Different diodes have different divergences, usually astigmatic, so the
optics have to be customized for the diode. If you had an exact replacement
for the defunct diode you could replace it, but the laser would still have
to be realigned internally. Basically the cost of the laser is wrapped up
in the man-hours to align it and the like, so you probably wouldn't save
much money trying to do this. Finally, most of the cost of a 405 laser *is*
the cost of the diode. They go for anywhere from $300 to $1500 dollars
depending on the output power.
