Chirped mirror compressor
WebFeb 4, 2013 · A prism pair and a chirped mirror pair were used to compensate material dispersion compressing the pulse duration as short as 5 fs to be used for pump-probe measurement. The pulse duration can be compressed more as short as 3.9 fs inserting an additional chirp compressor made of a diffraction grating and a deformable mirror.
