Low thermal conductance bi-material microcantilevers are fabricated with a pad area near the free end to accommodate a focused laser spot. A pair of such cantilevers are proposed as a configuration for measuring thermal conductance of a nanostructure suspended between the two. We determine the resol ... [Rev. Sci.

Laser scribing of functional thin-film stacks attracts increasing attention especially for applications of flexible electronics or photovoltaics. Laser can perform selective removal of the thin-film stacks that is essential for the isolation and interconnection of the solar cells. The optimization o ... [Rev. Sci.

A thermal property microscopy technique based on frequency domain thermoreflectance (FDTR) is presented. In FDTR, a periodically modulated laser locally heats a sample while a second probe beam monitors the surface reflectivity, which is related to the thermal properties of the sample with an analyt ...

This paper contains the design of the beam dump for the ITER edge Thomson scattering system and mainly concerns its lifetime under the harsh thermal and electromagnetic loads as well as tight space allocation. The lifetime was estimated from the multi-pulse laser-induced damage threshold. In order t ... [Rev. Sci. Instrum. 84, 103503 (2013)] published Tue Oct 8, 2013.

We demonstrate the use of random laser emission for mechanical testing of bovine pericardium. An apparatus designed for tensile tests of soft and thin materials, incorporating optical and mechanical devices, allows for obtaining the mechanical behavior of the tissue samples. Using both, digital imag ... [Rev. Sci. Instrum. 84, 104301 (2013)] published Fri Oct 4, 2013.

The interference signal visibility V (difference to sum ratio of intensities at maximum and minimum interference) of an interferometer that uses a multimode laser is here derived for a given laser gain profile and spectral mode separation as a function of the difference Z between the probe and refer ...

A novel approach for monochromatizing and focussing the Vacuum-Ultraviolet and soft x-ray radiation from high-order harmonic generation of a femtosecond optical laser with only one optical element is presented. We demonstrate that off-axis reflection zone plates applied as focussing monochromators a ... [Rev. Sci. Instrum. 84, 103102 (2013)] published Fri Oct 4, 2013.

Laser Thomson scattering (LTS) is an established plasma diagnostic technique that has seen recent application to low density plasmas. It is difficult to perform LTS measurements when the scattered signal is weak as a result of low electron number density, poor optical access to the plasma, or both. ... [Rev. Sci.

We have developed an atom trap trace analysis (ATTA) system to measure Kr in Xe at the part per trillion (ppt) level, a prerequisite for the sensitivity achievable with liquid xenon dark matter detectors beyond the current generation. Since Ar and Kr have similar laser cooling wavelengths, the appar ... [Rev. Sci. Instrum. 84, 093105 (2013)] published Thu Sep 26, 2013.

In this paper, an easily implementable adaptive optics system (AOS) based on a real-time field programmable gate array (FPGA) platform with state-space multichannel control programmed by LabVIEW has been developed, and also integrated into a laser focusing system successfully. To meet the requiremen ... [Rev. Sci. Instrum. 84, 095112 (2013)] published Mon Sep 23, 2013.
