optical technology is go back a long way in hanover hanover Laser Center
was founded in 1986 Over the past
20 years pioneering work has been carried out especially in the field space and laser technologies these are cornerstones of our work in quest in various that area the
inquests research area indeed enabling technologies we have concentrated the technology areas of quest that are there to stimulate and support science and the other areas these include technologies which are later used for storing Co atoms and molecules laser technologies which are used for future gravitational wave detectors or for optical clocks fiber technologies which play an important role in all areas and of course space technologies which are going to make it possible 1 day to conduct certain experiments in space so for
example in the group ultra high quality optical Mohism characterization new optical materials in thin film processes
for these components are being developed in
up there is a component of intersection laser components we're trying to optimize optimal coating processes and it to produce ultra high quality optical layers the Gospels and under the auspices of the Excellence Initiative we're trying to improve these well-established coating processes and to produce fewer losses at all and with this this diffusion and less absorption and the highest possible reflectivity of everyday
mirrors don't reflect enough not to be used
in lasers simple ladies and there is often used to be made of polished metal usually copper or on any and all that were made of glass and coated with gold or silver such mirrors have major disadvantages but part of the laser light penetrates the metal and is absorbed then edition and there is
not that any laser light through but our
aim is to reflect the laser beam with virtually
no loss and to use it outside the system for this we make multi-layered
and there's these consist of 2 transparent materials with different refractive
indices by stacking the different materials
we get a series of and
effect the interleaving produces a high
reflectance value such called died
electric multilayer yeah go at the left of if we took an everyday shaving their and introduce United they haven't put too much mirrors next to each other and kept reflecting the light back and forth would have after about 100 round well liked being would no longer be visible that's absolutely useless for laser we need a significantly higher reflectivity so that the beam can travel back and forth a million times between 2 mirrors and now we want to increase this before activity to a hundred million times because any with these high quality mirrors is it possible to run the modern optical clocks we want to use in quest I it's interesting someone the so outstanding there's are absolutely essential for building a
stable optical clock but these are the result 1 essential element in article clock other research areas within question responsible for other equally essential
components In area of the main area
d we working on the Subpart that's a laser with a very narrow line so it can measure atomic transitions with extremely high precision but this is of great relevance for optical clocks which will 1 day replace the atomic clocks we know today in order to bring even higher precision into the various experiments so it was the only the only the essential basis for this subpart Salazar is a resonator that is produced using special coating on construction technology and we're working on this resonator above all in 1 area the laser
technology is also becoming more and more widespread as oral laser opens up possibilities that we did Renault the past all in space or laser systems also have to be particular challenges that have considered
for instance what that's the vacuum has on the optical systems house gamma radiation
harms the system and much more interesting so the rest of us meticulously
you view of the um very inquest we're concerned with technologies that are new to send laser all the optical systems and space these technologies have to take not only the primary on the optical properties of such a system into account but above all the mechanical thermal properties here for
example we are developing a laser oscillators that have to be very small and compact or at the same time being able to cope with the rough environmental conditions of space the so they have to be
mechanically stable enough to stand behind vibrations shocks and was also the very
great ranges in temperature that can occur on or will we test such systems for example in thermal vacuum chambers wire chamber like the
1 you can see here in the background where we can put these systems into a vacuum and then test them at very wide temperature ranges as in this case from minus 72 plus 170 degrees of 1 of the but this time is about together with enough so the
European World Space Agency ESA is planning an expedition to Mars in 2018 the goal of the models room and this will contain technology from hunger was then the center that members of quest of help to develop so the
user will be used to look for traces of
organic material on
