HIGH-POWER OPTICAL SOURCE USING DYE-DOPED POLYMER OPTICAL-FIBER

Basic characteristics of organic-dye doped polymer optical fibers (DPO Fs) are demonstrated. The devices contain laser dye, such as Rhodamine 6G (R6G) and Rhodamine B (RE) in the core region. Firstly, amplificat ion characteristics of DPOF amplifiers (POFAs) excited by a pulse-oper ated, doubled Nd:YAG laser are demonstrated, e.g., a 250 mm-length of RB-POFA gives 1 kW (30 dB) of amplified signal at 591 nm. Next, an all solid state system of RE DPOF laser (POFL) is discussed by numerical simulation and the experimental result of high-power amplified spontan eous emission (ASE) by strong excitation of DPOF is shown.
