我们对连续波操作中量子级联激光器 (QC) 激光器的相对强度噪声 (RIN) 进行了研究。我们根据相对强度噪声 (RIN) 来分析强度噪声特性。与传统的带间半导体二极管激光器相比,随着 QC 激光器光输出功率的增加,我们获得了不同的 RIN 缩放行为。从半经典噪声模型中,我们发现这个结果是由于级联的有源区域每个包含三个激光水平,因此是 QC 激光器的一个特殊特征。
We present investigations of the the relative intensity noise (RIN) of a quantum cascade laser (QC) laser in continuous wave operation. We analyze the intensity noise properties in terms of the relative intensity noise (RIN). In contrast to conventional interband semiconductor diode lasers we obtain a different scaling behavior of RIN with increasing optical output power for QC lasers. From a semiclassical noise model we find that this result is due to the cascaded active regions each incorporating three laser levels, and is therefore a particular feature of QC lasers.
