An electrodeless laser-driven light source includes a laser that generates a CW sustaining light. A pump laser generates pump light. A Q-switched laser crystal receives the pump light generated by the pump laser and generates pulsed laser light at an output in response to the generated pump light. A first optical element projects the pulsed laser light along a first axis to a breakdown region in a gas-filled bulb comprising an ionizing gas. A second optical element projects the CW sustaining light along a second axis to a CW plasma region in the gas-filled bulb comprising the ionizing gas. A detector detects plasma light generated by a CW plasma and generates a detection signal at an output. 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.

Laser-driven light source with electrodeless ignition

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.

Inductively coupled plasma light source with switched power supply

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.

All-optical laser-driven light source with electrodeless ignition

A method of generating light with a laser-driven light source includes generating a CW sustaining light and propagating the CW sustaining light to a gas filled bulb comprising an ionizing gas. A pump light is generated. A Q-switched laser crystal is irradiated with the generated pump light, thereby generating pulsed laser light. The pulsed laser light is propagated to the gas filled bulb comprising the ionizing gas so as to generate a CW plasma that emits light. The light generated by the CW plasma in the gas filled bulb is detected. The pump light is controlled so as to extinguish the pulsed laser light after the light generated by the CW plasma is detected.

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.

An X-ray generation apparatus includes an electron gun configured to emit an electron beam, a rotary anode unit having a target generating an X-ray by receiving the electron beam and configured to rotate the target, a magnetic lens having a coil configured to generate a magnetic force acting on the electron beam between the electron gun and the target, and a wall portion disposed between the target and the coil so as to face the target. The wall portion is formed with an electron passage hole through which the electron beam passes and a flow path configured to allow a coolant to flow.

The target is positioned in a path of an output region of the source of laser radiation. The target includes an absorbing material that absorbs radiation at a wavelength within the lasing spectrum of the source of laser radiation and converts the absorbed radiation into thermal energy. The enclosure defines a cavity that includes the target. The enclosure includes an infrared reflecting film on a side that defines the cavity.

A method for producing light includes introducing an ionizable medium for generating a plasma into a chamber. The method also includes applying at least one pulse of energy to a magnetic core that surrounds a portion of a plasma discharge region within the chamber such that the magnetic core delivers power to the plasma which forms a secondary of a transformer according to Faraday's law of induction. The plasma has a localized high intensity zone.

Inductively-driven plasma light source

A system for delivering a desired mass of gas, including a chamber, a first valve controlling flow into the chamber, a second valve controlling flow out of the chamber, a pressure transducer connected to the chamber, an input device for providing a desired mass to be delivered, and a controller connected to the valves, the pressure transducer and the input device. The controller is programmed to receive the desired mass from the input device, close the second valve and open the first valve, receive chamber pressure measurements from the pressure transducer, and close the inlet valve when pressure within the chamber reaches a predetermined level. The controller is then programmed to wait a predetermined waiting period to allow the gas inside the chamber to approach a state of equilibrium, then open the outlet valve at time=t, and close the outlet valve at time=t* when the mass of gas discharged equals the desired mass.

Pulsed mass flow delivery system and method

Plasma ignition and cooling apparatus and methods for plasma systems are described. An apparatus can include a vessel and at least one ignition electrode adjacent to the vessel. A total length of a dimension of the at least one ignition electrode is greater than 10% of a length of the vessel's channel. The apparatus can include a dielectric toroidal vessel, a heat sink having multiple segments urged toward the vessel by a spring-loaded mechanism, and a thermal interface between the vessel and the heat sink. A method can include providing a gas having a flow rate and a pressure and directing a portion of the flow rate of the gas into a vessel channel. The gas is ignited in the channel while the remaining portion of the flow rate is directed away from the channel.
