We find that the critical slowing down at the edges of bistable region possesses consistency with the divergence of the time duration of intermittency. The critica1 exponent is 1/2. We also find that, different from the critical points at the bistable region edges, there are consistencies with the period-doubling bifurcation points and split bifurcation points at the cusp point (in cusp catastrophe model of bistability). The critical exponent is 1. The abo-ve-mentioned results possess universal properties. The computer experiments have been made in the liquid crystal hybrid optical bistable device. The results are in agreement with the analyses. %U http://www.alljournals.cn/get_abstract_url.aspx?pcid=6E709DC38FA1D09A4B578DD0906875B5B44D4D294832BB8E&cid=47EA7CFDDEBB28E0&jid=29DF2CB55EF687E7EFA80DFD4B978260&aid=9D1D82324E265FFE451BCB81381DAB07&yid=74E41645C164CD61&vid=339D79302DF62549&iid=F3090AE9B60B7ED1&sid=603BC00D7DC5FEAC&eid=4B24DA4DB6EBAD78&journal_id=1000-3290&journal_name=物理学报&referenced_num=4&reference_num=0
