摘要： This invention relates to optical fibres, fibre lasers, fibre laser arrays and sensor systems comprising fibre laser arrays. Conventional fibre laser sensor arrangements comprise a plurality of fibre lasers arranged in series along a length of optical fibre. A pump light source is located a one end of the fibre and supplies pump light energy to each of the fibre lasers in turn. Such sensor systems experience a number of disadvantages. Firstly, there is an uneven distribution of pump power along the length of the fibre which effectively limits the number of laser devices that can successfully be incorporated into the optical fibre array. Secondly, the manner in which existing sensor systems are constructed often results in back reflections, optical losses and mechanical weaknesses. The present invention provides a fibre laser which mitigates the above problems with fibre laser sensor arrays.

摘要： Musical instrument sound detection is achieved using a fibre optic acoustic sensor that is sensitive to sound generated by a musical instrument. Sound waves falling on the acoustic sensor cause at least one property of electromagnetic radiation transmitted through the fibre optic to vary. This variation is indicative of the sound generated by the musical instrument and can be detected by an electromagnetic radiation detector.
