Send Morse Code Over Stockholm By Laser 139
bigmac writes "KTH, Royal Institute of technology is celebrating 175 year anniv by making a very spectacular laser show. A green laser sent from the bottom of an old reactor building 30 meters below ground. The beam is then reflected over the city from the schools clock tower.
And yes, you can send your own laser-morse messages through their homepage!" Here's an image to chew on.

I've seen green laser that were intense enough to been seen by the naked eye.. If you look at it from the correct angle with respect to the polarization, of course

Unless you're suggesting the laser is of sufficient power to ionize the surrounding air. I don't see that happening, either. Unfortunately, I can't find any details in a language I can read.
actually it doesn't need ionization or particles.. (Score:3, Informative)
the dipole oscillations are oriented with respect to the polarization of the light, so this light is most intense if you see it from an angle perpendicular to the polarization.
It's true that weak lasers has to reflect of particles, but I'm sure that this laser is powerful enough to cause dipole radiation... (maybe the reason why the didn't just move the laser from the basement it's placed in)

I remember when Pink Floyd [pinkfloyd.com] came here (Philly, USA) in '92 (or '91, I forget when The Division Bell [amazon.com] came out, I still have the shirt somewhere I think...), PHL [phl.org] had to redirect air traffic that night during the show because of the green lasers that they were using in the show. DAMN FANTASTIC SHOW, BTW, but the point is: yes, Green Lasers (especially) can be that visable and that vibrant.
Please look into things a bit before you post. Thank you.

Students at technical universities in Sweden generally own overalls in the colour of their student union section (a section usually roughly corresponds to one educational programme). These are worn at various parties. The students also design "patches" with their section or school logo, the "logo" of some big party or just a funny cartoon and sew these on their overalls.
When Bill Gates received his doctorate, the IT section at KTH started distributing a patch with a picture of Gates wearing a doctor's hat and with the text "You pay - you get".
It was immensely popular. I own two. =)

Five drunken sailors and a young attractive(at least she seamed so, at that time) girl, gave us five hours of fun morsetraining.

In a symbolic meeting between academia and the rest of the world, Stockholm's night sky will be adorned by a beam of light. A beam that has its origins in history, is part of our time and endeavours towards the future. A beam reflecting the advancements of technology and enterprise. A curious beam.
From a point 30 meters below the face of the earth, where once Sweden's first nuclear reactor was, a laser beam is produces and is reflected by the tower where pioneers once sent the first TV signals across Sweden. From here, the light is further projected over the city before reaching its goal: the City Hall.

Rockne Krebs and the Green Hypotenuse (1983) (Score:2)
The photograph [armoryarts.org] on a webpage describing the art looks remarkably like the Swedish project. From the webpage
Rockne Krebs was born in Kansas City, Missouri. In 1961 he received a B.F.A. in sculpture from the University of Kansas. Though not a painter, his fascination with ideas of color, along with his passion for sculpture, spawned a desire to create a sculptural work entirely made of light and color. Eventually this led to his development of "laser sculpture." In 1967 Krebs obtained his first simple HeNe (helium-neon) laser and created the piece Sculpture Minus Object. In 1969 he was sponsored by the Los Angeles County Museum of Art to work with Hewlett-Packard. They collaborated on a design for a piece that Krebs presented in the 1970 World's Fair in Osaka, Japan. This piece featured the first ever laser beam switching system and the prototype of the first laser light show. In 1983, Krebs connected the over 5,000-foot Mt. Wilson to the wall of Caltech's Beckman Auditorium over 7 miles away using light from a single argon laser. He allowed the laser beam to spread so by the time it reached the white exterior of the auditorium it was a constantly changing "painting" of green light. For The Universe: Contemporary Art and the Cosmos Krebs is creating a new piece using lasers and mirrors to connect the Armory building with the park across the street. He is also represented by two drawings, a medium he has explored in depth since the early 1970s.
