| 20080219622 | OPTICAL FIBRE COUPLING SYSTEM - An optical fibre coupling structure comprising an optical fibre having an elongate input surface and shaped so that the diameter of the core of the fibre reduces in one dimension away from the input while increasing in the other dimension away from the input to form respective convergent and divergent surfaces, towards an output which is more circular than the input. | 09-11-2008 |
| 20080219299 | OPTICAL FIBRE LASER - A fibre laser is disclosed comprising a single mode or low-order-mode cladding pumped fibre laser oscillator or preamplifier, a cladding pumped fibre laser power amplifier to guide multiple transverse modes, wherein an output from the oscillator or preamplifier is applied through a mode mixing means to the power amplifier. The laser power amplifier is of greater core and cladding diameter than the oscillator or preamplifier, thus enabling lower brightness pump sources to be employed. | 09-11-2008 |
