Introduction

Solid-state lasers and fiber lasers play an increasingly important role in industrial processing, communications, medical treatment, lidar, and scientific research.

As the core working material in solid lasers and fiber lasers, laser materials convert pump light into The laser is replaced by a laser of a specific wavelength. Commonly used laser materials include laser glass, laser crystal, laser ceramic and laser fiber. The concentration of active ions is One of the key performance indicators of laser materials, it plays an important role in the performance evaluation of laser materials and the development of lasers.

The test of the concentration of activated ions in laser materials lacks standardized test methods and cannot meet the development requirements of laser materials, lasers and laser technology.

In order to meet the development needs, it is urgent to formulate unified testing standards.

This document was developed to define in one document common test methods for the concentration of active ions in different types of laser materials.

There are inductively coupled plasma optical emission spectrometry (ICP-OES), inductively coupled plasma mass spectrometry (ICP-MS), X-ray fluorescence spectrometry (XRF), electron probe microanalysis (EPMA) and glow discharge mass spectrometry (GD-MS), etc.

The formulation of this document is conducive to the research and development, production and application of laser materials, and is conducive to the standardized application of laser material product standards.
