Keep in mind that high power diode lasers probably won't be be single
mode, so the beam size can be large, several mm long. Thus they
won't focus to a point.
The fiber coupler is used to transform the long (several mm), narrow
(a few µm) laser output to a more useful circular shape.

The crucial thing is the fiber diameter and NA.
