How did we calculate the distance between the Earth and the Moon? Apollo 11 had lasers to thank for that! #FunFact

"Microscale lasers are widely used in devices such as CD and DVD players. Now, optical engineers are developing nanoscale lasers—so small that they cannot be seen by the human eye.

A tiny laser comprising an array of nanoscale semiconductor cylinders has been made by an all-A*STAR team. This is the first time that lasing has been achieved in non-metallic nanostructures, and it promises to lead to miniature lasers usable in a wide range of optoelectronic devices."

You may measure your strength in the gym by how much you can lift, but did you know that the strength of early lasers were measured in gillettes? #FunFact

Lasers don't just have the ability to be versatile, powerful and colourful, but they can be extremely accurate too. Did you know that they can measure accurate to more than a #nanometer? #FunFact

With NASA's ICESat-2 launching earlier today, there's even more news on laser applications in space!

"In the coming months, researchers at NASA’s Jet Propulsion Laboratory expect to take a series of small steps that will ultimately result in a giant leap in laser-enabled Mars telecommunication capabilities. Their technological progress will contribute to a telecommunications infrastructure around the planet that will support both human and robotic expeditions.

"DSOC’s laser communications are considered emerging technology that promises some major advantages over traditional radio-frequency communications. 'The main benefit is that the laser beams are much narrower than your radio-frequency beams, so you can get more energy density at the target. The amount of information that you can transmit for a second, the megabits per second, goes up the more power density you have at the receiver. You get a big boost in data rates.'"

Ever wondered how your laser pointer comes out in that lovely luminous green colour? You can thank infrared and frequency doublers for that! #FunFact

This weekend, NASA is planning to launch a spacecraft that will use half a dozen bright-green laser beams to measure seasonal and annual changes to Earth's icy poles. The mission, called the Ice, Cloud and land Elevation Satellite-2 (ICESat-2), will take incredibly precise measurements of ice sheet depth.

The spacecraft is scheduled to take off from Vandenberg Air Force Base in California on Saturday, Sept. 15, during a launch window that will open at 5:46 a.m. local time (8:46 a.m. EDT, 1246 GMT) and last for 2 hours and 34 minutes.
