WebWe report the experimental results to continuously tune the coherence length of a semiconductor laser using an optical feedback scheme. The coherence length can be controlled by adjusting the feedback strength when a semiconductor laser operates in a coherence collapse regime. WebIt is defined as the coherence time times the vacuum velocity of light. For example, if the coherence length of a laser is 1 km, the phase relationship between two points along the laser beam, with a distance of 1 km between them, is still significant, but already … where E(t) is the complex electric field at a certain location. The complex degree of … Spontaneous emission is important during the start-up phase of a laser, e.g. when … Sometimes there is a confusion between optical phase noise (as discussed … When the spectral distribution of optical power e.g. of some laser source or other … TOPTICA’s unique CHARM technology (Coherence-advanced regulation … The Schawlow-Townes linewidth is the linewidth of a single-frequency laser with … where is the average intensity..
