What does that mean and how is it demonstrated by manga
Power of a laser can be increase by increasing the intensity of the light. By intensity I mean number of photons/area.
It isn't verbatim demonstrated. I am just saying a way that light attacks can be made stronger.
DPS (Damage per sec) is not increasing the strength of light. You are just dishing out more attacks to stack damage.
Higher frequency waves have more power than lower ones.
Eg, UV light has more energy than visible light, for same intensity.
There was never a mentioned on OnePiece to tiers of light damage so I have no reason to hold pacifista having weaker light attacks. In fact we have actual scans of these attacks being stated replica from Kizaru.
As well as favorable cool-time deduction (DPS)
Sure, but I think it's implicitly understood.
We know some fire is stronger than other fire - more intense/thick fire is stronger, hotter fire is stronger. This is present in manga too, with the highest attack power fire (i.e hotter and thicker/more intense fire) so far being compared to magma (the ones Kaido and King used).
Same should apply to light, based on the factors I mentioned above - via frequency and intensity.
Not to mention, even for same intensity and frequency, you can still dish out more attack power by increasing the area of the beam.
Just because pacifista have lasers based on Kizaru, doesn't mean they can dish out with the same factors that Kizaru can dish out.
We even see varying attack power of lasers:
- Queen tanked his own laser inside his mouth, tanked his own lasers fired on his back, without much damage
- base Kaku tanked a bunch of Vegapunk lasers (which are also based on Kizaru's) without much damage
Imagine if those were lasers from serious Kizaru. You think Queen and Kaku are just walking off easily tanking lasers from a serious Kizaru?
This hypothetical serves to show that lasers can have different attack power
