Abstract

A series of sequentially cascade pumped random lasers is reported. It consists of three random lasers, in which the Ag-Au bimetallic porous nanowires play the role of scatterers, and the gain materials are coumarin 440 (C440), coumarin 153 (C153) and rhodamine 6G (R6G) respectively. The random laser with C440 is firstly pumped by 355 nm pulsed laser. The emission of C440 pumps the C153 and the emission of C153 pumps the R6G sequentially. Low threshold coherent emissions from the three random lasers are observed. The cascade pumped random lasers can be achieved easily with low cost, and can be used in applications conveniently.
