Passive mode-locked Nd:YVO4 laser using a multi-walled carbon nanotube saturable absorber

Q-Switched Ultrafast TDFL Using MWCNTs-SA at 2 µm Region

“…[24], [25] As far as the authors known, there are only few works reported regarding the usage of MWCNTs as saturable absorber in fibre laser application. For instance, Zhang et al [23] employs MWCNTs as saturable absorber for mode locking of neodymium-doped yttrium vanadate (Nd:YVO4) laser. In other work, Q-switched neodymium-doped yttrium aluminum garnet (Nd-YAG) laser is demonstrated using MWCNTs based saturable absorber as Q-switcher.…”

“…It has attracted attentions in photonic research field especially in nonlinear optic applications due to the cost effectiveness, which will reduce up to 20% -50% of MWCNTs material. [23] The development of MWCNTs material does not require special techniques or conditions so thus will generate high productivity. MWCNTs are mechanically stronger, thermally stable as well as can absorb more photons energy per nanotubes due to high density of mass at the multi-walls.…”

Broad spectral pulse operation of 2 μm Tm:YAP laser based on reflection-type carbon nanotube absorber

“…Single walled carbon nanotube saturable absorbers (SWCNT SAs) have unique nanostructures that fea ture interesting optical properties beside curious elec trical, chemical, and mechanical properties [20,21]. SWCNT SAs exhibit high speed third order optical nonlinearity and saturable absorption, which make them a promising replacement for semiconductor based ultrafast saturable absorber mirrors (SESAMs) [22].…”

Broadband single-walled carbon nanotubes absorber for solid-state ultrafast lasers

“…In this paper, we have adopted a novel approach [20][21][22][23][24][25][26][27][28][29][30] to fabricate an SWCNT absorber for various high power mode locking solid state lasers operating at different wavelengths, e.g., 1, 1.34, and 2 μm. The absorber allows mode locking operations at the wave lengths of 1 and 1.34 μm and Q switched and mode locking operation at 2 μm.…”
