| Abstract: | An intracavity coherent coupling Michelson erbium-doped fibre (EDF)laser (MCEDFL) is proposed and demonstrated. By using this lasersystem, we find a means to obtain a maximum power output at the samepumping power level. From the experiment based on fibre Bragggratings (FBGs) with different reflectivities from 6{%} to 100{%},we find that the reflectivity of the FBG plays a vital role inimproving the performance of the MCEDFL. At the same time, the MCEDFLwith a polarizer can be coherently combined effectively. This type ofsystem, in principle, is compatible with other more powerful pumpingmethods, such as cladding pumping, and brings some novel perspectivesto the realization of high power lasers. |
