ABSTRACT:
A saturable reactor comprising a magnetic core (1) having an annular or an elongated race-track configuration, an electrical insulator (6) disposed around the magnetic core and a conductor winding (3) wound around the insulator (6). A coolant duct (7) is provided in the insulator to extend radially transversely across the magnetic core and having a radially separated inlet and outlet (8,9). A saturable reactor may comprises an annular magnetic core (51), a conductor winding including a first conductor (55) surrounded by the magnetic core (51) and a second conductor (56) disposed around the magnetic core and connected to the first conductor (55) through a load. A control winding (54) extends through the first and second conductors (55,56), and at least one of the first and second conductors (55,56) has a notch or a through hole (57,59) for insulatingly receiving the control winding (54) therein. Also disclosed is a laser oscillator comprising a gas-filled laser chamber (81) in which a main electrode pair (82,83) is disposed in an opposing relationship to define a laser-excited discharge region therebetween. At least some of the components of an oscillation circuit for generating a laser oscillation are disposed within a first circuit component chamber (95) disposed adjacent to the laser chamber (81) and filled with an electrically insulating gas, and some other components are disposed within a second circuit component chamber (96) disposed adjacent to the first circuit component chamber (95) and filled with an electrically insulating oil.
