Continuously wavelength-tunable mode-locked Tm fiber laser using stretched SMF-GIMF-SMF structure as both saturable absorber and filter
H Li, F Hu, Y Tian, P Wang, J Zhang, S Xu - Optics express, 2019 - opg.optica.org
We demonstrate, for the first time, use of a stretched single mode-graded-index multimode-
