[Leroy S. Mort]

The word is slang to begin with, so neither spelling is 'correct'

Not to pick nits, but "lase" certainly is a word. It's in the dictionary.

lase
intr.v. lased, las·ing, las·es

To function as a laser; emit coherent radiation by the action of a laser.

Ahh, well, looks like it made it into the English language! My dictionary is 1994, so it must be a recent addition. Thanks for the info.
