High-power (1200 W) and high-gain (36 dB, approximately 4000 times) amplification has been achieved in a graded-index (GI) polymer optical fiber amplifier (POFA) with 0.3 W input signal under optimized amplification conditions suggested from theoretical analysis. High gain of more than 25 dB (320 times) is expected through the wavelength region of 540-610 nm using Rhodamine 6G, Rhodamine B, and Rhodamine 101-doped GI POFA. The amplification at 649-nm wavelength where POF has a low loss window of transmission was achieved in an Oxazine 4 perchlorate-doped GI POFA.
