High Power Tolerant SWCNT-BNNT Saturable Absorber for Laser Mode-Locking

Enhanced In-Plane Thermal Conductance of Thin Films Composed of Coaxially Combined Single-Walled Carbon Nanotubes and Boron Nitride Nanotubes

“…In another study, BNNT-wrapped SWCNT films were used as a high power-tolerant saturable absorber and are believed to have a significantly higher optical damage threshold as well as a great potential for various high-power optical applications. 7 Constructing heterostructures from BNNTs and CNTs is a promising way to combine the attracting properties of the two materials. Molecular dynamics simulations show that SWCNT−BNNT features good thermal stability and compressive resistance.…”

“…Using graphene as a basis, vdWHs started from two-dimensional (2D) heterostructures (e.g., graphene, hexagonal boron nitride (BN), 2D metal chalcogenides, and 2D oxides) and developed into a larger field including one-dimensional (1D) heterostructures (e.g., nanowires and nanoribbons) and integration of materials of different dimensions . These vdWHs have been proven to feature unusual properties such as electrical, thermal, optical, and thermoelectric that were not observed previously. − These properties, which could be tailored, enable vdWHs materials readily applicable as functional materials and create various possible applications. The construction of heterostructures can be realized mainly by two strategies.…”

“…However, the insufficient control on the structure parameters, undesired adsorption on the interfaces, and transfer-caused mechanical damages undoubtedly worsen their properties. , On the other hand, the synthesis method has attracted considerable attention due to its tunability and controllability. Among all the synthesis methods, chemical vapor deposition (CVD) technology has become a prevailing route to build the various heterostructures , owing to the high sample quality and outstanding scalability . Compared with the transfer approach, CVD method is capable of preparing high-purity product with larger domain size and adjustable thickness.…”

“…The BNNT layer can also protect the inside SWCNT from oxidation. In another study, BNNT-wrapped SWCNT films were used as a high power-tolerant saturable absorber and are believed to have a significantly higher optical damage threshold as well as a great potential for various high-power optical applications .
