A·P·E offers a choice of solutions for ultrafast pulse measurements. Each is tailored to your type of laser system, with a wealth of innovations for greater accuracy and user simplicity.
From material processing to scientific and medical base research, ultrafast laser systems are used in many areas of their high peak intensity and extremely short pulse width. One relevant area of application is time resolved spectroscopy. The pulse width is a critical factor for the adjustment of these laser systems and the characterization of experiments. APE autocorrelators measure this parameter from 10 fs ... 400 ps for almost any wavelength range.
Compact and Tuning-free Autocorrelator
The Mini TPA by APE is the perfect combination of tuning-free autocorrelation measurement, compact size and high sensitivity.
Tuning-Free Wavelength Matching
Conventionally, autocorrelators used to split an optical pulse into two replicas and recombine them for the Second Harmonic Generation (SHG) in a nonlinear crystal. The APE Mini TPA instead benefits from the two photon absorption principle. This eliminates the need of SHG crystal angle tuning and makes the wavelength tuning process unnecessary.
UV Range without Cross-Correlation
Together with an UV Optics Set, the Mini TPA provides simple pulse width measurement in the UV range, from 340 nm to 400 nm — without the need for cross-correlation. Elimination of the cross-correlation approach also makes the data evaluation easier, by cutting the conventional two-step process to a single-step solution.
Ultra-wide Wavelength Coverage in Compact Design
APE provides a selection of exchangeable Optics Sets, ranging from UV at 340 nm to IR at 3200 nm, for sensitive measurements across an extremely broad wavelength region. Due to its compact footprint, the Mini TPA is also the perfect answer to your space-saving and easy portability requirements.
