Abstract

In this paper, a fiber amplifier 1.3 micrometers is presented. It was made of Nd-doped fluoride glass fiber with a core diameter of 9 micrometers , which is developed in our institute. A DBF pulsed laser at (lambda) equals 1.327 micrometers is injected into one end of the fiber as the source of amplified signal and the pumping light source at (lambda) equals 0.8 micrometers is injected into the other end of the fiber through a coated plate that is fully transparent at 0.8 micrometers , totally reflective at 1.3 micrometers wavelength. The amplified signal at 1.3 micrometers wavelength is detected having a gain of 8.5 dB.
