Bellafill is normally injected relatively deeply and laser treatments usually only affect the surface of the skin. I would recommend waiting about 2 weeks after Bellafill before having a laser treatment, just to allow any swelling to dissipate and to allow the Bellafill to settle in.
There is no waiting time to have a laser or RFM after Bellafill. The filler will be unaffected and studies prove that. In fact, you don't have to wait after any filler to get these treatments. The Restylane fillers are heated to 120C for 20 minutes to sterilize them so temps or 65-100 for millisecs won't affect them whatsoever.
