Many variations and modifications may be made to the above-described embodiment s of the invention without departing substantially from the spirit and principles of the invention. All such modifications and variations are intended to be included herein within the scope of this disclosure and the present invention and protected by the following claims. A laser-operated light source encompasses a chamber for accommodating an ionizable gas and an ignition source for ionizing the gas in the chamber for generating a plasma.

We claim: 1. A laser-operated light source, comprising: a chamber for accommodating an ionizable gas and a plasma formed by energizing the ionizable gas, the chamber further comprising an output window selected from the group consisting of a flat output window and a spherical output window;. The light source according to claim 1 , wherein the optical system further comprises collimating optics and focusing optics arranged downstream from the collimating optics.

The light source according to claim 1 , further comprising an ignition source for ionizing the gas in the chamber for generating the plasma. The light source according to claim 1 , wherein the optical system is corrected for more than two wavelengths of the useful light.
