A 167-m fiber-based optical frequency comb interferometer was stabilized to nm-level with extremely wide scanning of 2.8 m by frequency scanning. Fiber noise cancellation with direct use of a frequency comb was also demonstrated.
We demonstrated an integrated system that can manipulate and measure vectorial field spanning up to the entire repetition period without ambiguity, iteration, and reference.
Quantum state reconstruction techniques are used to address non equilibrium matter states. Proof of principle experiments reveal that few photons coherent pulses can be squeezed by the interaction with impulsively excited coherent phonons in quartz.
We discuss novel approaches towards observation of dynamical localization, a phenomenon believed to occur in the periodically δ-kicked quantum linear rotor and is related to one-dimensional Anderson localization.
We report the measurement of the resonance fluorescence spectrum from a quantum dot under periodically-pulsed excitation. The evolution of multiple sidebands and Rabi oscillations for coherently and incoherently scattered light were observed.
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.
The fs-laser induced refractive index change in zinc aluminum phosphate glasses and its underneath structural modifications have been investigated both at the surface and in bulk.
Optical limiting effects can be enhanced by designing nonlinear optical materials and by exploiting various limiting mechanisms. Here, we present the enhancement of optical limiting effects by manipulating the polarization distribution of the light field.
