摘要： A laser is disclosed, which is suitable for efficient generation of continuous-wave laser light having a wavelength of about 400 nm or less. The short-wavelength light is generated by first frequency-doubling a fundamental wave, and then sum-frequency mixing the frequency-doubled wave and the fundamental wave. The non-linear interactions are effected by means of quasi-phasematching structures inside a resonant cavity where the fundamental wave is circulating. The sum-frequency mixing is effected using second or higher order quasi-phasematching, which allows for wider domains to be inverted for the quasi-phasematching structure compared to first order quasi-phasematching. Preferably, the sum-frequency mixing is effected using periodically poled stoichiometric lithium tantalate (PPSLT) for second or third order quasi-phasematching.

摘要： A method for processing a time domain reflectometry (TDR) signal used to determine at least one process variable for a material in a tank, wherein said TDR signal has been generated by a radar level gauge system comprising a pulse generator, a probe extending into the tank for guiding the pulse, and a receiver for receiving said TDR signal, and wherein the TDR signal comprises at least a surface reflection pulse caused by an interface between different materials in the tank, and an interfering pulse caused by a transition between the pulse generator and the probe. The method comprises obtaining a first sampled TDR signal with an amplification such that the interfering pulse is unsaturated, determining a compensation pulse signal using a previously stored pulse shape and a current pulse position, subtracting said compensation pulse signal from the first sampled TDR signal, determining if a surface reflection occurs in a zone where said interfering pulse has a significant interfering effect on any surface reflection pulse occurring in this zone, and, if no surface reflection occurs in this zone, updating the current pulse position.

摘要： A lens arrangement for transforming a divergent, generally astigmatic laser beam from a diode laser into a beam having a high degree of rotational symmetry is disclosed. The arrangement comprises, in series, a first cylindrical gradient index lens arranged with its principal axes parallel to the principal axes of the astigmatic laser beam; a second cylindrical gradient index lens arranged with its principal axes parallel to the principal axes of the astigmatic laser beam; and a third cylindrical gradient index lens arranged with its principal axes rotated 45 degrees with respect to the principal axes of the astigmatic laser beam. The first and the second gradient index lenses have such refractive powers that both the fast and the slow axis of the astigmatic laser beam are converged to a focus inside the third gradient index lens.
