[QUOTE="Deset Gled, post: 9229945, member: 7808"] True, light (of the right wavelength) goes through water. But we're not talking about just water, we're talking about the ocean. It's a completely non-homogeneous mixture of dissolved organic matter, debris from anything from salt to stone to plastic, and all sorts of living stuff. Net absorption of anything in the visible spectrum is going be well over 50% before 100m, which means more of your energy is going to be lost to the ocean than your target. Hence, you heat the water before you do any real damage at range. As for coherence, well, the coherence of your beam is affected quite a bit if there's no coherence in your media. [/QUOTE]
