    "abstract": "Two remote parties, Alice and Bob initially share some non-maximally\nentangled states. Through the entanglement concentration by local operation and\nclassical communication(LOCC), they may obtain an outcome of maximally\nentangled states in the price of decreasing the number of pairs shared by them.\nRecently, entanglement concentration have been experimently demonstrated by\npost-selection (T. Yamamoto et al, Nature, 421, 343(2003) and Z. Zhao et al,\nquant-ph/0301118). Here we give a modified scheme which can be used for the\nentanglement concentration without any post selection by using only practically\nexisting linear optical devices. In particular, a sophisticated photon detector\nto distinguish one photon or two photons is not required. Our scheme can be\nused to really produce the event-ready maximally entangled pairs through LOCC\nprovided that the requested raw pairs are supplied deterministically. A\ndetailed experimental plan with spontaneous parametric down conversion(SPDC) is\nshown.",
