This seemed like a good day to post some rainbow laser modes! Light in a circular cavity makes a variety of standing wave patterns, some of which look like flowers, wagon wheels, or even tie-fighter spaceships. These images are from my simulations of the light in the cavities of nanolasers

This is the nanolaser equivalent of being smacked in the face with a slab of corrugated roofing during a tornado.  There’s one step in making microscopic lasers where you have to peel away metal from much of the substrate, leaving behind pillar-shaped lasers surrounded by small metallic patches.  These

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

Like a tiny shiny mountain, this nanolaser and the area around it is coated in a layer of blobby silver.  The silver serves as a mirror that keeps the laser light bouncing around inside the laser’s light-amplifying interior, generating more and more copies of itself.  A tiny percentage of

A Devil’s Tower-like monument rises above a sea of bubbles.  It’s just another day in the life of a nanolaser researcher. The tower is a microscopic laser in the process of being built - here, it’s shown after it was carved out of a flat sheet of

The one on the left is a nanolaser, carved by high-energy plasma and strong acid, and invisible to the naked eye.  The one on the right is a hoodoo, carved by wind and rain, and is approximately 20 million times larger. And about 60 million times older. The reason they

It resembles a mushroom cloud, but in fact, it’s one of our microscopic nanolasers, imaged under an electron microscope.  These lasers are among the smallest in the world, so small you could fit a billion of them on an iPhone home button, small enough to one day fit easily

The view inside one of our lab’s titanium sapphire infrared lasers - if you see a view like this, you’re doing something wrong.  Specifically, you’re not wearing laser goggles around a 10W laser source (bad), and placing your eyeballs at beam height (very bad, yet done almost

Here’s the jagged edge where my sample broke. I blame the carbon tape, which is usually my friend, a nice way to get rid of those pesky extra electrons, and a way to stop my sample from falling off the holder in the electron microscope.  Except this time, the
