A dual-wavelength Q-switched fiber laser based on reduced graphene oxidesXinning Huang’s research team’s report demonstrates a dual-wavelength stable Q-switched Er-doped fiber (EDF) laser with a reduced graphene oxide (rGO)-based saturable absorber. The rGO is prepared by depositing the graphene oxide on fluorine mica (FM) usi...Nov 27, 2019 -
Kuanguo Li’s research team predicted that A porous Au-Ag hybrid nanoparticle array with broadband absorption and high-density hotspots for stable SERS analysisConstructing high-density hotspots is of crucial importance in surface enhanced Raman scattering (SERS). Kuanguo Li’s research team present a large-area and broadband porous Au–Ag hybrid nanoparticle array which was fabricated by an ultra-thin alumina mas...Nov 27, 2019 -
High-Sensitivity and Long-Life Microchannel Plate Processed by Atomic Layer DepositionAs a key component of electron multiplier device, a microchannel plate (MCP) can be applied in many scientific fields. Pure aluminum oxide (Al2O3) as secondary electron emission (SEE) layer were deposited in the pores of MCP via atomic layer deposition (ALD...Nov 27, 2019 -
All-fiber polarization interference filter based uniform multiwavelength erbium-doped fiber laserYishan Wang’s research team demonstrate a compact and stable room-temperature multiwavelength erbium doped fiber laser by employing 45 degrees tilted fiber gratings based on an all-fiber polarization interference filter. Benefiting from the filter, the cha...Nov 27, 2019 -
Direct Amplification of High Energy Pulsed Laser in Fiber-Single Crystal Fiber with High Average PowerZhi Yang’s research team experimentally study a laser master oscillator power amplifier (MOPA) system consisting of a fiber amplifier and a two-stage Yb:YAG single crystal fiber (SCF). The nonlinear stimulated Raman scattering (SRS) is avoided by limiting ...Nov 27, 2019
