26 Mar 2008 Novel concepts in spectral shear facilitate the development of this compact characterisation device. Based on a patented technology using a single crystal to up-convert two test pulses and to introduce spectral shear without the need of an additional chirped pulse, the LX SPIDER measures the spectral amplitude and phase using the SPIDER (Spectral Phase Interferometry for Direct Electric-field Reconstruction) algorithm. From the spectral quantities the temporal amplitude and phase are derived in real-time. The LX Spider is smaller than a shoe box, portable, easy to operate and characterises pulses down to 20fs duration. |
