Since its a high energy beam lets have it also push folks around and off of platforms.
I.e. heavy uses laser and pushes scout out of cover. Scout uses laser versus heavy and scout is pushed back unless kneeling.
Scout aims laser at ground and is pushed up in the air as an improvised jetpack.
Laser is used IRL to slow down atoms traveling thousands of miles per hour to a much slower speed of inches per minute. |

What a ridiculous idea. Plasma and metal should realistically push someone much more than a laser would. |

But photons do have MOMENTUM. The amount of MOMENTUM is only limited by available power from the laser source.
If we can right now use lasers to slow down atoms from speeds of thousands of miles per hour to inches per hour than what about technology 30, 000 years into the future??

Still doesn't change the fact. Solid matter has more momentum than photons, much more, therefore other weapons should have more push and lasers should have almost none. |

Ion drive works similarly to what you want, but only in space, where opposing forces are almost non-existent. The Solar Sail concept is based off of using Photon momentum to perpetuate spacecraft, but they need Very very large surface area and minimal mass, and lack of opposing forces. On a planet, no such momentum could be achieved without substantial, and I mean substantial amounts of energy. |

Thats the point that the game is set 30, 000 years in the future.
What needs 80 megajoules to launch a tiny metal spacecraft hundreds of meteres into the air can be a portable power pack in the future.
And speaking of portable laser energy weapons the DOD is makeing strides to getting those ready for combat.
This conversation on portable laser power limits reminds me of a conversation back in 1983 about computers never being able to have the memory RAM to play a single five minute song.
Boy those naysayers were right huh? Excuse me while I listen to some tunes on my Ipod Nano. |

Notice how this extremely high-powered laser (about the same as an Amarr Laser Rifle) does not push its target.
While it is true that the extremely tiny virtual mass of photons travelling en masse at the speed of light exerts a small, but measureable amount of force, the amount of light necessary to move significant mass is mind-boggling. The lasers that NASA talks about using to move spacecraft are either: a) stadium-sized; or, b) moving things in microgravity with a very long travel time.
Furthermore, if the Laser Rifle pushed with enough force to move a dropclone- it would be pushing in both directions, i.e.- the LR would have "kick". Even if the user wore a Heavy dropsuit, the device itself would be wholly unwieldy. Instead of pulses of kick, the LR would drive backwards and up constantly.
If you have ever seen someone holding a fire hose- yeah it would look like that.

Momentum of photons is determined by the wavelength/frequency, not by intensity. http://en.wikipedia.org/wiki/Momentum_of_photon#Physical_properties
We'd have to be using Gamma Ray Lasers. And as Ulysses said, momentum of Blasters would be much greater than laser beans. |

Nothing moving via laser in normal Earth gravity?? Hmmmm.

Wait, all that does is support Ulysses, that thing operates via plasma, inducted by laser, not by lasers itself...
EDIT: Thanks for these links, they're fairly interesting. |

I am well aware of the Lightcraft and similar projects. I've spoken, in person, with individuals involved in similar research.
Note that the laser used to lift that small, soup-bowl-sized piece of lightweight aluminum was designed for shooting down missiles at extremely high altitude. I was not joking when I said that the lasers NASA was talking about for lifting spacecraft would be stadium-sized. The target area for the beam (burning square) was almost as large as the craft. The aperture of the laser was two or three times as big as the craft.
It is furthermore worth noting that it was not the laser that actually pushed, but rather the focused discharge of plasma created by superheating the air underneath the craft's bell.
In order to do that to a dropsuit, you would need to do two things:
1) Change the Laser Rifle's discharge pattern so that it struck an area about 1.5m in diameter. 2) Fit the dropsuits with a special bell-and-cone shaped plasma sail about 3m in diameter. |

I do not think you can comprehend how effective the laser push is. SOLAR SAIL: A solar sail, simply put, is a spacecraft propelled by sunlight. Whereas a conventional rocket is propelled by the thrust produced by its internal engine burn, a solar sail is pushed forward simply by light from the Sun. This is possible because light is made up of packets of energy known as GÇ£photons,GÇ¥ that act like atomic particles, but with more energy. When a beam of light is pointed at a bright mirror-like surface, its photons reflect right back, just like a ball bouncing off a wall. In the process the photons transmit their momentum to the surface twice GÇô once by the initial impact, and again by reflecting back from it. Ever so slightly, propelled by a steady stream of reflecting photons, the bright surface is pushed forward.
A solar sail is made up of just such a reflective surface, or several surfaces, depending on the sailGÇÖs design. When the bright sails face the Sun directly, they are subjected to a steady barrage of photons that reflect off the shiny surfaces and impel the spacecraft forward, away from the Sun. By changing the angle of the sail relative the Sun it is possible to affect the direction in which the sail is propelled GÇô just as a sailboat changes the angle of its sails to affect its course. It is even possible to direct the spacecraft towards the Sun, rather than away from it, by using the photonGÇÖs pressure on the sails to slow down the spacecraftGÇÖs speed and bring its orbit closer to the Sun.
A typical spacecraft going to Mars, for example, will be displaced by more than 1,000-ákm by solar pressure, so the effects must be accounted for in trajectory planning, which has been done since the time of the earliest interplanetary spacecraft of the 1960s.

Solar Sail Um, thanks for the recap on a solar sail, but the little spacecraft that the OP brought out to show, operates by super heating air into an explosive plasma state. OP is not talking about solar sails... |
