摘要： A transverse flow gas transport laser including a closed loop of ducting through which a gaseous lasing medium can be circulated so as to pass continuously through a lasing region of the ducting in which it can be excited into lasing activity, in which there is included means for extracting a portion of the gaseous lasing medium from a region of the ducting other than the lasing region, comprising the said portion of the lasing medium and injecting it back into the remainder of the lasing medium thereby to induce flow of the gaseous medium through the lasing region of the ducting.

摘要： A transverse flow gas discharge laser in which the cathode has an elongated cross-section the larger dimension of which is positioned at an angle to the direction of flow of the gaseous lasing medium. The anode of the laser is of modular construction and consists of an array of individually ballasted cylindrical buttons. Both the anode and the cathode are so positioned that they intereact aerodynamically with the adjacent duct wall to produce a stable electric discharge between them.
