102 fs pulse generation from a long-term stable, inkjet-printed black phosphorus-mode-locked fiber laser.
Xinxin Jin, Guohua Hu, Meng Zhang, Yuwei Hu, Tom Albrow-Owen, Richard CT Howe, Tien-Chun Wu, Qing Wu, Zheng Zheng, Tawfique Hasan
Jul 20, 2018
We demonstrate a long-term stable, all-fiber, erbium-doped femtosecond laser mode-locked by a black phosphorus saturable absorber. The saturable absorber, fabricated by scalable and highly controllable inkjet printing...
Gigahertz pulse source by compression of modelocked VECSEL pulses coherently broadened in the normal dispersion regime
We report the coherent spectral broadening of the output of a mode-locked VECSEL emitting 455 fs pulses at 1007 nm in the normaldispersion regime. Subsequent compression of the fiber outputs using a transmission grating...

Understanding the transfer of spin angular momentum is essential in modern magnetism research. A model case is the generation of magnons in magnetic insulators by heating an adjacent metal film. Here, we reveal the initial steps...
A Parallel Hybrid Feature Selection Approach Based on Multi-Correlation and Evolutionary Multitasking
Particle swarm optimization (PSO) has been successfully applied to feature selection (FS) due to its efficiency and ease of implementation. Like most evolutionary algorithms, they still suffer from a high computational burden...
