Abstract: Prior power supplies adapted to provide power to the lasers of multiple ring laser gyros were inefficient in that they were required to have power output capabilities far in excess of that required to sustain laser operations. Such inefficiency is greatly reduced by the present power supply comprising a DC power source (30) for producing a firing voltage at a first terminal (40) and a sustaining voltage at a second terminal (42), and interface means (50) associated with each laser (12, 13, 14) for coupling the laser to the first and second terminals. The firing voltage is capable of firing each laser, and the sustaining voltage is capable of sustaining current flow through each laser after firing. Each interface means comprises a resistor (52, 53, 54) connecting the laser to the first terminal and a diode (55, 56, 57) for connecting the laser to the second terminal such that the diode does not permit current flow between the first and second terminals.

Abstract: Les éléments d'alimentation antérieurs pour les lasers de gyroscopes à lasers annulaires multiples étaient inefficaces en ce sens qu'il devaient avoir une capacité de puissance de sortie très supérieure à celle qui était nécessaire pour entretenir le fonctionnement du laser. Cette inefficacité est réduite dans une large mesure par cet élément d'alimentation qui comprend une source (30) d'énergie à courant continu pour appliquer une tension d'allumage à un premier terminal (40) et une tension d'entretien à un deuxième terminal (42), et un dispositif d'interface (50) associé à chaque laser (12, 13, 14) pour coupler le laser au premier et au deuxième terminaux. La tension d'allumage peut allumer chaque laser, et la tension d'entretien peut entretenir l'écoulement du courant dans chaque laser, après leur allumage. Chaque dispositif d'interface comprend une résistance (52, 53, 54) qui connecte le laser au premier terminal et une diode (55, 56, 57) pour connecter de telle façon le laser au deuxième terminal que la diode ne permette pas au courant de s'écouler entre le premier et le deuxième terminaux.
