Walkthrough
Method 1
One way to get this achievement is to grab the Spartan Laser on Snowbound under the first base, head towards the back of the cavern which is the main "Arena" that everyone usually flocks to and make sure only the muzzle is sticking out of the energy door shield. Since more than likely all the players will be here and usually only take the tunnel entrances, they'll be too busy fighting each other to notice you charging up your laser from the posterior of the cavern.
Method 2
Another way to get this achievement is to also use the Spartan Laser on King of the Hill gametypes, where everyone will be grouped inside the hill and not able to pay attention to a Laser charging up in the background.
Method 3
One more way is plain and simple and is to have the Spartan Laser on maps that contain Ghosts, and all you would need to do is charge the laser and get the right moment for when someone boards the Ghost, using the Laser to destroy the Ghost will result in the driver and the boarder being "Lasered".
Method 4
And of course another way is, to ask somebody to help you with the achievement during a match. Simple (then again, potential interference from the players who are not there to help you can still make it not so simple)!
Luck!
Sometimes, this achievement is scored by randomized luck and fortune when you try to kill one person and another comes in the way of the other for a close-combat duel. Of course, this is dependent on nothing, but a straight-shot from the Spartan Laser and a great deal of luck. There are also many players in the Legendary Brawl playlist that help each other get this achievement.
