发明名称 METHOD OF FEEDBACK CONTROL OF ELECTRON BEAM LASERS
摘要 <p>In a method for producing a laser beam issuing from a gaseous working medium in a working region, it is known for the gas to be subjected to an electric field and for an ionizing beam to be directed to the gas, ionizing the gas and producing therein secondary electrons sufficient to support laser action. In this invention, the power of the laser beam is controlled by controlling the power of the electron beam and the electron beam power is controlled by an electrical feedback signal from a radiation detector that detects a fraction of the laser beam reflected from a plurality of reflective small wires carried by a rotatable hub which causes the wires to sequentially pass through the laser beam and reflect a small fraction of the laser beam towards the radiation detector.</p>
