Marine biofouling seriously affects human marine exploitation and transportation activities, to which marine antifouling(AF) coatings are considered to be the most cost-effective solution. Since the mid-20th century, human beings have dedicated their efforts on developing AF coatings with long cycle and high performance, leading to a large number of non-target organisms? distortion, death and marine environmental pollution. Polydimethylsiloxane(PDMS), is considered as one of the representative environment-friendly AF materials thanks to its non-toxic, hydrophobic, low surface energy and AF properties. However, PDMS AF coatings are prone to mechanical damage, weak adhesion strength to substrate, and poor static AF effect, which seriously restrict their use in the ocean. The rapid development of various nanomaterials provides an opportunity to enhance and improve the mechanical properties and antifouling properties of PDMS coating by embedding *** on our research background and the problems faced in our laboratory, this article presents an overview of the current progress in the fields of PDMS composite coatings enhanced by different nanomaterials, with the discussion focused on the advantages and main bottlenecks currently encountered in this field. Finally, we propose an outlook, hoping to provide fundamental guidance for the development of marine AF field.

Dual-wavelength all-fiber Q-switched fiber laser using bismuth-doped fiber as saturable absorber

引用

Optoelectronics Letters 2024年第3期20卷 147-151页

作者： Aruna Ghosh Abdulkadir Mukhtar Diblawe Uttam Kumar Samanta Moh Yasin Sulaiman Wadi Harun Mukul Chandra paul Fiber Optics and Photonics Division CSIR-Central Glass and Ceramic Research InstituteKolkata 700032India Physics Department Jadavpur UniversityKolkata 700032India Photonics Engineering Laboratory Department of Electrical EngineeringUniversity of MalayaKuala Lumpur 50603Malaysia Department of Physics Faculty of Science and TechnologyAirlangga UniversitySurabayaIndonesia

A passively Q-switched all-fiber laser is demonstrated using a 10-cm-long bismuth-doped fiber(BDF) as a saturable absorber(SA). The dual-wavelength operation was obtained due to the nonlinear effect inside the fabricated BDF, which has a high germanium content. Stable Q-switched pulses were obtained at the dual synchronous wavelengths of 1 530.1 nm and 1 531.1 nm. When the pump power is tuned from 105.3 mW to 191.0 mW, the repetition rate can be varied from 82.6 kMz to 117.6 kHz. The maximum pulse energy and average output power were 83.4 nJ and 9.8 mW, respectively while the minimum pulse width was 8.5 μs at the maximum pump power of 191.0 mW. Our results indicate that BDF could be a promising alternative optical modulator for pulsed fiber laser application.
