Tunable Laser Light Sources Advance Nanophotonics Research
Sep 28, 2018 — A considerable part of contemporary photonics research that investigates the interaction of light with nanoscale objects — nanophotonics — is motivated by the commercial potential of real-world devices. A vast number of experimental studies call for high-quality, continuous-wave (CW) laser light that is tunable throughout the visible spectrum, but it is not straightforward to cover this region with most common tunable laser designs. Alternative sources based on CW optical
Laser-Machined Microresonators Offer Efficient SHG
SHANGHAI, Nov. 6, 2015 — Femtosecond laser micromachining and other processes can create smaller optical resonators out of lithium niobate (LN), potentially allowing their integration into chip-scale sensors. Whispering-gallery-mode (WGM) microresonators developed at the...
Nonlinear Microscopy Measures Effects of Laser Skin Surgery
FLORENCE, Italy, Nov. 19, 2014 — The effects of laser-based skin-tightening plastic surgery can be obvious to the naked eye, but harder to examine below the surface and at the microscale without a biopsy. A team from the University of Florence and other Italian institutions has...
Moving Raman Spectroscopy into the Clinic
Jun 9, 2014 — Raman spectroscopy’s molecular sensitivity makes it promising for clinical applications: It can identify pathogens much faster than current methods, investigate circulating tumor cells, help surgeons distinguish tumors from healthy tissue and...
Researchers Probe Graphene Alternatives with SHG
BERKELEY, Calif., May 7, 2014 — Scientists have a new way to study the optical and electric properties of 2-D metals that could compete with graphene in semiconductor and other applications. Using ultrafast IR pulses, researchers with the Lawrence Berkeley National Laboratory...
