It is shown that there is a general relation between optical saturation intensity and tunnel bandwidth. The physical mechanism of this relation is analyzed. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=3D2F0C94CF4F93B096FA918518AB9412&yid=D418FDC97F7C2EBA&vid=ECE8E54D6034F642&iid=DF92D298D3FF1E6E&sid=CD794621A184DC14&eid=E062BF8B95A95FD2&journal_id=1000-3290&journal_name=物理学报&referenced_num=0&reference_num=0
