    摘要: A laser light source is disclosed having a laser oscillator producing an output beam; a first amplifier amplifying the output beam to produce a first amplified beam, and a second amplifier amplifying the first amplified beam to produce a second amplified beam. For the source, the first amplifier may have a gain medium characterized by a saturation energy (Es, 1) and a small signal gain (go, 1); and the second amplifier may have a gain medium characterized by a saturation energy (Es, 2) and a small signal gain (go, 2), with (go, 1)>(go, 2) and (Es, 2)>(Es, 1). In another aspect, a laser oscillator of a laser light source may be a cavity dumped laser oscillator, e.g. a mode-locked laser oscillator, q-switched laser oscillator and may further comprising a temporal pulse stretcher.

    摘要: A method for producing extreme ultraviolet light includes producing a target material at a target location; supplying pump energy to a gain medium of at least one optical amplifier that has an amplification band to produce an amplified light beam; propagating the amplified light beam through the gain medium using one or more optical components of a set of optical components; delivering the amplified light beam to the target location using one or more optical components of the optical component set; producing with a guide laser a guide laser beam that has a wavelength outside of the amplification band of the gain medium and inside the wavelength range of the optical components; and directing the guide laser beam through the optical component set to thereby align one or more optical components of the optical component set.
