Black-Phosphorous-Based Pulsed Lasers: 2D Black Phosphorus Saturable Absorbers for Ultrafast Photonics (Advanced Optical Materials 1/2019)

Highly efficient and environmentally stable black-phosphorus-based ultrafast optical switches have been demonstrated by Meng Zhang, Han Zhang and co-workers in article number 1800224 by using light-induced deposition or inkjet-printing techniques. The demonstrated optical devices are capable to generate ultrashort wavelength-tunable pulses covering the spectral region from near- to mid-infrared, providing new potential efficacy for ultrafast laser technology.
