Abstract
We report on a compact 808 nm diode-pumped passively Q-switched (PQS) Nd:YVO4 laser at 1064 nm with black phosphorus (BP)/ indium selenide (InSe) heterostructure as a saturable absorber (SA). When the transmission of the output coupler (OC) was 30%, the maximum continuous-wave (CW) output power of 10.3 W was obtained with a slope efficiency of 52.4% under the incident pump power of 22 W. The maximum average output power of 3.1 W was obtained at 9.29 W pump power, corresponding to the repetition rate of 598 kHz and the pulse width of 455 ns during pulse operation, further power scaling was limited by the damage threshold of the saturable absorber mirror (SAM). The results sufficiently validated that two-dimensional (2D) BP/InSe heterostructure could be used as an optical modulator for near-IR pulsed laser sources.
期刊介绍：
The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope.
Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees.
General topics covered include:
• Optical and photonic materials (inc. metamaterials)
• Plasmonics and nanophotonics
• Quantum optics (inc. quantum information)
• Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers)
• Coherence, propagation, polarization and manipulation (classical optics)
• Scattering and holography (diffractive optics)
• Optical fibres and optical communications (inc. integrated optics, amplifiers)
• Vision science and applications
• Medical and biomedical optics
• Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy)
• Imaging and Image processing
