Thanks. Do the TO18 style cases have standardised pinout? The laser is
pressed into a block of aluminium, I don't want to risk trying to pry it
out, and even if I did - any type number would end up obliterated.

Now that, I couldn't tell you, I'm afraid. Actual pin numbers or type of
the device tend not to be shown on schematics. Sometimes, the optical
block is shown just as a block, with no indication of what's in it at all.
About the only thing that I can say is that there is usually a photodiode
in the package as well as the laser diode(s).

Must admit I didn't pay much attention as I tore the flexiprint off the side
of the sled and put the laser in a snuff tin for safe keeping - but I think
it only had 3 leads.

Assuming it has a PD; the 2 lasers would then have to be inverse parallel to
conserve pins?
