That was addressed that in the next paragraph:

The optical energy does not have to be coherent however,
in order to trigger the gap.  Xenon strobes are typically
used in Back-Lit Thyratrons (BLT's) in order to initiate
an avalanche breakdown. Although BLT's are less expensive 
than LTG's, they're still out of the target price range 
for most coilers.
