We report a continuous-wave Ti:sapphire laser with an output power of 1.03 W, achieved with two low-cost single-emitter diode pumps, both of blue wavelength (448 and 468 nm). Using a novel strategy of combining blue-wavelength pumping with a long, low-doping Ti:sapphire crystal, we maximise the available pump power while minimising deleterious effects associated with blue pump wavelengths, demonstrating Watt-level output powers.

In this study, the two-phase pressure drop in a one-sided high-heat-loaded screw tube was analyzed under subcooled flow boiling conditions. When the loaded heat flux is gradually increased under one-sided heating conditions, although the pressure drop changes slightly in the single phase, it starts to increase when loading above the onset of significant void (OSV) heat flux.

Producing secure software is challenging. The poor usability
of security Application Programming Interfaces (APIs) makes this even
harder. Many recommendations have been proposed to support developers
by improving the usability of cryptography libraries and APIs; rooted in
wider best practice guidance in software engineering and API design. In
this SLR, we systematize knowledge regarding these recommendations.

The data here support the retrieval results presented in the submitted paper in IEEE Transactions on Geoscience and Remote Sensing, 'First TROPOMI Retrieval of Aerosol Effective Height using O4 Absorption Band at 477 nm and Aerosol Classification'.
The aerosol effective height (AEH) was retrieved from TROPOMI measurements based on the O4 absorption at 477 nm. The AEHs were retrieved over Northeast Asia, South Africa, and Sahara Desert during some case study periods.

In this simulation, the DC voltage of the matrix converter is derived using a three-phase linear load as a sample. It shows that the voltage used by the three inverters and the average over the switching period are always the same. It also shows that when the load is constant, the DC current of the inverter is also constant.

In this simulation, the phase difference of the signals a, b, and c in the paper is changed to 0 in 0.1 seconds from the state where the phase is 90 degrees different from the input voltage. The input current phase is the same as the above signal. Since the output voltage gradually increases, it can be seen that the DC voltage of the matrix converter increases as the phases of a, b, and c become closer to the input voltage phase. Strictly speaking, it is proportional to cosθ as described in the paper.
