I was planning to use one that I believe comes from a Blu-ray device.
 I believe that the one used for recording in early CDR's was IR, but
I don't know so much about more recent DVD, Dual layer, and high
density recording devices.  

What I ordered is supposed to be a 405 nm laser diode - not quite what
I consider UV, but close, and in a range that is at least somewhat
effective for many photoresist materials.
