    摘要： A laser device includes a seed laser, an amplifier, a detector, and an optical element arranged to direct radiation emitted by the seed laser towards a plasma generation site. The optical element is arranged to direct towards the detector amplified spontaneous emission radiation which has been emitted by the seed laser and has been reflected from a droplet of fuel material. The detector is arranged to trigger generation of a laser radiation pulse by the seed laser when the reflected amplified spontaneous emission radiation is detected.

    摘要： An EUV radiation generation apparatus includes a laser configured to generate pulses of laser radiation, and an optical isolation apparatus that includes a rotatably mounted reflector and a radially positioned reflector. The rotatably mounted reflector and the laser are synchronized such that a reflective surface of the rotatably mounted reflector is in optical communication with the radially positioned reflector when the optical isolation apparatus receives a pulse of laser radiation to allow the pulse of laser radiation to pass to a plasma formation location and cause a radiation emitting plasma to be generated via vaporization of a droplet of fuel material. The rotatably mounted reflector and the laser are further synchronized such that the reflective surface of the rotatably mounted reflector is at least partially optically isolated from the radially positioned reflector when the optical isolation apparatus receives radiation reflected from the plasma formation location.

    摘要： A lithographic apparatus includes an illuminator for receiving a beam of EUV radiation from a radiation source apparatus and for conditioning the beam to illuminate a target area of a patterning device, such as a reticle. The reticle forms a patterned radiation beam. A projection system transfers the pattern from said patterning device to a substrate by EUV lithography. Sensors are provided for detecting a residual asymmetry in the conditioned beam as the beam approaches the reticle, particularly in a non-scanning direction. A feedback control signal is generated to adjust a parameter of said radiation source in response to detected asymmetry. The feedback is based on a ratio of intensities measured by two sensors at opposite ends of an illumination slit, and adjusts the timing of laser pulses generating an EUV-emitting plasma.
