Laser marking Nickel /Chrome plated steel with Sulfur in Nickel coating

What happens to the Sulfur in high content Sulfur Nickel-plating when using a laser to mark bar code info on a Nickel / Chrome plated steel product, (Chrome removed in the lasered area but heat effected Nickel remains). Does the Sulfur react the same way it would in arc welding a high Sulfur content steel by making micro explosions. If it does would this cause micro cavities in the Nickel, which would expose the base metal.

Thank you finishing.com for the letter forum.
