Abstract: An electrodeless laser-driven light source includes a laser source that generates CW sustaining light. A pump laser generates pump light. A Q-switched laser crystal is positioned to receive the pump light and generates pulsed laser light in response to the generated pump light that propagates to a breakdown region in a gas filled bulb comprising an ionizing gas. A detector detects plasma light generated by a CW plasma located at least partly in a CW plasma region in the gas filled bulb comprising the ionizing gas and generates a detection signal. A controller generates control signals that control the pump light to the Q-switched laser crystal so as to extinguish the pulsed laser light within a time delay after the detection signal exceeds a threshold level.

Abstract: A rotary anode unit includes a target formed of a first metal material and a target support body formed of a second metal material, formed in a flat plate shape, and having first and second surfaces. A thermal conductivity of the second metal material is higher than a thermal conductivity of the first metal material. A first recessed portion is formed in the first surface at the outer part of the target support body. The target is disposed in the first recessed portion. A second recessed portion configured to define a flow path for allowing a coolant to flow is formed in the second surface at the inner part of the target support body. A thickness of a first region where the first recessed portion is formed is larger than a thickness of a second region where the second recessed portion is formed.

Abstract: An apparatus for producing light includes a chamber and an ignition source that ionizes a gas within the chamber. The apparatus also includes at least one laser that provides energy to the ionized gas within the chamber to produce a high brightness light. The laser can provide a substantially continuous amount of energy to the ionized gas to generate a substantially continuous high brightness light.

Abstract: An electrodeless laser-driven light source includes a laser source that generates a CW sustaining light and a pump laser that generates a pump. An optical beam combiner combines the CW sustaining light and the pump such that the CW sustaining light and the pump propagate co-linearly. A Q-switched laser crystal generates pulsed light in response to the pump. A gas-filled bulb is configured such that the pulsed light ignites a pulse plasma in a breakdown region of the gas bulb and the sustaining light sustains a CW plasma in a CW plasma region of the gas bulb, thereby emitting a high brightness light from the gas bulb, where the gas-filled bulb is positioned between the output of the pump laser and the pump input of the Q-switched laser crystal such that the CW plasma absorbs the pump light quenching the pulsed light generated by the Q-switched laser crystal.

Abstract: A method and apparatus for generating light includes a chamber having a high voltage region, a low voltage region, and a plasma generation region that defines a plasma confinement region. A magnetic core is positioned around the chamber and is configured to generate a plasma in the plasma confinement region. A switched power supply includes a DC power supply and a switched resonant charging circuit that together generate a plurality of voltage pulses at the output causing a plurality of current pulses to be applied to the power delivery section around the magnetic core so that at least one plasma loop is established around the magnetic core that confines plasma in the plasma confinement region, thereby forming a magnetically confined Z-pinch plasma. Light generated by the Z-pinch plasma propagates out of a port in the light source.

Abstract: A light emitting sealed body includes: a housing which stores a discharge gas and is provided with a first opening to which first light is incident along a first optical axis and a second opening from which second light is emitted along a second optical axis; a first window portion which hermetically seals the first opening; a second window portion which hermetically seals the second opening; and a first electrode and a second electrode. The housing is formed of a light shielding material which does not transmit the first light and the second light. An internal space is defined by the housing, the first window portion, and the second window portion and the internal space is filled with the discharge gas. The first opening and the second opening are disposed so that the first optical axis and the second optical axis intersect each other.
