In this paper, we study the generation of entanglement in a double-Lambda system. Employing a standard method of laser theory, we deduce the dynamic evolution equation of the two-mode field. We analyse the available entanglement criterion for the double-Lambda system and the condition of entanglement existence. Our results show that, under proper parameters, the two-mode field can be entangled and amplified.
