We have performed high resolution spectroscopy of rubidium with a single mode continuous wave distributed feedback (DFB) laser diode. The saturation spectrum of the D 2-line of 85 Rb and 87 Rb was recorded with a resolution close to the natural line width. The emission frequency was actively stabilized to Doppler-free transitions with a relative accuracy of(More)
2-Photon laser scanning microscopy (TPLSM) is often used for chronic in vivo studies. Small deviations in the sample orientation, however, make comparison of three-dimensional image stacks taken at different time-points challenging. When analysing changes of three-dimensional structures over time (4D imaging) this fundamental problem is one of the main(More)
