摘要

摘要:本文报道了一种自制的用于激光的钬铝锗共掺二氧化硅光纤的基本光谱特性。我们给出了光纤在激光作用下的基态和激发态吸收光谱以及上转换发射光谱，用于绘制Ho3+离子的能级图。我们讨论了评估Ho3+ 2-µm荧光动力学的方法，重点是测量5I7水平的荧光寿命和5I6水平的非辐射衰变时间。导出了适用于荧光衰减曲线拟合的简单解析公式，可用于掺钬光纤激光器的精确建模。

Spectroscopic Properties of Holmium-Aluminum-Germanium Co-doped Silica Fiber

ABSTRACT We report the basic spectroscopic properties of a home-made holmium-aluminum-germanium co-doped silica fiber, designed for laser applications. We present the ground-state and excited-state absorption spectra of the fiber along with the up-conversion emission spectrum under laser action, which served for making an energy levels’ diagram of Ho3+ ion. We discuss the ways to assess the kinetics of Ho3+ 2-µm fluorescence, focusing on measuring fluorescence lifetime from 5I7 level and non-radiative decay time from 5I6 level. The simple analytical formulae, applicable for fitting of the fluorescence decay curve, are derived, which can be useful for precise modeling of holmium-doped fiber lasers.

期刊介绍： Fiber and Integrated Optics , now incorporating the International Journal of Optoelectronics, is an international bimonthly journal that disseminates significant developments and in-depth surveys in the fields of fiber and integrated optics. The journal is unique in bridging the major disciplines relevant to optical fibers and electro-optical devices. This results in a balanced presentation of basic research, systems applications, and economics. For more than a decade, Fiber and Integrated Optics has been a valuable forum for scientists, engineers, manufacturers, and the business community to exchange and discuss techno-economic advances in the field.
