Further, LISA has built
a prototype of a 2 µm laser system for wake vortex detection
based on the Doppler principle. This Q-switched laser system operates
at a single frequency in the fundamental transversal mode delivering
pulse energies up to 10 mJ.
LISA has successfully participated in various research programs
on cw and pulsed 2 µm laser systems. Some were granted by
the German ministry of research. The development of a demonstrator
for wake vortex detection has been supported by the EC in the frame
of the IWAKE project within FP5. At the time LISA is engaged in
the VERTIGO project within FP6.
