Over seven years,scientists collected data from 250 million laser pulses.
The device on the drone releases laser pulses downwards at a frequency of hundreds of thousands of times per hour.
In the search for extraterrestrial intelligence,astronomers have hunted for radio signals and ultra-short laser pulses.
One that uses very sharp laser pulses and has a very fast detector can range an object to within a few millimeters.
The effect could also form the basis of a cheap andeasy way of characterizing ultrafast laser pulses- something that is currently very expensive to do.
First they stretched the laser pulses in time to reduce their peak power, then amplified them, and finally compressed them.
Your surgeon will subsequentlyrequest that you focus your eyes on a specific point so that laser pulses can be sent to the correct spot on your cornea.
In experiments, the scientists fired laser pulses onto a white cardboard floor just in front of a black cardboard corner.
Fotona's specially designed, innovative handpiece technology allows safe,precisely controlled and effective delivery of laser pulses to the treatment area.
The LDM302A uses invisible, eye-safe IR laser pulses to measure the distance to almost any natural surface in up to 300m distance.
Say you can get all the equipment in the image above,you still need to be able to translate voice commands into laser pulses so that control of smart speakers is possible.
Since the laser pulses in nanosecond but with super high energy, the shot pigment mass swell quickly and breaks into small pieces, which will be eliminated through metabolic system.
To get round this, the researchers first stretched the laser pulses in time to reduce their peak power, then amplified them and finally compressed them.
But now, scientists from Heriot-Watt University are claiming a breakthrough method that can weld together materials as different as glass and metal,thanks to ultrafast laser pulses.
The required intensity canonly be achieved by very short, powerful laser pulses- each plasma dot, or“flashpoint”, lasts for only about a nanosecond.
We encode the desired initial state of the system to be investigated in these qubits andimplement the operation sets by laser pulses," explains Christian Roos.
This is particularly important for clinical applications, as the laser pulses cannot penetrate the entire human body, hence the imaged region is normally only accessible from one direction.
The excimer laser uses an eye tracking system that follows the patient's eye position up to 4,000 times per second,redirecting laser pulses for precise placement within the treatment zone.
Sony uses a method called‘time of flight' that sends out invisible laser pulses and measures how long they take to bounce back, which he said creates more detailed 3D models and works at distances of five meters.
At the time, she said,many research groups were thinking about how to increase the power of laser pulses, but she and Dr. Mourou had a different idea.
Bouncing laser pulses off of this and other lunar reflectors could yield range data to the moon accurate enough to track millimeter-sized deviations in the Moon's orbit, effectively probing lunar composition and testing gravitational theories.
The second part of this year's prize-the invention of ultrashort and super-strong laser pulses- also once belonged to researchers' unrealised visions of the future.
Strickland, 59, and Mourou, 74,separately helped develop short and intense laser pulses that have"opened up new areas of research and led to broad industrial and medical applications.
The Honeycomb can see about 30 feet ahead on a flat surface, or double that when facing down a slope,and sends out laser pulses in a 360-degree horizontal field of view and a 95-degree vertical view.
After soaking the PDMS in phenylacetylene,the researchers used focused ultrafast laser pulses to induce an optical phenomenon known as multiphoton absorption in which multiple photons are absorbed at once.
The main technology Fisher hopes to use is aircraft-based Lidar,a scanning technique in which laser pulses are directed at the Earth's surface from an instrument attached to an aircraft.
