Paper Abstract

This paper outlines the operation of a synchro scan streak camera in conjunction with a phase coupled Nd:YAG laser in order to perform range measurements to artificial satellites at two wavelengths simultaneously. The driving frequency for both, the laser optoacoustic modelocker and the streak camera, is obtained from a stable frequency standard. The synchronization of transmitter and receiver permits the designation of phases to the laser pulses detected by the streak camera relative to the transmitted ones. Therefore ranges can be determined in modulo parts of the driving frequency. In order to calibrate the device, ranging to a local ground target was carried out. It is shown that a standard deviation of about 10 ps can be reached operating the device in multi photon mode, despite the fact that the laser is operated with 200 ps FWHM pulses. The analysis of the satellite laser ranging experiments show that this high precision can be reached as well in the earth to space propagation channel.
