    Abstract: A laser pulse includes a flat top shape. Another aspects provides a method and system for creating laser pulse amplification with a flat top and/or square shape, by only using phase modulation. In yet another aspect, a method and system create a flat top and/or square-shaped laser pulse in a reversible manner such that the stretched spectrum can be recompressed to their original duration with essentially no loss of pulse energy. A further aspect includes a method of making a fixed optic capable to creating flat top or square pulse amplification.

    Abstract: The disclosure relates to an irreversible dosimetric shock-detection substrate as well as related articles and methods. The shock-detection substrate incorporates a plurality of microcapsules serving as an irreversible means for detecting impact on the substrate. A shock above a characteristic threshold level experienced by the substrate induces an irreversible detectable change associated with the microcapsules upon shock-induced rupture. The irreversible detectable change provides a tamper-proof and non-electronic means for detecting a shock or impact. The shock-detection substrates can be incorporated into a variety of articles and used in a variety of settings, for example to monitor personal safety, to monitor article integrity, to monitor the end of the useful life of the shock-detection substrate itself, or in any other setting where it is desirable to irreversibly detect and/or localize a shock event.

    Abstract: The disclosure relates to materials and articles that provide an irreversible history of compression forces and torques experienced by the materials and articles. The disclosure relates more particularly to an multiple impact level detection assembly as well as related articles and methods. The multiple impact level detection assembly provides distinct impact patterns depending on the impact force and direction (for torqueing motions) received by the detection assembly. The detection assembly can be incorporated into a variety of articles and used in a variety of settings, for example to monitor personal safety in a protective garment such as a helmet. The detection assembly incorporates an impact detection medium (e.g., a plurality of microcapsules with an indicator therein), which can serve as an irreversible means for detecting impact on the assembly via a relief substrate incorporated into the assembly.

    Abstract: An adaptive laser system for ophthalmic use is provided. In another aspect, a relatively inexpensive laser is employed. In another aspect of the present system, non-linear optical imaging uses multiphoton fluorescences and/or second harmonic generation, to create three-dimensional mapping of a portion of the eye in combination with automated feedback to assist with a surgical operation. In a further aspect of the present system, the patient interface uses laser induced markings or indicia to aid in focusing and/or calibration. Still another aspect employs temporal focusing of the laser beam pulse.

    Abstract: The disclosure relates to piezoelectric apparatus containing ionic liquids. The piezoelectric apparatus includes a chamber defining an internal volume containing an ionic liquid therein. The ionic liquid can generate a voltage or current upon application of force to the chamber or cell, thus exhibiting a piezoelectric effect. The ionic liquid also can deform upon application of a voltage to the ionic liquid, thus exhibiting a converse piezoelectric effect. The piezoelectric apparatus further includes first and second electrodes in contact with the ionic liquid at first and second locations, such as at opposing locations in the chamber with the ionic liquid positioned between the electrodes. The piezoelectric apparatus, depending on whether it is configured to exhibit a piezoelectric effect or a converse piezoelectric effect, can form or otherwise be a component of various energy or sensing devices, such as an energy harvester, force sensor, piezo-pneumatic device or actuator, optical sensor, etc.
