Abstract
In this paper, we report on the fabrication of mechanical controllable, sticky and flexible random lasers based on double-sided tapes that are cheap and commonly available. A double-sided tape is used as the scattering medium. Two different solutions of rhodamine B dye doped with ethylene glycol and SU-8 epoxy based polymer are applied as the gain medium. By investigation of the random laser operating lifetimes for both samples, it is shown that SU-8 epoxy based polymer is the preferred host for dye in practical utilizations. Furthermore, we observe that for the sample fabricated based on the polymeric solution of RhB dye doped SU-8 resin, bending the sample leads to an increase of lasing threshold by 39 MW/cm2. This study can pave the way for manufacturing low cost, simply utilized and mechanical controllable random lasers which can also sticks to different surfaces as the marker.
