The FR-103PD Autocorrelator utilizes Two Photon Conductivity (TPC) in photodetectors*. TheNL crystal/PMT combination of conventional autocorrelators (FR-103XL, FR-103MN) is replaced by a photosensor in the TPC mode, acting as both the NL element and detector. The stringent phasematching condition of the NL crystal being eliminated, polarization sensitivity and wavelength dependence are greatly reduced, resulting in a simple operation with easy alignment.
DISPERSION-FREE, HIGH RESOLUTION
Using only metallic high-reflective optics [the sole transmissive element is an ultrathin (~1µm)pellicle beamsplitter] dispersion-free operation with high resolution is attained. Resolution is limited by the generally broad wavelength response of the photosensors.
ROTATING PARALLEL MIRROR ASSEMBLY
FEMTOCHROME's rotating //mirror assembly** is utilized to generate periodic linear delay, with a scan range of > 50ps, convenient for pulse width
in the fs to < 10ps domain. [For longer pulses, FR-103XL (> 175ps scan range) is recommended.]
