Frequency Comb to Probe Ultraviolet Wavelengths

Physicists at JILA have created the first "frequency comb" in the extreme ultraviolet band of the spectrum, high-energy light less than 100 nanometers (nm) in wavelength. Laser-generated frequency combs are the most accurate method available for precisely measuring frequencies, or colors, of light. moreAug. 01, 2011

Laser-Guided Atomic Force Microscopy

Application of Atomic Force Microscopy (AFM) to a broad range of research, and biological systems in particular, is hampered by two longstanding technical problems: mechanical drift and finding sparsely distributed samples. By adapting ideas from the optical-trapping community, we have made significant progress in addressing both of these issues, including a 100-fold improvement in the stability of AFM at ambient conditions. moreNov. 12, 2010

Nanoscale Microsocopy

The researchers characterize their new technique as a neat solution to the "needle in a haystack" problem of nanoscale microscopy, but it's more like the difference between finding the coffee table in a darkened room either by walking around until you fall over it, or using a flashlight. In a new paper, a group from JILA - a joint venture of the National Institute of Standards and Technology (NIST) and the University of Colorado - finds tiny assemblies of biomolecules for subsequent detailed imaging by combining precision laser optics with atomic force microscopy. moreFeb. 24, 2010

Open Doors to New Technologies

For nearly half a century, scientists have been trying to figure out how to build a cost-effective and reasonably sized X-ray laser that could, among other things, provide super high-resolution imaging. And for the past two decades, University of Colorado at Boulder (USA) physics professors Margaret Murnane and Henry Kapteyn have been inching closer to that goal. more
