FROG stands for Frequency-resolved Optical Gating. It is a technique for a complete characterization of ultrashort pulses, thus it can retrieve the full time-dependant electric field, and the equivalent optical spectrum with spectral phase. In other words, FROG allow you to know the duration of your pulses, but also how to deal with spectral phase to reach the shortest possible duration.

The Fast FROG is a single-shot FROG, thus it needs one single pulse to measure the duration. Its innovative algorithm allow a real-time pulse retrieval.

Based on Second Harmonic Generation, Fast FROG is reliable and compact. Key design features, such as the wavefront division technique and the use of our mini imaging spectrometer MISS, make the Fast FROG very easy to use and versatile while leading to accurate measurements. Six models are available, covering different pulse duration ranges from sub-5 fs to 10 ps, over a broad spectral range. Two designs are available: one for long pulses mainly relying on transmission optics, and one for ultrashort pulses which is fully achromatic.
