“…Similarly, based on RI and MMFs, Wang et al [75] utilized a graded RI MMF tweezer for three-dimensional trapping of yeast cells, adjusting the position of trapped particles by modifying the fiber tip. Rong et al [76] developed an optical tweezer based on a largediameter four-mode fiber, allowing the extension of resonant fields of higher-order modes for manipulating micro-objects. It is noteworthy that Rong et al also demonstrated that a larger tapered fiber diameter can prolong the lifetime of the tweezer.…”

In recent years, optical fibers have found extensive use in special environments, including high-energy radiation scenarios like nuclear explosion diagnostics and reactor monitoring. However, radiation exposure, such as X-rays, gamma rays, and neutrons, can compromise fiber safety and reliability. Consequently, researchers worldwide are focusing on radiation-resistant fiber optic technology. This paper examines optical fiber radiation damage mechanisms, encompassing ionization damage, displacement damage, and defect centers. It also surveys the current research on radiation-resistant fiber optic design, including doping and manufacturing process improvements. Ultimately, it summarizes the effectiveness of various approaches and forecasts the future of radiation-resistant optical fibers.

“…However, these mentioned CVB fiber lasers operate at fixed wavelengths due to the relatively narrow spectral bandwidth of the mode converter or the mode selector. On the other hand, many applications such as sensing [22], [23], material handling and processing [24], [25], and optical trapping [26], [27] are sensitive to wavelength. In aspect of optical nonlinear application and study, laser with different wavelength may be required.…”

A wavelength-tunable mode-locked cylindrical vector beam (CVB) fiber laser with a dumbbell-shaped structure was proposed and demonstrated experimentally. A homemade broadband long-period fiber grating (LPFG) and a high-birefringence Sagnac fiber loop work as mode converter and comb filter respectively. The mode-locking mechanism is based on the nonlinear polarization rotation (NPR) effect. The central wavelength can be tuned from 1023.257 nm to 1046.123 nm with mode-locked operating state. The laser has a high slope efficiency of 15.75% with the modelocking threshold value of 232.5 mW at the central wavelength of 1041.361 nm. The mode-locked CVB pulses have a repetition rate of 7.06 MHz with the duration of 107 picoseconds. Radially and azimuthally polarized beams can be obtained by eliminating the degeneracy of LP 11 mode, with the purity of 94.86%. This CVB laser with controllable operating wavelength may have potential applications in mode division multiplexed (MDM) systems, optical manipulation, and electron acceleration.
