摘要： There is disclosed continuously-excited lasers of the CO.sub.2 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.sub.2 which is initially transferred to a storage chamber provided between a rotatable storage cylinder (16) and an axial supporting shaft (18) therefor, and thereafter the N.sub.2 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.sub.2 and He, entering through supply tubes (23), and to which it transfers its excitation before flowing to the resonator.

摘要： A two-wavelength I.R. pyrometer for monitoring the rapid heating of materials by C W lasers or electron beams. The I.R. radiated from the material is separated into two closely adjacent wavelengths and signal values representative of those wavelengths are obtained. These signal values are then processed through an electronic circuit where the signal value of one of the signals is held substantially constant by a feedback control while the other signal value is influenced by approximately the same feedback control applied to the first signal value and wherein the resultant signal values are then processed through a circuit determining a ratio of one signal value divided by the other. This is then a measure of the temperature of the material. Also disclosed is a chopper wheel for a two-wavelength I.R. pyrometer. The wheel has a plurality of circumferentially extending I.R. filters of alternating wavelengths (.lambda..sub.1, .lambda..sub.2).
