Can I get one treatment of Laser Hair Removal in order to thin out my coarse dark hair?

Male with course dark arm hair, I have very light skin so my hair really stands out. Can I do one treatment of laser hair removal in an effort to thin the arm hair and make some of the follicles less thick and noticeable. Will my hair grow back patchy? Specific laser light setting/or procedure that will do this effectively? I dont want to be left with patchy result and have to laser it all away, I think it would look worse than current situation. How many sessions/what strength level?
