A New Erbium Doped Fiber Amplifier

Journal of Applied Sciences, 2009
In this study, a new configuration of an Erbium Doped Fiber Amplifier (EDFA’s) is proposed. Double-pass amplification in a dual-stage using a fiber loop-back is incorporated with a Tunable band pass filter. Spontaneous emission is filtered-out in the mid-section to ensure efficient amplification of the signal as it propagates along the fiber. High gain

In Vitro Metabolism and Analytical Characterization of SLU‐PP‐332 and SLU‐PP‐915: Novel Pan‐ERR Agonists With Doping Potential

Rapid Communications in Mass Spectrometry, Volume 40, Issue 8, 30 April 2026.
ABSTRACT Rationale Estrogen‐related receptor (ERR) agonists such as the drug candidates SLU‐PP‐332 and SLU‐PP‐915 are currently being investigated as exercise mimetics, given their ability to trigger human physiological processes similar to those initiated by actual physical activity.

Controlled Stark shifts in Er$^{3+}$-doped crystalline and amorphous waveguides for quantum state storage

, 2006
We present measurements of the linear Stark effect on the $^{4}$I$_{15/2} \to$ $^{4}$I$_{13/2}$ transition in an Er$^{3+}$-doped proton-exchanged LiNbO$_{3}$ crystalline waveguide and an Er$^{3+}$-doped silicate fiber.

Dysprosium-doped ZBLAN fiber laser tunable from 2.8 {\mu}m to 3.4 {\mu}m, pumped at 1.7 {\mu}m

, 2018
We demonstrate a mid-infrared dysprosium-doped fluoride fiber laser with a continuously tunable output range of 573 nm, pumped by a 1.7 {\mu}m Raman fiber laser. To the best of our knowledge, this represents the largest tuning range achieved to date from
