This fractal pattern is actually a guide to shaping laser pulses. Each pixel in this image represents one possible laser pulse shape (the arrival time of the frequencies in a broadband laser pulse). The pixel’s color indicates how good that particular pulse shape should be at controlling a particular

Nano Street Fight Electron microscope image submitted by grad student Rajat Sharma of UCSD, who looked unsuccessfully with another grad student for a Brad Pitt-esque central character, before giving up and declaring the fight a total mess. They were testing the etching conditions for making a series of tiny uniform

Nanolasers with googly eyes! Because grad students. These are microscopic lasers, shown in various stages of completion. The innermost layer, looking like a slim grey column, is the semiconductor core, which actually does the light-amplifying. Next comes a layer of glass that coats the entire laser (the white puffy-looking laser)

A nano-lollipop? This is a tiny glass ball on a tiny stick made of polymer, a partially-completed nano-sized chemical sensor made by then-grad-student Matthew Chen. It’s on its way to becoming a nano-torch [http://lewisandquark.tumblr.com/post/92218390187/this-is-a-nanotorch-which-is-an-ultra-sensitive] , which can detect minute concentrations of chemicals due to

This is a nanotorch, which is an ultra-sensitive chemical detector, thanks to its ability to concentrate light. In the intense light fields at the torch’s top, a normally-weak light-based chemical fingerprinting technique (Raman spectroscopy) becomes millions of times stronger. More-sensitive Raman fingerprinting can allow us to detect trace contaminants
