Abstract Loss of reflectivity in the Arctic and the wider cryosphere is known to increase global temperature rise through an ice‐albedo feedback loop, which has the potential to lead to loss of summertime ice cover in the Arctic Ocean, and to accel

We explore the full parameter space for laser operation and compile guidelines for building improved Ge lasers, especially for continuous wave applications. We present laser emission from p-type Ge lasers with small volumes at high repetition rates a

We have measured the spectrum of stimulated far-infrared emission from Be- and Zn-doped germanium single crystals in crossed electric and magnetic fields. The spectrum consists of broad radiation bands in the frequency range of $40--130{\mathrm{cm}}^

Using molecular-beam epitaxy, we have fabricated p-n tunnel junctions lattice matched to GaAs substrates that consist of highly C-doped Ga0.93In0.07As on the p side, and highly Si-doped Ga0.93In0.07N0.02As0.98 on the n side. The introduction of N on

We demonstrate narrow linewidth emission from p-Ge terahertz lasers at low magnetic fields where intervalence-band emission dominates. The volume of these laser crystals is 32 mm3, which is one order of magnitude smaller than the lasers for which the

We have fabricated a copper-doped germanium laser using copper diffusion into commercially available pure germanium. The spectrum and the emission pulses of this laser were investigated. Active mode locking was achieved with pulse lengths of 160 ps a

We measured laser emission from Be-doped Ge crystals with intercontact distances as small as 0.5 mm. An improved heat sink allowed a twofold increase of the laser duty cycle to 5%. We also report the measurements of THz emission from small Be-doped G

We demonstrate operation of p-Ge far-infrared lasers with a planar contact geometry. The smallest laser crystal with this geometry has a maximum pulse length of 22 μs, which is 10% longer than the pulse length of comparably doped lasers with the tra

While much work has focused on simulation and measurement of plasmon resonances in noble metal nanostructures, usually the simulation tool is used as a confirmation of experimental results. In this work we use a finite difference time domain (FDTD) t
