摘要:We report on a novel pseudothermal light source based on laser light coupled into an optical multimode fiber. The setup is simple, low cost, exhibits inherently high directional light emission and allows for a flexible arrangement. By measuring the photon statistics and spatial t...

摘要:We present a new cavity ring-down spectroscopy system which was developed for variable-temperature absorption measurements (220–290 K) of atmospheric gases. This laser spectrometer was developed in the framework of the NASA Orbiting Carbon Observatory-2 project to improve ou...

摘要:We report on a modified nonlinear optical measurement technique using an absorptive phase object (PO) to characterize weak optical refraction nonlinearities. The absorptive PO consists of a circular silica substrate on which a dielectric plate has been deposited. The inner d...

摘要:We constructed a matter-wave beam splitter on an atom chip using a 87Rb Bose–Einstein condensate. Using radio-frequency-induced double-well potentials, we were able to coherently split a BEC into two clouds separated by distances ranging from 2.8 to 57 μm. Interfe...

摘要:We have developed a low-power, open-path, near-infrared (NIR) tunable diode laser sensor for the measurement of near ground-level concentrations of greenhouse gases. Here, we report on instrument design, characterization, and initial measurements of carbon dioxide concentrat...

摘要:A high-power sub-60 fs mode-locked diode-pumped Yb:KGW laser based on hybrid action of an InGaAs quantum-dot saturable absorber mirror and Kerr-lens mode locking was demonstrated. The laser delivered 56 fs pulses with 1.95 W of average power corresponding to 450 kW of peak power....

摘要:Cw oscillation of molecular iodine on many lines in the range of 557–802 nm pumped with a low power common diode pumped and frequency doubled solid state laser DPSSL is reported. The DPSSL is temperature stabilized, operates in single frequency and can be tuned by about 2 nm...

摘要:In this paper, we propose an approach to enhance the electron energy gain in standard laser-driven plasma wakefield accelerators, using accelerating Bessel pulses with tunable group velocity so to avoid electron dephasing. We use in the numerical simulations a one-dimensiona...

摘要:A cascaded multi-dithering (CMD) technique using piezoelectric ceramic transducer (PZT) tubes as phase modulators is proposed as a tool for obtaining high control bandwidth in coherent laser beam combination. To prove its validity, eight coherent fiber beam elements were com...

摘要:We present a numerical analysis that focuses, for the first time to our knowledge, on the feedback-induced dynamics in a semiconductor passively mode-locked laser with sub-wavelength resolution. Our results and the corresponding theoretical explanations elucidate several aspects ...
