Using modulator-generated optical frequency combs we measure the distance to scattering technical surfaces. We achieve measurement errors below 10 μm, a dynamic range of over 37 dB and an acquisition time of 8.3 μs.
We demonstrate the use of pulse-front tilt in cross-correlation frequency-resolved optical gating (XFROG) to measure complex many-picosecond-long pulses on a single shot.
A method to characterize the linewidth enhancement factor or α-parameter of erbium doped fiber from measurements of the sensitivity to backreflection of DFB fiber lasers with a range of known resonator strengths is presented.
We present a new technique of non-linear dual-comb spectroscopy for the measurement of coherent Stokes and anti-Stokes Raman spectra of fundamental vibrational transitions. Ultrarapid acquisition times, high-resolution, broad-spectral-span are the main characteristics of our experiments.
