    Lasers used to power helicopter flight

    I thought that people here might find the following article interesting. A small helicopter was powered by laser pointers. Ascending Technologies and LaserMotive create a new record. | sUAS News I wonder if it wouldn't be too difficult to pull this off at home. They seem to set a flight...

    Using Hoya R-72 IR transmission filter to measure IR from DPSS lasers [videos]

    Introduction Cleaning house a few weeks ago I ran across my Hoya R-72 infrared transmission filter. These filters are used for infrared photography. They are designed to block all visible light below long red wavelengths of approximately 720 nM. As such they are perfect for measuring infrared...

    Lasers used to trap single atom.

    "The three-year project used laser cooling technology to slow a group of atoms, before a laser beam, or "optical tweezers", isolated and held one atom." Kiwi scientists make atomic 'breakthrough' | Stuff.co.nz

    Article on advance in laser tractor beams

    "Andrei Rhode, a researcher involved with the project, said that existing optical tweezers are able to move particles the size of a bacterium a few millimeters in a liquid. Their new technique can move objects one hundred times that size over a distance of a meter or more." Tractor beams come...

    Optotronics vs. Novalasers: Shootout in the $200 green corral

    Edit: The Optotronics unit in this review is apparently defective, possibly from shipping. This review will be updated when a new unit arrives. This is a detailed one-on-one comparison of the Optotronics Premium +150mW Green Laser against the Novalasers X100 Compact Portable Laser. Both of...
