A laser diode as a light source for calibrating the time base of a streak cameraFunded under: FP2-FUSION 10C
The DC operation of some laser diodes produces high frequency amplitude modulation of the laser output in the GHz frequency range. This phenomenon provides a simple and inexpensive method for checking the sweep linearity of a fast gated streak camera. The report gives details of the experiments performed on the JET tokamak, using a gated Thomson-CSF streak camera, and comments on the results obtained. It concludes that laser diodes provide a useful light source for calibrating sweep speed and quantum efficiency of streak cameras as well as for testing the sweep linearity.
