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.
