Mamyshev 2R regenerator - Wikipedia

Due to the spectral filtering process, the regenerated pulse is intrinsically shifted from the original frequency. This can be beneficial if wavelength conversion is to be achieved simultaneously the regeneration and therefore channel switching can be considered. However, if one wants to recover an output signal having the initial wavelength, an option of applying another regeneration with the BPF center frequency placed at the original channel center frequency allows to overco… WebApr 1, 2024 · In this letter, we demonstrated an Er-doped Mamyshev oscillator with all-fiber structure, which could generate short pulse duration in low mode-locking threshold. With suitable setting of the cavity structure, the proposed laser generated 83 fs laser pulses at repetition rate of 5.45 MHz and 10-dB spectral bandwidth of 47.4 nm. chipmunk tier
