| Abstract;Practical 1.3.MU.m-band optical fiber amplifier/laser with reliable 1-.MU.m-band pump laser diode modules and efficient praseodymium-doped In-based fluoride fibers are presented. High-power 1-.MU.m-band laser diode modules have been developed for most efficient pumping. Praseodymium-doped In-based fluoride fibers are characterized using measurable parameters, and amplified characteristics are theoretically analyzed. Signal output power of +16.2dBm (42mW) is achieved for a praseodymium-doped In/Ga-based fluoride fiber amplifier pumped by four 1.01-.MU.m laser diode modules. Lasing output power of 10-28mW in tuning wavelength range of 1.29-1.33.MU.m is achieved for a ring laser with a praseodymium-doped In/Pb-based fluoride fiber amplifier, a wavelength tunable optical bandpass filter and a 10-dB coupler.
