In a blender, whirl yogurt, lemon juice, apple juice and 1/2 cup of berries until smooth. Divide mixture among eight popsicle moulds. Slice remaining strawberries (leave raspberries whole) and divide them equally among the filled moulds, pushing each berry down inside mixture with a knife. Freeze pops overnight.
To remove frozen yogurt pops from the moulds, run warm water over sides of the moulds.
