title: A dataset of investigation on the mechanical, thermal properties, and refractive index of Er,Pr:GYSGG laser crystal

description: We investigate the mechanical, thermal properties and refractive index of Er,Pr:GYSGG crystal with excellent radiation-resistant ability grown by the Czochralski method. The X-ray rocking curve and the optical homogeneity reveal that the Er,Pr:GYSGG crystal possesses high crystalline and optical quality. The crystal density is measured to be 6.03 g·cm−3 by the Archimedes method. The Mohr's hardness is obtained to be 6.42, indicating that the Er,Pr:GYSGG crystal is conducive to being processed compared with Er:YSGG crystal. The thermal specific, thermal conductivity and thermal expansion coefficient are determined to be 0.52 J·g-1·K-1, 5.35 W·m-1·K-1 and 8.50×10-6 K-1, respectively. The refractive indices corresponding to a few distinct wavelengths are determined by the method of minimum deviation angle, which are used to fit the refractive index curve in the range of 320-3000 nm through the Sellmeier dispersion equation. All these results are of great significance for the further research and laser application of the Er,Pr:GYSGG crystal.

title: A dataset of Growth, structure and spectroscopy of Ho,Pr:LuYSGG mixed crystals for 2.9 μm emission

description: A series of Ho and Pr doped LuYSGG laser crystals were successfully grown by Czochralski method. X-ray rocking curves indicate their high crystalline quality. Crystal structure and basic parameters are provided by XRD and Rietveld refinement. Combining density functional theory, the bandgaps of YSGG and LuYSGG are calculated to be 3.497 and 3.483 eV, respectively. Particularly, the J-O parameters and emission spectra suggest the LuYSGG is more suitable as host for Ho3+ ions and could achieve better 2.9 μm emission than YSGG. Meanwhile, the luminescent decay curves show the deactivated Pr3+ ion can greatly narrow the lifetime gap between the 5I6 and 5I7 energy levels, which can eventually attenuate effect of self-termination phenomenon on the 2.9 μm emission.

title: A dataset of LD end-pumped Er,Pr:GYSGG single crystal fiber laser as a potential mid-infrared seed source applied in radiation environment

description: We demonstrate the influence of gamma-ray irradiation on the propagation loss and laser performance of an Er,Pr:GYSGG single crystal fiber (SCF). The size of SCF is f 0.75 mm×70 mm and the diameter fluctuation is less than 3.5%. The propagation loss coefficients of the samples are 0.07 and 0.09 dB cm-1 before and after irradiation, respectively, which is almost unaffected. The maximum output powers of 197 and 192 mW on the SCFs before and after irradiation are obtained under a 969 nm laser diode (LD) end-pumping, corresponding to the slope efficiencies of 8.1% and 7.9%, respectively. A very good beam quality factor Mx2/My2 of 1.11/1.13 is achieved. These results imply that the Er,Pr:GYSGG SCF laser can be used as a potential seed source for mid-infrared (MIR) multi-stage amplification laser apparatus applied in radiation environment.

title: Sensitive Detection of CH4 and CO2 Using Frequency-Division-Multiplexing Based Quartz-Enhanced Photoacoustic Spectroscopy
title: 基于频分复用石英音叉增强型光声光谱技术的CH4和CO2测量研究

description: A compact double-gas sensing system was reported for simultaneous sensitive CH4 and CO2 detection, this system combined quartz-enhanced photoacoustic spectroscopy (QEPAS) and frequency division multiplexing technique. Two continuous wave distributed feedback diode lasers operating at 1654 nm and 2004 nm were employed as the light sources. The photoacoustic signals were excited by simultaneously injecting sinusoidal modulation currents with independent frequencies near the resonant frequency of the QTF into the lasers，and were subsequently demodulated to obtain the corresponding second harmonic components of CH4 and CO2. The frequency-domain results showed no interference between the photoacoustic signals of the two gases. The relationships between CH4 and CO2 concentrations and the corresponding second harmonic signals have been calibrated, and linear correlation coefficients better than 0.994 were obtained. The system performance was further evaluated through Allan deviation analysis on CH4 and CO2 with given concentration. The minimum detection limits of CH4 and CO2 for the system were obtained as 0.58×10-6 and 1.32×10-6, corresponding to the normalized noise equivalent absorption coefficients (NNEA) of 7.2×10-9 cm-1W√Hz and 9×10-9 cm-1w√Hz, respectively.

title: Tearing mode stabilization by electron cyclotron resonant heating in EAST tokamak experiments

description: Tearing mode stabilization by electron cyclotron waves (ECWs) has been carried out inExperimental advanced superconductiong tokamak (EAST) experiments. The effects of theamount of ECW power and the radial wave deposition location on stabilizing the m/n = 2/1magnetic island are investigated, where m/n is the poloidal/toroidal mode number. The localheating is found to dominate the mode stabilization in these experiments. The stabilization ismore effective when the wave is deposited closer to the radial island location, as expected.With increasing ECW power, however, the tearing modes are not stabilized completely, andthe island width saturates at a finite width. Moreover, the island rotation frequency is found todecrease when the ECW deposition is close to the island such that the island width is reducedsignificantly. Using externally applied, rotating resonant magnetic perturbations to generateslowly rotating magnetic islands, the locked island stabilization by ECW has also beenstudied, and the island width reduction and nonuniform island rotation are observed when theisland’s center passes through the ECW deposition region
