Abstract: A pulsed power circuit (30, 31, 32) including an inductor (55) having a hybrid core of a switch magnetic material arranged and selected to function as a magnetic switch a damping magnetic material arranged and selected to damp energy reflections without interfering with the switch magnetic material functioning as a magnetic switch so that the circuit can mitigate resonances caused by reflected energy without any significant degradation of its switching function as part of an saturable reactor inductor.

Abstract: One or more properties of an electrical quantity are determined based on one or more operating characteristics of an optical system that includes a laser system; an impedance of a magnetic core of a magnetic switching network is adjusted by providing the electrical quantity to a coil that is magnetically coupled to the magnetic core; and after adjusting the impedance of the magnetic core, a pulse of light is produced. Producing the pulse of light includes: saturating the magnetic core such that an electrical pulse is provided to an excitation mechanism of the laser system.

Abstract: Disclosed are methods of and apparatus for extending a useful lifetime of a laser discharge chamber in which a polarity of an electrode positioned at a fixed position within the chamber is caused to be positive with respect to the polarity of a second electrode defining a discharge gap with the first electrode and the first electrode is made of a material that forms an erosion resistant surface when the first electrode is used and an anode. Also disclosed is an arrangement in which a first electrode is positionable with respect a second electrode defining a discharge gap with the second electrode and the position of the first electrode controlled to maintain the width of the gap within a predetermined range.

Abstract: Systems, apparatuses, methods, and computer program products are provided for controlling a laser source that includes two laser discharge chambers. An example laser control system can include a first pulsed powertrain including a first independent circuit configured to generate a first resonant charging supply (RCS) output voltage. The first RCS output voltage can be configured to drive a first laser discharge chamber. The example laser control system can further include a second pulsed powertrain including a second independent circuit configured to generate a second RCS output voltage independent from the first RCS output voltage. The second RCS output voltage can be configured to drive a second laser discharge chamber independent from the first laser discharge chamber.
