At the Vienna University of Technology (TU Vienna) a new world record has now been set; using a special merging technique, two symmetrical laser structures have been joined together, resulting in a quadruple intensity of laser light.
These applications may bring back memories of the legendary “Tricorder” from Star Trek, a portable multi-purpose analytical instrument. For measuring objects at a distance and for medical imaging, compact light sources with a very high optical power are required.
