An efficient, compact diode-laser-pumped 2.94µm Er:YAG laser operating at 1.5 W continuous output power in a TEM00 beam with M2<1.2 has demonstrated pulsed operation in the quasi-cw regime with energies up to 9 mJ. Power scaling and output beam fiber-coupling at 85% efficiency in a hermetic package will be described.
High quality photography on mobile phones in low light
"Sorry for the quality, mobile." Almost everyone makes excuses when publishing a photo taken with a camera phone. What are the problems taking good quality pictures with camera phones and is there a way to solve them and bridge the gap between camera phones and compact cameras?
The essence of photography is light. With its tiny lens, a ...
A new prototype imaging system based on ultrasound transmission through the object of interest--acoustical holography--was developed which incorporates significant improvements in acoustical and optical design. This system is being evaluated for potential clinical application in the musculoskeletal system, interventional radiology, pediatrics, monitoring of tumor ablation, vascular imaging and ...
Advanced Diagnostics, Inc. (ADI) has developed a technique using Diffractive Energy Imaging (DEI) to provide an accurate, non-ionizing method for continuously tracking biopsy needles. The method utilizes ultrasound to generate large field-of-view, high resolution, multi-planar images. Accurate, real-time biopsy guidance using DEI is possible by identifying the physical relationship between a ...
Although web technologies have broken down many traditional barriers to communication, not everyone has been able to participate fully in new communication channels. For millions of individuals with disabilities, accessing digital information is still challenging. Government agencies, advocacy groups, and businesses are working to improve accessibility for all web users, including individuals ...
This paper reviews features of solenoid lenses to focus high-current electron beams. It also discusses how to characterize spherical aberration with a numerical orbit code and how to employ scaling methods to organize simulations for maximum generality.
Emittance characterizes the degree of disorder in a charged particle beam. The transverse emittance parametrizes the thermal spread of transverse mo-mentum. Random motion results in an effective pressure that determines focusing forces necessary to confine a beam as well as the minimum spot size
of a focused beam. The text Charged Particle Beams1 gives a comprehensive review of definitions and ...
In this presentation, we compare the transmission charac- teristics between an octupole (o) and quadrupole (q) of similar inscribed radius when they are used as an ion pipe and as the collision cell in an MS/MS (QqQ and QoQ) system. Octupole dimensions were chosen such that the rods were large enough to accommodate reasonable sized screws, and to match the inscribed radius of the quadrupole. The ...
The growing intersection of wireless and consumer electronics over the last few years has made CES a must-attend event for mobile operators and equipment vendors. This year was no exception, as both AT&T and Verizon Wireless discussed their 4G network plans and new devices. Meanwhile, consumer electronics manufacturers unveiled thousands of new connected devices, including hundreds of tablets. ...
MS/MS systems are used in a variety of configurations. With the use of different ion sources, concerns may arise due to the “brightness” of the source. Because of this, it is imperative that the best collision cell be used for a given application. Read an empirical study of MS/MS systems to gain insight to improve configurations and ultimately your results.
