I think if its range were increased it could be used as a last resort suicide/super weapon at the cost of massive power requirements.
Example being if a Titan or capital ship were surrounded and about to fall, one could trigger this damage pulse wiping out or disabling ships that are within range, but would require a massive amount of power and possibly harm the ship using it. I think combined with an ion effect the disable part could become devastating to a fleets operations.
Another idea would be for an 'electronic warfare' useage on smaller craft using the same principal but to a less deadly effect.
