Abstract: A compact high average power mid infrared range laser for ultrasound inspection. The laser comprises one of a Nd:YAG or Yb:YAG laser pumped by a diode at 808 nm to produce a 1 micron output beam. The 1 micron output beam is directed to an optical parametric oscillator where the beam wavelength is converted to 1.94 microns and conveyed to a mid infrared emission head. The emission head comprises one of a Ho:YAG or Ho:YLG laser optically coupled with a second optical parametric oscillator. The second optical parametric oscillator forms a generation output beam for creating ultrasonic displacements on a target. The generation output beam wavelength ranges from about 3 to about 4 microns, and can be 3.2 microns.

Abstract: A method subsequently reinforces injection-molded transporters such as plastic pallets, which have support feet disposed on their underside, at least at the corners, and a groove for inserting a reinforcement profile between two support feet that stand diagonally opposite one another, and the two ends of the groove are formed by pockets shaped to correspond to the profile cross-section, disposed in the region of the support foot assigned to the groove end, in each instance. After completion of the pallet, the distance between the two pockets is increased via elastic deformation of the pallet. Afterwards, the reinforcement profile is laid into the groove, and one end of the profile is laid into one of the pockets. Thereafter, the deformation is canceled out and the pallet returns to the relaxed original state, and in this connection the other end of the reinforcement profile also dips into the corresponding pocket.
