We report a home-built external cavity diode laser (ECDL), using a diode whose front facet is not antireflection (AR) coated, that has a mode-hop-free (MHF) tuning range greater than 140 GHz. We achieved this by using a short external cavity and by simultaneously tuning the internal and external modes of the laser. The general applicability of the method, combined with the compact portable mech...
A versatile, low-cost, digital signal processor (DSP) based lock-in module with external reference is described. This module is used to implement an industrial spectrophotometer for measuring spectral transmission and reflection of automotive and architectonic coating glasses over the ultraviolet, visible and near-infrared wavelength range. The light beams are modulated with an optical chopper....
The collaboration between the Solar Energy Research Institute of Singapore (SERIS), Trina Solar and ANU is progressing well, and ANU has already developed all-back-contacted (ABC) silicon wafer cells with best one-sun efficiencies of 21.2% and 22.1% on FZ material, when measured with the aperture areas of 16 cm (includes busbars) and 13 cm (excludes busbars) respectively. This paper presents th...
A study of the diffraction an electromagnetic wave on a dielectric coating with diaphragm over infinite waveguide antenna array has been carried out. The metal is located at some distance from surface array. influence geometric dimensions and its grating modulus reflection coefficient incident in waveguides investigated. Dielectric coatings different values constant are considered.
In paper the problem of reflection and refraction a plane harmonic sound wave by homogeneous isotropic elastic plate with an continuously inhomogeneous anisotropic coating is considered. It assumed that adjoin to ideal fluids. The propagation small perturbations in fluid case steady state oscillations described Helmholtz’s equation. waves uniform scalar vector equations for longitudinal transve...
Introduction: Nursing education should develop autonomy, critical thinking, open-mindedness and sensitivity to others. Reflection seems to be an effective strategy for developing such capabilities in nursing. Therefore, this narrative review study was carried out to explore reflection in nursing education. Methods: Using keywords like reflecting, reflection and nursing reflection, FarsiandEngl...
