Hi Blue eyes;

One needs laser diodes for this purpose and they come in 635 to 685 nanometers 
which is in the IR zone. NEC manufacture on page
54 of Mouser cat.

I t might be possilbe to rig up a set of optics to focus the beam from a 
standard diode but it wont be simple.

So the hunt is still one for other color laser diodes.
