title: Development of a 443 nm diode laser-based differential photoacoustic spectrometer for simultaneous measurements of aerosol absorption and NO2

description: The experimental data are obtained by the differential photoacoustic spectrometer established in this paper. A novel photoacoustic resonator was designed and employed in the D-PAS for controlling a large flow rate, improving response time, and keeping the flow noise at a low level.

description: We demonstrate the laser performance of a 968 nm LD side-pumped Er:LuYSGG crystal rod by optimizing the cavity length and output coupler transmission. The maximum output power of 14.84 W is obtained at 150 A, 150 Hz, and 200 μs, corresponding to a slope efficiency of 17.2%. Under the high frequency of 500 Hz and short pulse width of 60 μs, an average output power of 7.27 W is achieved, corresponding to a slope efficiency of 7.1%. Additionally, the beam quality factors Mx2/My2 of 7.04/7.12 are also determined at 150 Hz and the average output power of 11.33 W. These results can provide valuable references for promoting the development of 2.7-3 μm lasers.

title: Humidity enhanced N2O photoacoustic sensor with a 4.53 μm quantum cascade laser and Kalman filter

description: A high-sensitivity N2O photoacoustic sensor using a 4.53 μm quantum cascade laser was developed and described. The 2.3% water vapor was added to the analyzed sample to improve the vibrational-translational (V-T) relaxation rate of N2O molecule transition, and therefore enhance the N2O photoacoustic signal. High performance with a minimum detection limit of 28 ppbv in 1 second and a measurement precision of 34 ppbv have been achieved, respectively. Without sacrificing the time resolution of the system, the Kalman adaptive filtering improves the measurement precision of the system by 2.3 times. The ability of the N2O photoacoustic sensor was demonstrated by continuous measurement of atmospheric N2O concentration for a period of 7 hours.

title: Allopolyploid origin and niche expansion of Rhodiola integrifolia (Crassulaceae)

description: The dataset includes all supplementary files and sequence data set used in the article 'Allopolyploid origin and niche expansion of Rhodiola integrifolia (Crassulaceae)'. The study used phylogeny-based approach to show that R. integrifolia possesses alleles from both R. rhodantha and R. rosea. Dating analysis showed that the hybridization event that led to R. integrifolia occurred ca. 1.67 Mya and niche modeling analysis showed that at this time, both R. rosea and R. rhodantha may have been present in Beringia, providing the opportunity for the hybridization event. We also found that the niche of R. integrifolia differs from that of its progenitors in both niche breadth and optimum.

description: We demonstrate the laser performance of high repetition frequency on a 970 nm laser diode (LD) side-pumped Er:YSGG crystal rod with concave end faces. The laser performance under different repetition rates and pulse widths was studied with an optimal cavity length. The maximum average output power of 11.81 W operated at a repetition frequency of 500 Hz and 2.794 μm was achieved, corresponding to the slope efficiency of 10.49%. In addition, the beam quality factors M2x/M2y of 7.01/7.10 and far-field divergences Θx/Θy of 9.15/9.18 mrad were also obtained under the high repetition frequency of 500 Hz. These results show that the LD side-pumped Er:YSGG laser crystal rod with concave end faces has the potential of being operated under high repetition frequency.
