A Scanning Cavity Microscope
Matthias Mader, Jakob Reichel, Theodor W. Hänsch +1
Imaging of the optical properties of individual nanosystems beyond fluorescence can provide a wealth of information. However, the minute signals for absorption and dispersion are c…
Test of Time Dilation Using Stored Li+ Ions as Clocks at Relativistic Speed
Benjamin Botermann, Dennis Bing, Christopher Geppert +14
We present the concluding result from an Ives-Stilwell-type time dilation experiment using 7Li+ ions confined at a velocity of beta = v/c = 0.338 in the storage ring ESR at Darmsta…
An octave spanning mid-infrared frequency comb generated in a silicon nanophotonic wire waveguide
Bart Kuyken, Takuro Ideguchi, Simon Holzner +9
We demonstrate an octave-spanning frequency comb with a spectrum covering wavelengths from 1,540 nm up to 3,200 nm. The supercontinuum is generated by pumping a 1-cm long dispersio…
Few-cycle, Broadband, Mid-infrared Optical Parametric Oscillator Pumped by a 20-fs Ti:sapphire Laser
Suddapalli Chaitanya Kumar, Adolfo Esteban-Martin, Takuro Ideguchi +5
We report a few-cycle, broadband, singly-resonant optical parametric oscillator (OPO) for the mid-infrared based on MgO-doped periodically-poled LiNbO3 (MgO:PPLN), synchronously pu…
Differential femtosecond coherent Stokes and anti-Stokes Raman spectroscopy
Takuro Ideguchi, Simon Holzner, Ming Yan +3
We demonstrate a novel technique of coherent Raman spectroscopy with a femtosecond laser. We apply to a molecular sample a sequence of pairs of ultrashort excitation and probe puls…
