Abstract

A pulse compressor includes a plurality of optical components. The plurality of optical components includes a diffraction grating. A first optical component of the optical components is fastened to base plate by at least first and second intermediate elements that are laser-welded to one another. The first intermediate element is fastened to the base plate and the second intermediate element is fastened to the optical component. A joining surface of the first and second intermediate elements is formed as a bearing recess and another joining surface is curved. At least the laser-welded joining surfaces of the first optical component, the base plate, and the first and second intermediate elements are formed from materials for which a difference in their coefficients of thermal expansion is less than 10e-6/K.
