…but in reality has degraded properties (higher divergence and lower radiance). Often the quality of a laser beam is
specified using the M2 (M squared) parameter. For example, a YAG laser operating exclusively in the TEM00
mode has M2 = 1, while multimode laser diodes
have an M2 of…

…number of vias per area increases with the
square of the pitch, the number of through vias which fit
into the field will increase likewise. Hence, the parallel
drilling rate (holes per second) actually increases with the
square of the pitch size. In contrast, in the case of…
