Method for beam steering compensation in an ultra-high power liquid laser

Patent Ault, Earl R [Livermore, CA]

Thermally induced distortion of the optical wavefront caused by heating of the laser media by waste heat from the excitation process and absorption of laser radiation creates optical phase errors. A system generates an error signal derived from the optical phase errors. The error signal is fed back to the power supplies driving semiconductor diodes that excite the lasing liquid thereby introducing an electrically controllable wedge into the optical cavity to correct the optical phase errors.

Means and method for characterizing high power, ultra short laser pulses in a real time, on line manner

Patent Veligdan, James T [Manorville, NY]

An ultra short (<10 ps), high power laser pulse is temporally characterized by a system that uses a physical measurement of a wavefront that has been altered in a known manner. The system includes a first reflection switch to remove a portion of a pulse from a beam of pulses, then includes a second reflection switch, operating in a mode that is opposite to the first reflection switch, to slice off a portion of that removed portion. The sliced portion is then directed to a measuring device for physical measurement. The two reflection switches are arranged with respect to eachmore » « less

Method to determine the position-dependant metal correction factor for dose-rate equivalent laser testing of semiconductor devices

Patent Horn, Kevin M.

A method reconstructs the charge collection from regions beneath opaque metallization of a semiconductor device, as determined from focused laser charge collection response images, and thereby derives a dose-rate dependent correction factor for subsequent broad-area, dose-rate equivalent, laser measurements. The position- and dose-rate dependencies of the charge-collection magnitude of the device are determined empirically and can be combined with a digital reconstruction methodology to derive an accurate metal-correction factor that permits subsequent absolute dose-rate response measurements to be derived from laser measurements alone. Broad-area laser dose-rate testing can thereby be used to accurately determine the peak transient current, dose-rate responsemore » « less

Miniature device for ultra high sensitivity and stability probing in vacuum

Patent Pan, Xiaoqing; Blum, Thomas F.; Xu, Mingjie; ...

The present disclosure relates to in situ transmission electron microscope (TEM) holders with improved stability and electrical sensitivity. The holders feature a front bearing seal and a rear bearing seal which allow the holders to achieve high sensitivity, high stability, large range of motion and high vacuum isolation. The bearings use a PEEK insulating disk as a pivot point for translation and tilting motion, and use O-rings to dampen vibrations, provide electrical and vacuum insulation, and to set a grabbing force between the bearing and the probe.

Ultra-flat optical device with high transmission efficiency

Patent Czaplewski, David A.; Lopez, Daniel; Roy, Tapashree

An optical device includes a nanostructured transparent dielectric film, which is a Huygens metasurface. The Huygens metasurface imparts a phase change to light propagating through or reflecting from the surface. The phase change can be achieved by means of a resonant interaction between light and the Huygens resonators, resulting in a controllable phase change of 0 to 2π with approximately 100% light transmission characterized by a below 0.1 dielectric loss tangent of delta and with the height of the resonators less than the wavelength of light. In one embodiment, the metasurface includes titanium dioxide, but many materials or stacks ofmore » « less
