Raman Amplification in Plasma Leads to Ultra-High-Gain Amplifier
Using a plasma medium, scientists have amplified short laser pulses of picojoule-level (pJ-level) energy up to 100 millijoules (mJ), a gain of more than eight orders of magnitude over existing capabilities. A large Raman backscattered energy of up to 170 mJ was measured for a monochromatic 70 joule (J) pump pulse incident at an angle of 175 degrees. Injected pJ seed pulses were observed to grow at a rate corresponding to a gain coefficient of 180 cm-1.

SERS-Based Sensor Detects Toxins at Ultralow Concentrations
A chemical sensor equipped with organic chemical compounds could provide selective, reproducible detection of miniscule amounts of heavy metal ions quickly. The sensor is based on a plasmon-polariton surface-enhanced Raman spectroscopy (SERS) platform.

Image Colorization System Uses AI to Direct Its Choices
A data-driven image colorization technique uses AI and deep learning to colorize images in real-time, providing even novices with the ability to quickly colorize gray scale images with satisfactory results. The system is guided by a Convolutional Neural Network (CNN), which propagates user edits by fusing low-level cues with high-level semantic information learned from large-scale data.

Photon Upconversion Technique Utilizes Plasmonics, Quantum Wells
A method to efficiently upconvert light combines plasmonic metals and semiconducting quantum wells to create a plasmon-powered device to boost wavelength frequency. The novel photon upconversion technique is mediated by hot carriers in plasmonic nanostructures.

New Polymer Material Goes for a Walk When Illuminated
A new polymer material has been developed that can undulate and propel itself forward when exposed to light. Scientists at Eindhoven University of Technology and Kent State University clamped a strip of the polymer material in a rectangular frame and illuminated it with one fixed light source; then they sat back and watched as it “walked” on its own.
