We present our first results on the fabrication of new, high-performance polyimide coatings. The key components of the coatings are polyimides containing various cardo and/or fluoroalkylene groups, which allows the coatings to retain their high-tempe

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

The visible and near-IR absorption and luminescence bands of bismuth-doped silica and germanosilicate fibres have been measured for the first time as a function of temperature. The temperature-dependent IR luminescence lifetime of a bismuth-related a

The first fibre preforms with a Pb-doped silica core, free of other dopants, have been produced using chemical vapour deposi- tion. The preforms have been used to fabricate holey optical fibres. The spectroscopic properties of the fibres have been st

Photochemical reactions induced in the glass network of an ytterbium-doped fibre core by IR laser pumping and UV irradia- tion have been investigated by analysing absorption and lumines- cence spectra. We have performed comparative studies of the pho
