Abstract

This work presents a versatile pulsed single-mode Titanium:Sapphire laser system. It delivers ns-pulses with pulse energies of more than 24 mJ at a repetition rate of 250 Hz, corresponding to an average output power of over 6 W. The laser operates at wavelengths near 818 nm and is injection-seeded alternately with two diode lasers. This provides various wavelength-tuning possibilities and a frequency stability < 10 MHz with a linewidth < 100 MHz. The laser system acts as transmitter for a Differential Absorption Lidar (DIAL). The DIAL of the University of Hohenheim is a mobile ground-based scanning system that measures water vapor in the troposphere [1].
