Temporary Hair Removal With Laser or IPL

Is there any type of laser or IPL that basically just instantly eliminates your hair temporarily after one treatment, unlike laser which takes 3 weeks or so to fall out? Basically I am just looking for a way less painful way than waxing to remove hair for a 2 week vacation and shaving, tweezing, or waxing, etc is not what I am interested in since I get horrible ingrowns.
