    Abstract: Non invasive in-vivo measurement of composition of a tissue within a part of a human or animal subject is carried out by detecting a Raman spectral characteristic in light scattered through the part using a transmission, rather than a backscattering geometry. The technique is applied to the detection of calcifications in human breast tissues.

    Abstract: An optical apparatus comprising a first mirror (12), a second mirror (14), and at least one support (30) for holding the second mirror in substantially a predetermined position relative to said first mirror (12), wherein said at least one support (30) comprises at least one actuator (32) arranged to adjust the position of the second mirror (14), and said optical apparatus further comprises at least one light source (40a-40-c) rigidly fixed to the first mirror (12) in a predetermined orientation for providing a beam of light (42a-42c) directed at said second mirror (14), at least one corresponding alignment sensor (46a-46c) for detecting the beam of light (44a-44c) reflected from said second mirror (14), and arranged to provide an output signal indicative of the position of the incident reflected beam, and a controller (50) arranged to receive said output signal, and to thereby control said actuator (32) to adjust the position of the second mirror (14).

    Abstract: The pulse stretcher 100 comprises; a first diffraction grating G1 arranged to receive and disperse a seed laser pulse; a transmission diffraction grating G2 arranged to collimate and transmit the pulse to a reflector BM, the reflector reflects the pulse back through the pulse stretcher via the transmission diffraction grating. The pulse stretcher provides better phase noise performance of the output pulse, and therefore a reduction in the noise floor to improve contrast pedestal and provide high power ultrashort laser pulses.

    IPC: B23K26/36 ,  B23K26/00

    Abstract: A method of reducing the photoelectron yield (PEY) and/or the secondary electron yield (SEY) of at least part of an apparatus, the method comprising the steps of providing an apparatus, and ablating material from a metal surface of the apparatus using a pulsed laser to produce an array of periodic structures in the metal surface and thereby reducing the PEY and/or SEY of the metal surface. The apparatus is shown to be a vacuum chamber, a particle accelerator, a radio frequency waveguide, a detector and a spacecraft. Also shown is a method performed in the presence of a reactive gas such that the metal surface is caused to react with the reactive gas.
