Abstract
This paper describes the latest results on laser oscillation and amplifier operation with Erbium(Er3+)-and Neodymium(Nd3+)-doped fluoride glass fiber. Er3+-doped fluoride fiber amplifiers have a 20 dB gain in the 35 nm wavelength range around 1.55?m. Also, up-conversion lasing is observed in highly Er3+-doped fiber, which produces many kinds of emission. Nd3+-doped fiber amplifiers show a 10 dB gain and a high saturation signal output around 1.33 ?m. The gain limit is discussed in comparison with that of Praseodymium(Pr3+)-doped fiber.Keywords
