Does watching alot of blueray-movies wear out the laser of my Ps3 quicker?

I bought my Ps3 about a year ago mainly as a gaming-console but also to to serve as a way to watch blueray movies on my then brand new hd-tv. I have thought about a thing though, does watching alot of bluera movies wear out the laser on the console quicker and should i therefore be a little more cautios to how many i subjest it to. At the moment me and my fiance watch about 5 of em a month. Is this something i should worry about?

i use my ps3 almost solely as a blu ray player, its 3 years old, never had a single issue :) only time i play it is for uncharted ;)lewisg1212

Thanks for the info. I just wanted to ask since i thought about it alot, better safe then sorry you know.
