Abstract
Experiments have been carried out to study the transient radiation-induced absorption in the active core of a double-clad ytterbium fiber and the response of a laser based on it under the exposure of pulsed X-rays. It has been found that the time of loss of laser performance (downtime) under pulsed irradiation increases with an increase in the absorbed of radiation and a decrease in the laser pump power and reaches values of ∼1 ms. An analysis of the experimental results shows that the laser response to the X-rays pulse exposure is determined by radiation-induced losses in the active fiber core. An experimental-calculated method for estimating the radiation reaction of a laser, based on the results of studies of the active fiber, is proposed.
实验研究了双包层镱光纤有源纤芯的瞬态辐射诱导吸收，以及基于双包层镱光纤的激光器在脉冲 X 射线照射下的响应。实验发现，在脉冲辐照下，激光性能损失（停机）时间随着吸收辐射量的增加和激光泵浦功率的降低而增加，达到 ∼ 1 毫秒。对实验结果的分析表明，激光器对 X 射线脉冲照射的响应是由有源光纤芯中的辐射损耗决定的。根据对有源光纤的研究结果，提出了一种估算激光器辐射反应的实验计算方法。
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques.
