Laser Optical Loop for highly repetitive laser measurements by a single laser pulse — •Nikita Lepikhin, Dirk Luggenhölscher, and Uwe Czarnetzki — Institute for Plasma and Atomic Physics, Ruhr University Bochum, D-44780 Bochum, Germany

A Laser Optical Loop (LOL) approach is proposed to achieve high repetition rates of laser pulses by using each single laser shot several times. As a result, measurement speed of laser based experimental techniques can be accelerated significantly, e.g. Electric Field Induced Second Harmonic generation (E-FISH), Two-Photon Absorption Laser Induced Fluorescence (TALIF), Thomson scattering, etc. Several optical schemes are proposed to form the optical loop and to trap the laser emission. The feasibility of the suggested method is demonstrated using the example of the E-FISH technique.
