Abstract (en)
[origin: WO2021001185A1] In a pulse compressor (1) having a plurality of optical components (2-4), at least one of which is a diffraction grating (3), according to the invention at least one of the optical components (2-4) is fastened to the base plate (6) by means of at least three intermediate elements (5a-5c) which are laser-welded to one another, a first and a second intermediate element (5a, 5b) being fastened to the base plate (6) and a third intermediate element (5c) being fastened to the optical component (2-4). The joint surfaces (7b) of the first and the second intermediate element (5a, 5b) abutting the third intermediate element (5c) and the joint surface (8b) of the third intermediate element (5c) abutting the first and the second intermediate element (5a, 5b) are curved. At least the laser-welded joint surfaces of the at least one optical component (2-4), of the intermediate elements (5a-5c) and of the base plate (6) are formed from materials in which the difference between their coefficients of thermal expansion is less than 10e-6/K.
