We demonstrated an integrated system that can manipulate and measure vectorial field spanning up to the entire repetition period without ambiguity, iteration, and reference.
A compact iodine-stabilized laser at 531 nm is developed with a frequency stability at the 10−12 level using a coin-sized diode laser module. This laser will be used for applications including interferometric measurements.
Femtosecond lasers began to draw attention as a new light source for high-precision absolute distance measurements (ADMs) allowing for advanced principles such as synthetic wavelength generation, Fourier-transform-based dispersive analysis and multi-wavelength interferometry. In this talk, we present the state-of-the-art measurement principles and performance demonstrated by exploiting the unique...
The laser pulse width was measured on-site the mass spectrometer by scanning a dispersion in the pulse compressor. A pulse width of 49 fs measured was close to 35 fs calculated from the spectrum.
We isolate the vibrational free-induction decay of a homogeneous molecular subensemble using ultrafast infrared vibrational scattering-scanning near-field microscopy. The observed long-lived few picosecond vibrational coherences, intramolecular coherence transfer, and spatial variations in vibrational modes indicate non-ergodic behavior.
