A glass sheet is separated by propagating a crack in the glass sheet by moving a laser beam across the surface of the glass sheet along a desired line of separation and then streaming coolant at the glass sheet at a predetermined distance behind the laser beam. By altering the profile of a laser beam used to score glass, and by changing the distance between the spot where the laser beam impinges on the glass and the spot struck by the stream of coolant, the penetration depth of the resultant median crack can be controlled.

Title
