If I were to pulse those mini DVD lasers in sequence, assuming that they were all trained on the same target, could I produce temps high enough to be a decent laser cutter? Or do lasers just not work that way.
I think that If I train 40 of those lasers and run them at 1 watt for 1/40th of a second each, I should be able to produce a significant result.

DVD laser diodes have been used to build laser cutters / laser engravers, as a google search will quickly show.
They aren't fast, but they work.
Blu-ray lasers work much better, though.
Just a single laser from a DVD burner or Blu-Ray writer, in all those examples.
