Boy you got me on that one. My impression was that a pulsed laser was preferable to CW for semi lithography. As to the lens design, I think they will still use calcium floride, since the refractive index is acceptable and it is almost transparent to the deep UV wavelengths.

I believe I read a release recently where Cymer has doubled the pulse rate and reduced the dose 50% to help alleviate the heating problem of the lens.

The boys at Hoya and OCLI could give you much better insight on this.
