The present invention is a solid rinse aid composition and methods of making and using the same. More particularly, the invention relates to carbamate-functional addition polymers having at least 250 grams of polymer per carbamate group which are made with less than 35 percent by weight of nonfunctional monomers, preferably with less than 20 percent by weight and most preferably from 0 to less than 10 percent by weight, based on the total weight of the polymer. The method begins by applying a bias level to a laser diode in the uncooled laser package that optimizes distortion and causes the laser package to generate the second optical power level. The cantilever may be silicon or silicon nitride.
