here is my Solution for this Achievement.
The Lasers are between the 105/106. and 154. Floor, its impossible to miss.
If you hit a Laser, restart the Checkpoint and all is clear. This have no effects for your Achievement.
Without hitting the Laser is really easy, the only thing what i do is, jump at the right Moment and a "Air push" with LT+A
Between the 2 Laserbarrage is a little Fight.
