    Why is the blue laser affected very less cause of this but Red LASER is rapidly destroyed cause of this effect

    Possibly because both are at the extreme ends of the frequency spectrum of visible light.

    If that is the reason then the Blue Laser diode must also have some destructive effect why it is not having such an effect

    its because of bandwidth and the intensity variation.red laser is of more and sharp intensity with narrow bandwidth comparatively with others.

    The last table shows that almost all the colours have the almost same frequency Bw and blue has lesser BW than Red so it must undergo more destruction right

    ok it can be considered my pal,it won't looking in a matter of little value but which colour among all will have sharpness comparatively means red itself then comes blue .you can follow the below link to clear you r doubt jeffrey...
