Yes there is a way to do that with lasers, and Dair. When holding onto the ledge, pull away from the stage by pressing the control stick away from the stage. When you have pulled away you'll start falling, once you reach a certain distance, move falco with the control stick towards the stage and use your second jump. This creates your forward momentum to get back onstage. After you have started your 2nd jump, input the command for the Dair or laser.
But in order to land on the stage laglessly with Dair or lasers, you have to time yourself correctly. Learning that timing comes from just practicing.
