Impact of Intracavity Power Variations toward Ultrashort Pulse Generation

Applied Sciences, 2023
This study demonstrates a passive mode-locked erbium-doped fiber laser with a graphene nanoplatelet-saturable absorber (GNP-SA) that generates ultrashort pulses within femtosecond pulse duration. The GNP-SA is fabricated via a direct transfer approach by
