Apparatus (

20

) and a method for laser scribing a coated substrate (

22

) utilizes a rotating polygonal mirror (

36

) to split a pulsed laser beam (

30

) in order to provide spaced ablations (

34

) in a coating (

26

) on the substrate. The laser pulses are directed through at least one lens (

56, 60

) and may be passed through fiber optics (

62

). A laser detector (

68

) may be used to detect the rotational position of the rotating polygonal mirror (

36

). A controller (

76″, 76

′″) allows a second set of scribes to be generated with reference to the first set of scribes.
