Energy scaling of passively Q-switched lasers In the Mj-range
Author(s): J. Neumann; R. Huss; C. Kolleck; Dietmar Kracht

Paper Abstract

Q-switched lasers systems with ns pulse duration and energies ranging from 1 to more than 100mJ are utilized for many spaceborne applications such as altimetry of planets and moons. Furthermore, Q-switched lasers can be used for distance measurements during docking and landing manoeuvres. To keep the diameter of the beam small over a large distance and to consequently achieve a good lateral resolution, a good beam propagation factor M² is required. Moreover, Q-switched lasers can be used directly on the planetary surface for exploration by laser-induced breakdown spectroscopy or laser desorption mass spectrometry.
