LASER DEVICE

A laser device comprises a non-collinear optical parametric generator (OPG) and a pump wave source (4). The OFG comprises a non-linear crystal (1) fixedly mounted within the generator wherein the relative orientations of the pump wave (3) and each generated wave (5) to an optic axis (2) of the non-l...

More Information
Summary:A laser device comprises a non-collinear optical parametric generator (OPG) and a pump wave source (4). The OFG comprises a non-linear crystal (1) fixedly mounted within the generator wherein the relative orientations of the pump wave (3) and each generated wave (5) to an optic axis (2) of the non-linear crystal (1) are substantially such that a point of inflexion is produced in a tuning curve of wavelength versus pump wave orientation of one of the generated waves, such that a broadband spectral output is obtained. This device has many applications including an amplifier for an input seed wave in which the crystal dose not have to be rotated to match the wavelength of the seed wave; or as part of a continuously tuneable narrowband source.
