The first implementation of fitting X-ray Bragg diffraction profiles from strained multilayer crystals at a remote web-based X-ray software server is presented. The algorithms and the software solutions involved in the process are described. The suggested technology can be applied to a wide range of scientific research and has the potential to promote remote collaborations across scientific communities.

We report interband cascade vertical-cavity surface-emitting lasers (ICVCSELs) that operate in pulsed mode at temperatures up to 70 °C. Their emission at λ ≈ 3.4 μm extends considerably the previous longest wavelength of 3.0 μm for an electrically-pumped vertical-cavity surface-emitting laser operating at room temperature. The output from mesas having diameters ranging from 30 to 60 μm (with emission aperture diameters of 20–50 μm) is circularly symmetric, and the threshold current densities at T = 25 °C are as low as 390 A/cm2. However, the differential slope efficiencies are low, e.g., ≤50 mW/A at T = 25 °C, due to loss in the top and bottom mirrors and reduced current efficiency. The smallest device operates in a single spectral mode despite having an emission aperture much wider than the wavelength.
