AI总结:

本研究通过向激光二极管注入超辐射二极管的非相干光,实现了高功率宽谱非相干光输出,探明了模式转变过程中的光学特性,该系统兼具非相干光放大与相干度可调光源功能。

摘要:

本研究中,向激光二极管中注入功率为2.7 mW的超辐射二极管发射的非相干光,由此产生了谱线宽度为7 nm、功率为140 mW的非相干光。当激光二极管的输出功率降至15 mW时,其出射光的谱线宽度展宽至12 nm。在通过提高注入光功率实现从单模激光到宽谱非相干光的转变过程中,研究人员发现激光二极管的出射光中存在多模激光振荡和噪声谱。该光学系统不仅可用于非相干光的放大,还可作为相干度可转换的光源使用。

英文摘要:

In this study, incoherent light with a spectral linewidth of 7 nm and 140 mW of power was generated from a laser diode into which incoherent light emitted from a superluminescent diode was injected with 2.7 mW of power. The spectral linewidth of the light from the laser diode was broadened to 12 nm when the diode's output power was reduced to 15 mW. In the process of transformation from single-mode laser light to incoherent light with a broad spectrum by increasing injection-light power, multimode laser oscillation and a noisy spectrum were found in the light from the laser diode. This optical system can be used not only for amplification of incoherent light but also as a coherence-convertible light source.
