摘要： A high resolution etalon-grating spectrometer or monochromator. A preferred embodiment presents as extremely narrow slit function in the ultraviolet range and is very useful for measuring bandwidth of narrow band excimer lasers used for integrated circuit lithography. Light from the laser is focused into a diffuser (D) and the diffused light exiting the diffuser illuminates an etalon (ET). A portion of its light exiting the etalon is collected and directed into a slit positioned at a fringe pattern of the etalon. Light passing through the slit is collimated (L3) and the collimated light illuminates a grating (GR1) positioned in an approximately Littrow configuration which disperses the light according to wavelength. A portion of the dispersed light representing the wavelength corresponding to the selected etalon fringe is passed through a second slit (2) and monitored by a light detector (PMT). When the etalon and the grating are tuned to the same precise wavelength a slit function is defined which is extremely narrow as about 0.034pm "FWHM" and about 0.091pm "95 percent integral". The etalon and the grating are placed in a leak-tight containment (50) filled with a gas, such a nitrogen or helium.

摘要： A line narrowing apparatus and method for a narrow band DUV high power high repetition rate gas discharge laser producing output laser light pulse beam pulses in bursts of pulses is disclosed, which may comprise a dispersive center wavelength selection optic contained within a line narrowing module, selecting at least one center wavelength for each pulse determined at least in part by the angle of incidence of the laser light pulse beam containing the respective pulse on a dispersive wavelength selection optic dispersive surface; a first dispersive optic bending mechanism operatively connected to the dispersive center wavelength selection optic and operative to change the curvature of the dispersive surface in a first manner; and, a second dispersive optic bending mechanism operatively connected to the dispersive center wavelength selection optic and operative to change the curvature of the dispersive surface in a second manner. The first manner may modify a first measure of bandwidth and the second manner may modify a second measure of bandwidth such that the ratio of the first measure to the second measure substantially changes. The first measure may be a spectrum width at a selected percentage of the spectrum peak value (FWX%M) and the second measure may be width within which some selected percentage of the spectral intensity is contained (EX%). The first dispersive optic bending mechanism may change the curvature of the dispersive surface in a first dimension and the second in a second dimension generally orthogonal to the first dimension. The laser system may comprise a beam path insert comprising a material having an different index of refraction and an index of refraction thermal gradient opposite from that of a neighboring optical element. The first dispersive optic bending mechanism may change the curvature of the dispersive surface in a first dimension and the second a second dimension generally parallel to the first dimension. An optical beam twisting element in the lasing cavity may optically twist the laser light pulse beam to present a twisted wavefront to the dispersive center wavelength selection optic. Bending may change the curvature and wavelength selection, e.g., in a burst may create two center wavelength peaks to select FWX%M and EX% independently.
