Selective Laser Sintering (SLS) and Selective Laser Melting (SLM) are parent Additive Manufacturing processes using a laser to solidify metallic, ceramic, polymer or composite powders. During the process, the object is built layer by layer. A laser source ...
A distributed sensor system employing spontaneous Raman scattering with use of correlation-coding techniques and a single-detector scheme is discussed and experimentally characterised. A sensing distance of up to 8 km is achieved with high spatial and temp ...
Ceramic lasers have advantages such as better optical homogeneity, cheaper production, and more freedom in shape compared with monocrystalline lasers. However, equal or better laser performances are required. Interface segregation is important as ceramics ...
The aim of this project is to study the use of pulsed infrared laser light to stimulate the central auditory system. This novel approach may be a means to improve the efficacy of the current generation of electrically based Auditory Brainstem Implants (ABI ...
The alignment stability is a major concern for Thomson scattering systems. Even small angular deviations of the laser beams crossing the plasma lead to a loss of the calibration resulting in unreliable measurements of the electron density profile. For the ...
An approach combining microstructural and optical modeling based on atomistic simulation results is proposed, in order to assess the performance of Nd:YAG laser ceramics resulting rom luminescence and transparency changes as a function of grain size and do ...
Purpose: To demonstrate the feasibility of scleral wound closure using a novel adhesive made of chitosan film. Methods: Five-millimeter scleral lacerations were created in enucleated pig eyes. Casted chitosan films were sized to 7×7 mm patches. Lacerations ...

The authors demonstrate a sample method to achieve local tuning of optical modes in GaAs photonic crystal nanocavities by continuous wave laser-assisted oxidation in air atmosphere. By irradiation with a focused laser beam at power levels of a few tells of ...
In a test of principle a neutron spin filter has been built, which is based on dynamic nuclear polarization (DNP) using photo-excited triplet states. This DNP method has advantages over classical concepts as the requirements for cryogenic equipment and mag ...
