Since the first laser was invented in 1960, they've almost always given off heat -- either as a useful tool, a byproduct, or a fictional way to vanquish intergalactic enemies.
But those concentrated beams of light have never been able to cool liquids. University of Washington researchers are the first to solve a decades-old puzzle -- figuring out how to make a laser refrigerate water and other liquids under real-world conditions.

In a study to be published the week of Nov. 16 in the Proceedings of the National Academy of Sciences, the team used an infrared laser to cool water by about 36 deg F -- a major breakthrough in the field.
"Typically, when you go to the movies and see Star Wars laser blasters, they heat things up. This is the first example of a laser beam that will refrigerate liquids like water under everyday conditions," said senior author Peter Pauzauskie, UW assistant professor of materials science and engineering. "It was really an open question as to whether this could be done because normally water warms when illuminated."
The discovery could help industrial users "point cool" tiny areas with a focused point of light. Microprocessors, for instance, might someday use a laser beam to cool specific components in computer chips to prevent overheating and enable more efficient information processing.
Scientists could also use a laser beam to precisely cool a portion of a cell as it divides or repairs itself, essentially slowing these rapid processes down and giving researchers the opportunity to see how they work. Or they could cool a single neuron in a network -- essentially silencing without damaging it -- to see how its neighbors bypass it and rewire themselves.
"There's a lot of interest in how cells divide and how molecules and enzymes function, and it's never been possible before to refrigerate them to study their properties," said Pauzauskie, who is also a scientist at the U.S. Department of Energy's Pacific Northwest National Laboratory in Richland, WA. "Using laser cooling, it may be possible to prepare slow-motion movies of life in action. And the advantage is that you don't have to cool the entire cell, which could kill it or change its behavior."
The UW team chose infrared light for its cooling laser with biological applications in mind, as visible light could give cells a damaging "sunburn." They demonstrated that the laser could refrigerate saline solution and cell culture media that are commonly used in genetic and molecular research.
To achieve the breakthrough, the UW team used a material commonly found in commercial lasers, but they essentially ran the laser phenomenon in reverse. They illuminated a single microscopic crystal suspended in water with infrared laser light to excite a unique kind of glow that has slightly more energy than that amount of light absorbed.
This higher-energy glow carries heat away from both the crystal and the water surrounding it. The laser refrigeration process was first demonstrated in vacuum conditions at Los Alamos National Laboratory in 1995, but it has taken nearly 20 years to demonstrate this process in liquids.

As they are cooled by the laser, the nanocrystals developed by the UW team emit a reddish-green "glow" that can be seen by the naked eye. [Dennis Wise/University of Washington]
Typically, growing laser crystals is an expensive process that requires lots of time and can cost thousands of dollars to produce just a single gram of material. The UW team demonstrated that a low-cost hydrothermal process can be used to manufacture a well-known laser crystal for laser refrigeration applications in a faster, inexpensive, and scalable way.
The UW team also designed an instrument that uses a laser trap -- akin to a microscopic tractor beam -- to "hold" a single nanocrystal surrounded by liquid in a chamber and illuminate it with the laser. To determine whether the liquid is cooling, the instrument also projects the particle's "shadow" in a way that allows the researchers to observe minute changes in its motion.
As the surrounding liquid cools, the trapped particle slows down, allowing the team to clearly observe the refrigerating effect. They also designed the crystal to change from a bluish-green to a reddish-green color as it cools, like a built-in color thermometer.
"The real challenge of the project was building an instrument and devising a method capable of determining the temperature of these nanocrystals using signatures of the same light that was used to trap them," said lead author Paden Roder, who recently received his doctorate from the UW in materials science and engineering and now works at Intel Corp.
So far, the UW team has only demonstrated the cooling effect with a single nanocrystal, as exciting multiple crystals would require more laser power. The laser refrigeration process is currently quite energy intensive, Pauzauskie said, and future steps include looking for ways to improve its efficiency.
One day the cooling technology itself might be used to enable higher-power lasers for manufacturing, telecommunications, or defense applications, as higher-powered lasers tend to overheat and melt down.
"Few people have thought about how they could use this technology to solve problems because using lasers to refrigerate liquids hasn't been possible before," he said. "We are interested in the ideas other scientists or businesses might have for how this might impact their basic research or bottom line."
The research was funded by the Air Force Office of Scientific Research and the UW, and benefitted from additional support from the National Science Foundation, Lawrence Livermore National Laboratory, and Pacific Northwest National Laboratory.
Co-authors include UW doctoral students Bennett E. Smith in chemistry, Xuezhe Zhou in materials science and engineering, and Matthew Crane in chemical engineering.
