Laser interferometers have demonstrated outstanding measuring performances for high precision positioning or dimensional measurements in the precision industry, especially in the length measurement. Due to the non-common-optical-path structure, appreciable measurement errors can be easily induced un ... [Rev. Sci. Instrum. 84, 053105 (2013)] published Tue May 14, 2013.

An optical rotation measuring system using optical null methods is set up. The system is based on a step-motor rotating stage structure and a modulated laser, which both are controlled by digital signal processor. By introducing a curve-fitting method, the optical rotation angle is obtained from the ... [Rev. Sci. Instrum. 84, 053104 (2013)] published Mon May 13, 2013.

Tsinghua Thomson Scattering X-ray Source (TTX) is the first-of-its-kind dedicated hard X-ray source in China based on the Thomson scattering between a terawatt ultrashort laser and relativistic electron beams. In this paper, we report the experimental generation and characterization of the first har ... [Rev. Sci. Instrum. 84, 053301 (2013)] published Wed May 8, 2013.

We demonstrate a high-performance HeNe laser feedback interferometer (HLFI) based on a birefringence feedback cavity scanned by a piezoelectric transducer (PZT). The PZT scanning technique leads to a significant improvement in the HLFI's anti-jamming capability. The null drift under general laborato ... [Rev. Sci.

In this paper, an innovative method for CMM (Coordinate Measuring Machine) self-calibration is proposed. In contrast to conventional CMM calibration that relies heavily on a high precision reference standard such as a laser interferometer, the proposed calibration method is based on a low-cost artef ...

The motional Stark effect with laser-induced fluorescence diagnostic (MSE-LIF) has been installed and tested on the National Spherical Torus Experiment (NSTX) at the Princeton Plasma Physics Lab. The MSE-LIF diagnostic will be capable of measuring radially resolved profiles of magnetic field magnitu ... [Rev. Sci. Instrum. 84, 043110 (2013)] published Mon Apr 29, 2013.

In this study, the applicability of commonly used Damage Frequency Method (DFM) is addressed in the context of Laser-Induced Damage Threshold (LIDT) testing with pulsed lasers. A simplified computer model representing the statistical interaction between laser irradiation and randomly distributed dam ... [Rev. Sci. Instrum. 84, 045108 (2013)] published Fri Apr 26, 2013.

Two phase-coherent Raman laser beams with a frequency offset of 6.835 GHz were generated by sideband injection-locking technique. A master diode laser was phase-modulated at 6.835 GHz by a fiber electro-optic modulator. A slave diode was injection-locked to the 1 sideband of the phase-modulated beam ... [Rev. Sci.

In this paper, a new method employing Raman spectroscopy to determine thermal conductivity (TC) and thermal contact resistance (TCR) of an individual fiber was developed. Laser absorption is accounted for, but there is no need to be determined in this method. The local temperatures along the fiber l ... [Rev. Sci.

The neutron spectrum produced by deuterium-tritium (DT) inertial confinement fusion implosions contains a wealth of information about implosion performance including the DT yield, ion-temperature, and areal-density. The Magnetic Recoil Spectrometer (MRS) has been used at both the OMEGA laser facilit ... [Rev. Sci. Instrum. 84, 043506 (2013)] published Thu Apr 18, 2013.
