我们演示了相干克隆的概念，其中使用光学锁相环将高质量光谱稳定光纤激光器的相干特性转移到商用高功率 DFB 半导体激光器 (SCL)。测量并比较了光纤激光器以及自由运行和锁相SCL的线形和频率噪声谱。相干克隆的带宽受到激光调频响应和环路传播延迟等物理因素的限制。分析了这种有限带宽对激光场和自外差干涉测量的影响。
We demonstrate the concept of coherence cloning where the coherence properties of a high-quality spectrally stabilized fiber laser are transferred to a commercially available high-power DFB semiconductor laser (SCL) using an optical phase-lock loop. The lineshapes and frequency noise spectra of the fiber laser and the free-running and phase-locked SCL are measured and compared. The bandwidth of coherence cloning is limited by physical factors such as the laser frequency modulation response and the loop propagation delay. The effect of this limited bandwidth on the laser field and on self-heterodyne interferometric measurements are analyzed.
