For a two-level system we developed quantum protocols in order to reach a final state in the shortest allowed time, with very high fidelity and robustness against imperfections in the experimental apparatus. [ABSTRACT FROM PUBLISHER]

Dependence of ethylene double ionization on laser pulse duration and intensity was studied by Coulomb explosion imaging technique. It was found that multiple molecular orbitals are involved in the strong field double ionization of ethylene. [ABSTRACT FROM PUBLISHER]

A laser-based thin-film processing scheme for printing and annealing of graphene oxide is reported. This method is able to print and simultaneously reduce the graphene oxide to graphene. The resulting graphene thin film is with good transmittance and its resistance is dramatically reduced from 200 MΩ to 80 KΩ. [ABSTRACT FROM PUBLISHER]

Lasing at both 589.0 nm and 589.6 nm in Na has been realized by photoassociating Na-rare gas pairs. [ABSTRACT FROM PUBLISHER]

Laser induced unidirectional molecular rotation is shown to give rise to macroscopic flow and rotational vortices which last orders of magnitude longer than the collision time or the laser pulse duration. [ABSTRACT FROM PUBLISHER]

Size control of laser synthesized gold nanoparticles in different solvents is reported. Our two-step green-synthesis approach employs only the fundamental harmonic of a Nd:YAG laser at kHz repetition rates for sub-10 nm nanoparticles production. [ABSTRACT FROM PUBLISHER]

We demonstrate a novel mass spectrometry nanoprobe that uses soft x-ray laser ablation to map chemical composition. Composition maps of metal/dielectric/polymer samples with 250nm surface and 50nm depth resolution were obtained. [ABSTRACT FROM PUBLISHER]

A shaped femtosecond laser can selectively excite a coherence in a particular Raman mode. This concept is used to produce chemical images of an explosive simulant in a polymer background in a standoff configuration. [ABSTRACT FROM PUBLISHER]

Laser-diode pumped Yb3+-doped LuAG ceramic laser is reported. Maximum 2.14 W output power and 72% slope efficiency were obtained. Higher thermal conductivity and higher emission cross-section than Yb:YAG will be suitable for thin-disk laser. [ABSTRACT FROM PUBLISHER]

Picosecond lasers for bulk machining of transparent dielectrics are assessed as an alternative to fs-lasers. Nanogratings and micro-channels by selective etching are demonstrated. Scattering and inhomogeneous etching are challenges yet to be solved. [ABSTRACT FROM PUBLISHER]

We present recent advances, combining novel laser technologies and spectroscopic methods, for high-sensitivity detection of volatile organic compounds within the context of the formation of secondary pollutants that affect human health and climate. [ABSTRACT FROM PUBLISHER]
