摘要： A high power amplifier silica glass material is provided wherein photo darkening due to high optical flux is reduced considerably. The conventional counter part amplifier and laser based on conventional silica glass material have a problem in that their characteristics are deteriorated with the elapse of time due to photo darkening. The new fibre amplifier and laser silica glass material shows through reduction of the non-binding oxygen electron concentration less photo darkening. This is achieved through hydrogen or deuterium load of the amplifier glass material or by co-doping with phosphorous P 4 O 8-x (OH) 4+2x , (0 x 2).

摘要： The invention relates to an optical waveguide laser comprising a) an active region formed over a length of the optical waveguide, comprising an excitable material emitting light in response to stimulation by pump light thereby defining an optical gain profile and the excitable material comprises Tm; b) a frequency discriminated feedback element adapted to select a single longitudinal lasing mode by coordination with the frequency response of the optical gain of the excitable material; and c) a polarisation asymmetry element adapted for selecting a single polarisation mode of a given longitudinal mode by selectively suppressing propagation of the other polarisation mode of said longitudinal mode. The object of the present invention is to provide relatively simple, compact and economic lasers for single-frequency operation in the wavelength range of 1.7 um to 2.2 um; in particular for a number of applications, including spectroscopy and for eye-safe optical sources in sensing and in LIDAR, etc.

摘要： The present invention relates to an optical component comprising an acceptance fibre, e.g. a photonic crystal fibre, for propagation of pump and signal light, at least one pump delivery fibre and an optical assembly, e.g. a reflector element, that directs pump light from the pump delivery fibre into the accep-tance fibre. The pump delivery fibre furthermore has a guiding structure (3012, 3013) embedded within the pump core (3014) in order to collect light leaking into the fibre, thereby avoiding damage to the pump source. It is an object of the invention to provide a fibre coupler for coupling at least one light source into a multi-clad (e.g. double clad) optical fibre, which has practical advantages with respect to handling, loss and back reflection.
