the lasers used at INRS produce ultrashort pulses in the femtosecond range (10-15 s) that are far too short to visualize. INRS professor and ultrafast imaging specialist Jinyang Liang and his colleagues, led by Caltech’s Lihong Wang, have developed what they call T-CUP: the world’s fastest camera, capable of capturing ten trillion (10-13) frames per second. This new camera literally makes it possible to freeze time to see phenomena — and even light! — in extremely slow motion.
Compressed ultrafast photography (CUP) gives 100 billion frames per second frames. but did not meet, the specifications required to integrate femtosecond lasers. To improve on the concept, the new T-CUP system was developed based on a femtosecond streak camera that also incorporates a data acquisition type used in applications such as tomography.
The first time it was used, the ultrafast camera broke new ground by capturing the temporal focusing of a single femtosecond laser pulse in real time. This process was recorded in 25 frames taken at an interval of 400 femtoseconds and detailed the light pulse’s shape, intensity, and angle of inclination.
