title: Effective diamond deposition on Ti:sapphire with Cr interlayer via microwave plasma chemical vapor deposition
title: Effective diamond deposition on Ti:sapphire with Cr interlayer via microwave plasma chemical vapor deposition

description: The application of diamonds for thermal management of solid-state lasers has recently attracted increasing interest. However, the problem of synthesizing highperformance diamonds has not been addressed, hindering the development of advanced heat management. Here, we deposited diamond by MPCVD method on a Ti:sapphire substrate to improve the thermal performance of the substrate by using a Cr interlayer, and the seeded Cr layer was effective in improving the adhesion between the diamondfilm and the substrate. The results were rationalized by using first-principles calculations, and it was shown that the stable interface adhesion was attributed to the strong carbon adsorption capability of the Cr surface, which favored the C-Cr bond formation at the interface. The catalysis of the Cr results in an increase in the nondiamond phase, impeding interface binding. To address this, ~0.2% of oxygen was used during the deposition process. Raman spectroscopy showed that the diamond film deposited on the Cr interlayers was under compressive stresses of 0.51 and 0.45 GPa, and the thermal diffusion coefficient increased by 17%. This enhancement in performance offers a promising potential for the fabrication of high-power solid-state laser heat spreaders using diamond films.

title: Spectral Performance of Yb3+-Doped Silica Fiber for 1018 nm Tandem-PumpingTechnology
title: 1018nm 同带泵浦用 Yb3+ 掺杂石英光纤光谱性能研究

description: The actual contents of Al and Yb in the samples were similar to the theoretical values, while the contents of P were slightly lower than the theoretical values due to the volatilization of P during the high temperature sintering process. The absorption spectra were measured by a PerkinElmer Lambda 950 spectrophotometer with the wavelength range of 190-1200 nm and a scan step of 1 nm. The fluorescence spectra were measured by a FLS920 fluorescence spectrometer with a xenon lamp at 896 nm as the excitation source and a scan step of 1 nm. The extra-red absorption spectra of the glass samples were measured by a Nicolet 6700 Fourier spectrometer. The Raman spectra were measured by a Horiba LabRAM HREvolution Raman spectrometer with a wavelength range of 200~1500 cm-1 and an excitation wavelength of 633 nm. The 2D-HYSCORE spectra of the samples were measured with a Swiss Bruker E580 pulsed EPR detector at 4K.

title: SpectralPerformanceofYb3+-DopedSilicaFiberfor1018nm Tandem-PumpingTechnology
title: 1018 nm同带泵浦用Yb 3+掺杂石英光纤光谱性能研究

description: The effect of Al3+ and P5+ on the absorption and fluorescence properties of Yb3+ doped quartz glass at 1018 nm was investigated for the first time in the world by using the sol-gel method combined with high temperature sintering of nanopowders. The normalized fluorescence intensity of Yb-P-doped quartz glass series at 1018 nm was significantly better than that of other series. Using Raman spectroscopy combined with ultra-low temperature electron paramagnetic resonance (EPR 4K), the coordination environment of Yb3+ was precisely resolved from the atomic scale in this paper. In the Yb3+-doped quartz glass, the coordination environment of Yb3+ is very different with the introduction of Al3+ and P5+, which is consistent with the effect pattern of Al3+ and P5+ on the spectral properties of Yb3+ at 1018 nm.

title: Automatic baseline correction method for the open-path Fourier transform infrared spectra by using simple iterative averaging

description: It’s necessary to remove the baseline from the spectra, which measured by open-path Fourier transform infrared spectrometry, for further spectral analysis such as qualitative and quantitative analysis. An automatic baseline correction method, the Iterative Averaging method, is presented. Baseline corrected by this method is accurate, and it also shows more precise than other methods when it is applied to Fourier Transform Infrared experimental spectra and simulated data. This method solves the key technology of the real-time on-line spectral analysis of OP-FTIR and improves the capability and adaptability of the unsupervised on-line system effectively.

title: Nanocrystalline Yb:YAG-Doped Silica Glass with Good Transmittance and Significant Spectral Performance Enhancements
title: Nanocrystalline Yb:YAG-Doped Silica Glass with Good Transmittance and Significant Spectral Performance Enhancements

description: In this study, Yb:YAG-nanocrystal-doped silica glass with high transmission and excellent spectral properties was successfully prepared using a modified sol–gel method. The X-ray diffraction (XRD), micro-Raman spectroscopy, electron paramagnetic resonance (EPR), transmission electron microscopy (TEM), and high-resolution TEM (HR-TEM) analyses confirmed that the Yb:YAG nanocrystals, with their low content, homogeneous distribution, and small crystal size, directly crystallized into the silica glass network without annealing treatment. In contrast with conventional microcrystalline glass having large particles (&gt;0.1 μm) and a large particle content, nanocrystalline glass with a homogeneous distribution and sizes of ~22 nm had higher optical transmittance and better spectral properties. Compared with Yb3+ doped silica glass without nanocrystals, the Yb:YAGnanocrystal-doped silica glass had a 28% increase in absorption cross-section at 975 nm and a 172% enhanced emission cross-section at 1030 nm without any changes in the spectral pattern of the Yb3+ ions in the silica glass. Meanwhile, the Yb:YAG-doped silica glass with large size and high optical quality was easily prepared. Therefore, the Yb:YAG-nanocrystal-doped silica glass is expected to be a promising near-infrared laser material.

title: Study on baseline correction methods for the Fourier transform infrared spectra with different signal-to-noise ratios

description: Removing the baseline from the spectra, which are measured by a Fourier transform infrared spectrometer(FTIR), is an important preprocessing step for further spectra analysis such as quantitative and qualitative analysis.An automatic baseline correction method named iterative averaging, which is based on the basic knowledge of moving average, is presented. We also compared it to other methods, such as rubber band, adaptive iterative reweight penalized least squares, automatic iterative moving average, and morphological weighted penalized leastsquares, using simulated and experimental spectra with different signal-to-noise ratios (SNRs) to evaluate the performance of these methods by performance metrics and to select an appropriate method to analyze FTIR spectra. Performance metrics such as root-mean-square error, goodness-of-fit coefficient, and chi-square are calculated.The iterative averaging method achieves the best results, which are judged by performance metrics values,when it is applied to the FTIR spectra with different SNRs. It also can correct the baseline of the FTIR spectraautomatically, and improve the capability and adaptability of the unsupervised online analysis of the FTIR system effectively
