Laser sailing is popular because it is a one handed, one design dinghy class that prioritizes athleticism and skill over improvements in boat performance. A laser beam's light waves are coherent, meaning that the photons are moving at the same wave length and in the same direction. This is accomplished by passing the charged electron through an optical gain medium, which could be a solid like glass or a gas.

The particular wavelength of light is determined by the energy generated as the excited electron descends to a lower orbit. The energy levels injected can be changed based on the material in the gain medium to obtain the appropriate beam hue.

A mirror on one side of the laser's optical material reflects the photon back toward the electrons in laser sail for sale. The "cavity," or space between mirrors, is made to allow the photon to be recycled back into the medium, so encouraging the emission of a virtually exact clone of the required photon for the particular type of optical gain medium. They both go in the same direction and at the same speed to bounce off a second mirror on the other side, repeating the cloning process.

Two becomes four, four becomes eight, and so on, until the photons are amplified enough to move through the mirrors and the optical material in perfect synchronicity. Think of them like members of a coordinated marching band at the Rose Parade. And that unity is what gives the laser its power. Laser beams are capable of sustaining their high intensity across long distances, even to the moon and back.

Why choose us

Some lasers, like ruby lasers, emit brief flashes of light and others, like helium-neon gas lasers or liquid dye lasers, emit light continually. NIF generates light pulses that are just billionths of a second long, just like the ruby laser. The laser light does not have to be visible. The beams travel as invisible infrared light initially, then through specialized optics that change it into visible green light and then invisible, high-energy ultraviolet light for optimal interaction with the target.
