We report the experimental demonstration and record performance of two-stage broadband, high gain polarization-maintaining (PM) Ho-doped fiber amplifiers (HDFAs) at a signal wavelength of λs = 2051 nm. We begin by presenting a new PM Ho-doped fiber
Simulation and design of a multistage 10W thulium-doped double clad silica fiber amplifier at 2050nm

A careful comparison of experiment and theory is important both for basic research and systematic engineering design of Thulium fiber amplifiers operating in the 2 μm region for applications such as LIDAR or spectroscopy (e.g. CO2 atmospheric absorp

We have performed experiments to elucidate the mechanism of photosensitivity in rare-earth-doped fluorozirconate (ZBLAN) glasses. Glasses doped with Ce, Tb, Tm, and Pr were studied. Permanent holographic gratings were written in bulk samples using 24

More than 450 fiber Bragg gratings have been fabricated in line during the draw process in a period of 1 h with single pulses of a KrF excimer laser. Arrays of gratings have been written at different Bragg wavelengths by using an automated, computer-

We show that permanent optical gratings can be photowritten into simple silicate glasses by exposure to interfering beams of an Ar-ion laser after the glass has been treated by x rays. Gratings with index modulations as large as Deltan = 10(-5) can b

The 1620-1700 nm region of the optical spectrum is important as it contains numerous molecular resonance lines of chemical species. We have investigated, theoretically and experimentally, the possibility of designing an efficient tunable wavelength c

The contribution of impurity ions to the total optical absorption of a heavy metal fluoride glass has been determined at 532 and 1064 nm. Four ZrF4-BaF2-LaF3-AlF3-NaF glasses were prepared from various purity raw materials. The absorption coefficient

The optical attenuation induced in two erbium-doped fibers by 60Co (gamma) -ray exposures to 200 krad has been measured at 3 different dose rates, approximately, 35, 1000, and 20,500 rad/min. The growth of the induced loss was measured at 980, 1300,

The optical attenuation induced in 6 Navy Qualified Parts List (QPL) fibers by 60Co 'y-ray exposures to 106 rad has beenmeasured at 3 different dose rates: 26, 1000, and 20,500 rad/min. The loss in the Corning, Lucent and Plasma Optical Fibermultimod
Experimental data are presented to show that Ge(1) and Ge(2) centers are induced by trapping photoinduced electrons from the conduction band, in agreement with our previous proposal that both are trapped electron centers. The spacing (Lambda) depende
