Although the spectral range for the reported experiment was 2020nm to 2120nm [8].For the first time diode pumped HDFA was demonstratedby researcher Simakov et al(2016)He reported the peak gain of 25dB at 2040nm [5]. Resonantly pumped holmium-doped fiber amplifier was reported by Hemming et al(2014) which is highest power amplifier, it is capable of operating in an atmospheric transmission window >2.05µm [6].…”

УСИЛЕНИЕ ПИКОСЕКУНДНЫХ ИМПУЛЬСОВ ДВУХМИКРОННОГО ДИАПАЗОНАВ данной работе был усилен слабый сигнал импульсного гольмиевого волоконного лазе-ра с длиной волны излучения 2065 нм. Длительность импульсов не превышала 52 пс. Задающий сигнал, мощность которого составила 0,073 мВт, усилили до 45 мВт, что соответствует коэффи-циенту усиления 28 дБ. Форма усиленного спектра остается неизменной до значения коэффици-ента усиления 22,3 дБ, далее наблюдалась деформация усиленного спектра. Средняя мощность на выходе усилителя до спектральной деформации составила 12,5 мВт.Ключевые слова: гольмиевый волоконный лазер, импульсный волоконный лазер, уси-ление пикосекундных импульсов, синхронизация мод, волоконный усилитель, гольмиевый усили-тель, двухмикронное излучение.

“…Among them, the development of high-power lasers for LIDAR (due to its excellent atmospheric transmission), gas sensing, medicine, material processing, and nonlinear optical conversion in the mid-infrared. [1][2][3][4][5] In this context, many efforts have been made to improve the performance of holmium-doped fiber lasers. One interesting strategy is using a tapered-doped fiber to increase the absorption of the pump along the doped core, which consequently helps improve the power conversion between the pump and signal.…”

Thermal effects on tapered holmium-doped fiber amplifiers

The temperature response of a tapered holmium-doped fiber amplifier and its impact in the performance of fiber lasers and temperature fiber sensors has numerically been analyzed. Different pump schemes and different longitudinal shapes of the tapered-doped fiber were investigated, and it was found that a parabolic shape of the tapered fiber amplifier in a co-propagating pump scheme shows the highest sensitivity to temperature changes. In particular, the temperature sensitivity of the amplified signal was 2.5 × 10 −4°C for 1 W of pump power and 1 m of doped fiber length. In addition, this sensitivity can be increased up to 10 times for fiber lengths shorter than 1 m and pump powers lower than 300 mW. Our results can be used to describe the temperature response of tapered fiber amplifiers in the mid-infrared spectral region and contribute with new information for the development of fiber lasers and fiber temperature sensors.
