Experiments on frequency doubling of 1064 nm and 1053 nm radiation with non-phase-matched and (close to) phase-matched germania-doped silica fibres are reported. The greatest conversion efficiencies are obtained with non-phase-matched fibres that are

Detailed measurements of the ultraviolet absorption spectra of germanosilicate preforms, multimode and single‐mode fibers are presented. Significant differences between the spectra of preforms and fibers are revealed and these differences are thoug

In this paper we present the performance of TM3+ and Pr3+-doped ZBLAN fibre lasers at blue, green, and red wavelengths, both pumped efficiently with the output of Yb3+-doped silica fibre lasers.1

Ar ion beam sputtering has been used to deposit fluoride glasses films up to a micron in thickness on silica and silicon substrates, Fluorozirconate films were found to be dark in colour, attributed to the presence of reduced chemical species. Fluoro

Ever since Osterberg and Margulis1 reported the growth of second-harmonic generation in optical fibres, and the observation by Stolen and Tom,2 the question has remained: how is the initial frequency doubled light generated? In particular Stolen and

This paper reports the first demonstration of reflection gratings, operating at the important telecommunications wavelength of 1.5 m, that have been written directly into germanosilicate fibers with an ultraviolet source. Although Meltz et al.1 have

The defect-induced one-phonon infrared absorption in natural diamond can be divided into a number of overlapping components. The computational method of extracting the spectral shapes of these contributions is described. The A and B components are as
