Now as a Blaze Lasers rep I must mention that this guy is enquiring about a 2 watt IR laser from us and we have already refused his sale. We don't believe he is someone who should possess any laser let alone an enormously powerful 2 watt one that can melt stuff in an instant.
We would seriously rather lose a few dollars and keep the general public safe.
I never intended to purchase a 2W laser. I was only asking Spyro how IR lasers worked. How did you guys ever conclude that? I'm a DIY guy and I can't afford to spend a few hundred bucks on lasers.
Anyway back to the train issue, let me clarify that I didn't aim my laser at the train (vehicle) itself as what most of you seem to have concluded here. I way shining it around(in the dark) and the surface it hit happened to be a railway track. The train came and the driver saw the light on the track.
