TL;DR: In this article, the recombination times of photo-excited free charge carriers in heavily doped and highly compensated germanium are studied by a time-resolved pump-probe experiment at a frequency of ∼3 THz.

R.Kh. Zhukavin,K. A. Kovalevskii,Sergey M. Sergeev,Yu. Yu. Choporova,Yu. Yu. Choporova,V. V. Gerasimov,V. V. Gerasimov,V. V. Tsyplenkov,Boris A. Knyazev,Boris A. Knyazev,N. V. Abrosimov,S.G. Pavlov,V.N. Shastin,Harald Schneider,N. Deßmann,O. A. Shevchenko,Nikolay Vinokurov,G. N. Kulipanov,Heinz-Wilhelm Hübers +18 more
TL;DR: In this article, the relaxation times of antimony donors in unstrained and strained germanium uniaxially compressed along the crystallographic direction were measured at cryogenic temperatures using a single-wavelength pump-probe setup using radiation from the Novosibirsk free electron laser (NovoFEL).

Laser-induced alteration of Raman spectra for micron-sized solid particles
Ute Böttger,S.G. Pavlov,N. Deßmann,Franziska Hanke,Franziska Hanke,Iris Weber,Jörg Fritz,Heinz-Wilhelm Hübers,Heinz-Wilhelm Hübers +8 more
TL;DR: In this paper, the temperature-induced alteration of Raman spectra from micron-sized polycrystalline solid particles was investigated by comparing the results of different laser intensities and ambient temperatures.

Competing Inversion-Based Lasing and Raman Lasing in Doped Silicon
Sergey Pavlov,N. Deßmann,Britta Redlich,A. F. G. van der Meer,Nickolay Abrosimov,Helge Riemann,R.Kh. Zhukavin,V.N. Shastin,Heinz-Wilhelm Hübers,Heinz-Wilhelm Hübers +9 more
TL;DR: In this article, an optically pumped laser where photons are simultaneously generated by population inversion and by stimulated Raman scattering in the same active medium, namely crystalline silicon doped by bismuth (Si∶Bi), is presented.
