Until now, a complex experimental setup was required to measure the shape of a laser lightwave with a high degree of accuracy. This measurement can now be done using a small crystal with a diameter of less than 1 mm. The new method, developed by scientists at the Max Planck Institute (MPI) for Quantum Optics, Ludwig Maximilian University (LMU), and the Vienna University of Technology (TU Wien), uses extremely short pulses, with a duration in the order of femtoseconds.
“In order to create an image of such lightwaves, they must be made to interact with electrons,” professor Joachim Burgdörfer said. “The reaction of the electrons to the electric field of the laser gives us very precise information about the shape…READ MORE
