Abstract

The main parameters of SLM-3 laser diode arrays (Inject, Russia) are studied with varying temperature from –50 to +70°C. The absorption efficiency of laser diode array (LDA) radiation in the Nd³⁺:YAG laser crystal is theoretically evaluated in this temperature range. It is found that an increase in the LDA emission spectrum to 10 nm will provide efficient pumping of Nd³⁺:YAG lasers in a wide temperature range without thermal LDA stabilization.

摘要

在 –50 至 +70°C 的不同温度下研究 SLM-3 激光二极管阵列（Inject，俄罗斯）的主要参数。Nd ³⁺ :YAG 激光晶体中激光二极管阵列 (LDA) 辐射的吸收效率在此温度范围内进行理论上的评估。发现将 LDA 发射光谱增加到 10 nm 将在宽温度范围内提供 Nd ³⁺ :YAG 激光器的有效泵浦，而无需热 LDA 稳定性。
