摘要：

To date, although high small signal gains have been achieved, the power amplifier performance of PDFFA's has been disappointing. In this letter, we report a PDFFA exhibiting efficient operation in both the large and small signal regime. The amplifier, based on a high NA fluoride fiber, exhibited a maximum small signal gain of 29 dB and a low-pump small signal efficiency of 0.13 dB/mW. In the saturated regime a maximum output power of 212 mW was achieved. In this format, the signal-out versus pump-in characteristic exhibited a slope efficiency of 30%, representing the most efficient conversion from pump to signal yet reported. Detailed spectral characterization reveals small signal gain in excess of 20 dB over a wavelength range of almost 50 nm and in excess of 100 mW saturated output available over a 30 nm wavelength range.
