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： The present invention provides long life optics for a modular, high repetition rate, ultraviolet gas discharge laser systems (Fig. 1B) producing a high repetition rate high power output beam (38). The invention includes solutions to a surface damage problem discovered by Applicants on CaF2 optics (4260) (422)(424)(426) located in high pulse intensity sections (10)(26) of the output beam (14C) of prototype laser systems. Embodiments include an enclosed (4) and purged beam path (14C) with beam pointing control (40A) (40B)(6) for beam delivery of billions of output laser pulses (38). Optical components and modules described herein are capable of controlling ultraviolet laser output pulses (14A) with wavelength less than 200nm with average output pulse intensities greater than 1.75x10 Watts/cm and with peak intensity or greater 3.5x10 Watts/cm for many billions of pulses (14A) as compared to prior art components and modules which failed after only a few minutes in these pulse intensities.

摘要： The present invention provides a control system for a modular high repetition rate two discharge chamber ultraviolet. In preferred embodiments, the laser is a production line machine with a master oscillator (10) producing a very narrow band seed beam which is amplified (12) in the second discharge chamber. Novel control features specially adapted for a two-chamber gas discharge laser system include (1) pulse energy controls, with nanosecond timing precision (2) precision pulse to pulse wavelength controls with high speed and extreme speed wavelength tuning (3) fast response gas temperature control and (4) F2 injection controls with novel learning algorithm.
