux longueurs d'ondes. Ces signaux sont ensuite traites dans un circuit electronique, la valeur de l'un des signaux etant maintenue sensiblement constante par regulation alors que la valeur de l'autre signal est influencee par sensiblement la meme regulation que celle qui est appliquee au premier signal, les valeurs de signaux resultantes etant ensuite traitees par des moyens produisant un rapport d'une des valeurs divisee par l'autre valeur. Ceci constitue donc une mesure de la temperature du materiau. Une roue de partition pour un spectrometre a infrarouge est egalement decrite. La roue (3) comporte une pluralite de filtres a infrarouge s'etendant dans le sens de la circonference, de longueurs d'ondes alternees (1, 2).
