论文摘要
条纹摄像机是测量脉冲发射的最常见和方便的设备之一，例如从半导体的光源，具有比索的时间分辨率。但是，它们在可见范围内最敏感，并且在红外和电信方面具有低或可以忽略的效率。在这项工作中，我们提出了一个基于总频率生成的频率转换，该频率转换为可见信号，同时保留其时间属性，从而可以用条纹摄像头检测到它们。我们通过转换量子点激光器的发射来证明和验证设备的功能。
Streak cameras are one of the most common and convenient devices to measure pulsed emission e.g. from semiconductor lightsources with picosecond time resolution. However, they are most sensitive in the visible range and possess low or negligible efficiency in the infrared and telecom regime. In this work, we present a frequency conversion based on sum-frequency generation that converts infrared to visible signals while preserving their temporal properties, making them detectable with a streak camera. We demonstrate and verify the functionality of our device by converting the emission from a quantum dot laser.
