Publikováno v: Quantum Electronics. 42:925-930
We have studied processes initiated in the bulk of singlecrystal silicon by local excitation of its electronic subsystem with femtosecond IR laser pulses (λ = 1.2 μm, τFWHM = 250 fs). IR femtosecond interferometry has been used for the first time

Bismuth-doped optical fibres: A new breakthrough in near-IR lasing media
Autor: Evgenii M Dianov
Publikováno v: Quantum Electronics. 42:754-761
Recent results demonstrate that bismuth-doped optical fibres have considerable potential as near-IR active lasing media. This paper examines bismuth-doped fibres intended for the fabrication of fibre lasers and optical amplifiers and reviews recent r
