Freeze-Ray lets you freeze stuff with just lasers

Instead of motors and fans, fridges and other active or passive cooling systems we might one day be able to use just a laser beam.

Theories from back in 1995 stated various strategies to freeze stuff with laser but those were only demonstrated on single nano-crystals provided in vacuum, recent developments in technology combined the brilliant minds of the era researchers have developed a demonstration of refrigeration by laser.

Yes with the smirking faces of supervillains scientists have developed the Freeze Ray.

A team of scientists from the University of Washington are successful in Freezing down a liquid by a laser! Now that is something really “cool”.

This significant ultimate breakthrough was accomplished by the team with the bombardment of a infra-red laser on a liquid cooling I down to 20°C (36°F), making it a first time in the scientific history to cool something with a laser else lasers were used for heating up stuff until now but no more the era of refrigeration with lasers has begun.

How does it work?

Well for starters to understand in this technology the laser is not directly bombarded on the liquid it is made to pass through a special microscopic crystal, the crystal disintegrates the infra-red light in to visible spectrum with reddish green seeming light, which is more energetic than the lasers original infra-red light.

To get this shift in energy from infra-red to visible light the nanocrystals need to get or we can say absorb energy from somewhere, this energy is sucked from the fluid surrounding the crystal and hence cooling the liquid.

A breakthrough in science!

The idea of cooling stuff with a laser has the roots for the ideas in scientist’s minds regarding researches about the regeneration and explicit working of cells and tissues and all other microscopic sciences yet to unveil by humans.

By freezing just a part of tissue culture scientist can examine the development and regenerative cycles going on in the cells as these would take place slowly in partial cooled state, also if the experiment results in damage of the tissue it would have comparatively no effect on the tissue culture as the part froze by the laser would be too small.

Thus the ability to reduce temperature in a stable and controlled manner has helped scientists slow down the chemical and biological processes and examine these processes closely as to how these happen.

What do the Brilliant minds say ?

 

“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,”

“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 behaviour.”-Peter Pauzauskie.

“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,” Paden Roder, lead author of the study, commented . “We are interested in the ideas other scientists or businesses might have for how this might impact their basic research or bottom line.”

Well for all that’s worth introducing a laser technology fr refrigeration purposes is going to prove a  major shoreward to the home science and help open up the secrete doors of the theories behind regeneration and a lot more.
