In this work, an organic composite polymer random laser (RL) operating underwater has been studied. The RL structure used in the test is a rod-shaped composite, formed by a mixture of an organic green light-emitting polymer and a UV transparent polymer matrix. RL action was sustained by both the multiple scattering and whispering-gallery-mode effect. The demonstration of RL action and the test of its operation lifetime in such an organic composite RL operating in water suggest the feasibility of its promising future applications in areas of underwater optical communications and/or remote optical sensing.
