Methods for controlled laser-induced growth of glass bumps on glass articles

A method for controlling formation of glass bumps in a glass article with laser-irradiation without the use of a growth-limiting structure. Standard deviation of height between the glass bumps on the article is less than 1 micron by controlling the laser radiation dose provided on the glass article.
