Who, now, is Ophelia’s dove? I mean – it makes sense that she might speak this directly to Laertes – I’ve seen it done that way often.
But – a dove is something that files away – so either Hamlet or Polonius might be better candidates. The rhyme of dove and love would suggest Hamlet to me – but then again – she has just been singing a funeral song – so that makes Polonius a more likely dove.
I think it would be weird to call your father your dove, though. But maybe that’s just me.
