Blu-ray Laser Bursts 100 Black Balloons |
 Got an old Blu-ray player from which you can cannibalize the laser unit? Scott Stevenson did, and use used it produce this video. Blu-ray players use a 405 nm (more violet than blue - see thumbnail) laser diode that emits a 580 nm beam at around 5 mW. I'm guessing black balloons are used because they absorb more of the light energy and therefore heat faster. A debate on the YouTube page argues between melting or air heating causing the balloon to burst. My money is on local melting since it would take a long time to heat the air inside enough to expand enough to cause the popping. Posted May 2013 |

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
