Linewidth analyzer
The HighFinesse Linewidth Analyzers are high-end optical instruments for measuring, analyzing and controlling frequency and intensity noise of laser light sources. By combining an interferometric working principle with ultra-low noise electronics, a superb sensitivity is achieved. Nettet29. jan. 2024 · In this paper, we demonstrate a narrow-linewidth tunable fiber laser based on laser-induced graphene (LIG) paper-heated fiber Bragg grating (FBG) with low voltage. A linewidth of less than 600 Hz is achieved by the combination of a piece of unpumped Er-doped fiber and an FBG. Changing the temperature of the FBG will result in the …

Nettet21. apr. 2012 · The linewidth of a polarization-locked external cavity diode laser (ECDL) is explored employing heterodyne as well as self-heterodyne measurements. We use a model capable of providing the individual contributions of white, pink and red noise to the overall linewidth to analyze the measured beat spectra. These spectra are obtained …
Nettet10. apr. 2024 · The self-injection-locked diode laser can significantly reduce the linewidth down to a sub-100 kHz level but requires optical filtering that is much narrower than the laser cavity linewidth. Such optical filtering is usually sophisticated and beyond the capability of the normal dielectric coating approach. Here we develop a 0.16 nm …
