A new type of graphene oxide (GO) is successfully prepared using an improved modified Hummers method. The Raman shift, X-ray diffraction (XRD), and scanning electron microscope (SEM) measurement techniques are used to characterize the GO. An efficient and compact Q-switched green laser based on Nd:YVO4/PPLN is demonstrated with a few-layered GO as the saturable absorber. Our experimental results show...
We experimentally realized and demonstrated a solid-state, passively Q-switched Nd:YVO4/PPLN green laser with a saturable absorber (SA) based on few-layered MoS2. The MoS2 SA was fabricated by transferring MoS2 nanosheets onto a quartz substrate, and the obtained SA exhibited good transparency from the ultraviolet to near-infrared spectral regions. The modulation depth and the damage threshold of...
