在光纤中传播的光辐射被用来在切割的光纤端面和光纤连接器上沉积市售的单壁碳纳米管。由于光学吸收引起的加热引起的热泳动被认为是导致沉积过程的可能原因。单壁碳纳米管在较宽的波长范围内具有快速的可饱和吸收，并且所演示的技术是一种非常简单和廉价的方法，用于制造光纤激光器被动锁模的光纤集成可饱和吸收器。在1560nm处，掺铒光纤激光器的脉冲宽度为247fs，在1070nm处，掺镱光纤激光器的脉冲宽度为137fs。(C) 2007年美国光学学会。
Optical radiation propagating in a fiber is used to deposit commercially available, single-walled carbon nanotubes on cleaved optical fiber end faces and fiber connectors. Thermophoresis caused by heating due to optical absorption is considered to be a likely candidate responsible for the deposition process. Single-walled carbon nanotubes have a fast saturable absorption over a broad wavelength range, and the demonstrated technique is an extremely simple and inexpensive method for making fiber-integrated, saturable absorbers for passive modelocking of fiber lasers. Pulse widths of 247 fs are demonstrated from an erbium-doped fiber laser operating at 1560 nm, and 137 fs pulses are demonstrated from an amplified Yb-doped fiber laser at 1070 nm.
