But of a nitpick but the lasers shouldn't have recoil because they are light beams
Even subatomic particles have mass (see Solar Sail), given that they have to bombard a spaceship of armoured mass (x)tonnes to destruction, I would suggest there would be recoil.
Edit: I guess it may be easier to counter the recoil force using the thrusters in a consistent protracted coherent beam than an explosion to propel munitions. Rail guns?! likely with a good on board computer easier to counter.
Anyhow, it is more likely to be effected by the condition and quality of the barrels/lenses/track and quality of counter thrusters and fuel combusted.
Yes I investigated myself to find that photons are considered without mass, I do not dispute this but would hypothesise some recoil with a vast amount directed in parallel solely upon one vector.
One proposed theory I have read regarding matter within the universe would be that all atoms at their most basic level are in fact waves trapped within a localised area, which if waves had absolutely zero mass, then multiples of these waves forming a structure would be zero as well.
