91321 Intensity auto-correlator - 2''/50mm Parabolic mirror based



The 3DOptix’s intensity auto-correlator is assembled from three modules: beam splitter module, delay line module and nonlinear SHG module. The incoming signal is splitted in a 99221 or 99021 beam splitter, then the two beams are delayed in our 99121 delay line module, which separate the beams into two parallel beam with 1.5''/37.5 mm interval. These beams are inserted into a 90712 nonlinear SHG module, which generate the second harmonic output exactly on the 3Doptix grid, allowing an easy and accurate alignment. Due the fact that all elements are exactly on the 3D grid, the three modules can easily be assembled together or can be separate on the optical table.
