摘要： In accordance with embodiments of the present disclosure, a flextensional transducer for underwater operation includes a driving element and a stave. The stave is made from a material with elastic properties and has a porous structure. The porous structure is adapted to be modelled such that when in use, said porous structure of the stave is of an arbitrary alignment with respect to, for instance, the driving element, and has a degree of porosity. The degree of porosity is such that the elastic properties and vibrational frequency response of the stave can be customised with respect to its intended use.

摘要： A side pumped laser comprises an elongated gain medium (10) provided between an output coupler (20) and a counter reflector (15) and a pump source (65) configured to provide radiation to the gain medium (10) along a side axis of the gain medium, wherein the laser is configured such that radiation from the pump source is directly incident on the gain medium; and the pump source is provided proximate, adjacent or in contact with the gain medium. The laser material and compositions, geometries and dimensions are designed to both maximise laser performance and to permit the use of construction techniques commonplace in the production of equipment designed for optical telecoms systems to facilitate low cost high volume and miniaturisation. The elongated gain medium (10) may have a polygonal cross-section with a non-coated side surface (55) receiving pump light emitted by a laser diode bar (65) while the other, non-emitting surfaces are coated with for example a gold coating (60) for pump light recycling and cooling of the gain medium by heat conduction. The counter reflector (15) may be provided on one facet of a passive Q-switch (30) and the output coupler (20) on a facet (50b) of the gain medium (10).
