Subwavelength EUV Imaging

December 1, 2017|OSA - Optics 2017|

Tabletop coherent EUV/SXR beams are now possible using high-harmonic generation (HHG).1,2 In addition, a new generation of powerful coherent-diff ractiveimaging (CDI) techniques is removing the resolution limits imposed by traditional X-ray microscopy, by replacing lossy and imperfect X-ray optics with powerful iterative phase retrieval algorithms.

Symposium X—Frontiers of Materials Research

November 28, 2017|Materials Research Society|

In her Symposium X talk on Monday, Margaret Murnane of the University of Colorado Boulder described methods to create coherent sources with extremely short wavelengths, with excellent spectral, temporal, and polarization control. “Thirty years ago,” she said, “we never thought that we could achieve the same kind of control—and perhaps better control—over light in extreme UV and soft x-ray region as we could in the visible region of the spectrum.”

STROBE Imaging: How STROBE is modeling the future of research

November 8, 2017|University of Colorado Boulder|

From life-saving advances in medicine to life-changing opportunities in renewable energy, imaging technology offers a window into worlds that can’t otherwise be seen by the human eye. That makes it an essential tool across a broad range of scientific disciplines, from engineering to biosciences. But despite their widespread use, today’s imaging techniques remain limited. Finding a solution to this problem will require collaborating with other institutions and developing new ways to educate up and-coming scientists. Based at CU Boulder, the Science and Technology Center on Real-Time Functional Imaging—known as STROBE—is designed to do exactly that.

Tracking long-range energy flow on its native nanometer and picosecond scales

October 30, 2017|Berkeley College of Chemistry Press Release|

In a new study, appearing in the November 2017 issue of Nature Materials, a research team led by UC Berkeley Associate Professor of Chemistry and Physics, Naomi S. Ginsberg, has announced the development and implementation of the most direct method to-date to track the nanoscale process of energy flow that punctuates the initial picoseconds after light absorption in some natural and artificial light harvesting systems. The research results are also available online at the Nature Materials website.

Manipulating nature with X-ray lasers is topic of Oct. 18 lecture

October 2, 2017|Cornell Chronicle|

Ever since the invention of the laser more than 50 years ago, scientists have been striving to create an X-ray version. But until recently, very high power levels were needed to make an X-ray laser. Making a practical, tabletop-scale X-ray laser source required taking a new approach, as will be described by physicist Margaret Murnane in this fall’s Hans Bethe Lecture.

Farther Than the Eye Can See

May 30, 2017|The Institute for Digital Research and Education|

The physical lens had been the standard for use in the detailed study of microscopic organisms since Hooke’s seminal work Micrographia was published in 1665. Dr. Jianwei Miao, a professor of Physics and Astronomy and the California NanoSystems Institute at UCLA, blew that standard out of the water with a method known as Coherent Diffractive Imaging (CDI).
