“…For 1310nm, it was achieved at the masses above 1,500g as indicated by the lack of change or a possible decrease in the power losses as the mass increased. This quick attainment of saturation at his wavelength was associated with the very small power losses change recorded for each additional mass [17]. Meanwhile, at 1550nm, it was achieved at 1,900g and this was related to the balance state of the mass at the upper and lower curved cylinders.…”

Utilization fiber optics macro-bending will be useful for non-destructive applications, such as a mass measurement device. This research, therefore, analyzes the fiber optic power loss due to macro bending by mass loading and explores its possible application as an instrument of mass scale. A single-mode fiber (SMF) with a core diameter of 8.2μm and laser with a wavelength of 1310 nm and 1550 nm are used in this work. Moreover, an optical power meter with a sensitivity of 0.01dBm is applied as the detector while power loss is determined using nine bending cylinders that can produce eighteen bends with a roundtrip system. It is obtained a correlation coefficient R 2 of 0.9910 and 0.9959 corresponding to a sigmoid of 4 parameters for two-wavelength sources of 1310nm and 1550nm, respectively. The results showed mass suppression can produce a power loss with a relatively small error of 19.60%,

“…This means that the WDM needs to withstand the high pump injecting, which also increases the complexity of the system simultaneously. Based on this scheme, the maximum SC output power in a single-stage RFL was maintained at about 40 W [ 12 ] . Further power scaling is limited by the high-power processing capacity of the WDM.…”

The random distributed-feedback fiber laser (RFL) is a new approach to obtain a high-power stable supercontinuum (SC) source. To consider both structure simplification and high-power SC output, an innovative structure achieving a kilowatt-level SC output in a single-stage RFL with a half-open cavity is demonstrated in this paper. It consists of a fiber oscillator, a piece of long passive fiber and a broadband coupler, among which the broadband coupler acting as a feedback device is crucial in SC generation. When the system has no feedback, the backward output power is up to 298 W under the pump power of 1185 W. When the feedback is introduced before the pump laser, the backward power loss can be reduced and the pump can be fully utilized, which could promote forward output power and conversion efficiency significantly. Under the maximum pump power of 1847 W, a 1300 W SC with spectrum ranging from 887 to 1920 nm and SC conversion efficiency of 66% is obtained. To the best of our knowledge, it is the simplest structure used for high-power SC generation, and both the generated SC output power and the conversion efficiency are highest in the scheme of the half-opened RFL output SC.

“…With the intrinsic cavity-free configuration and "modeless" spectrum, random Raman fiber lasers (RRFLs) have unique properties and advantages such as high efficiency/high output power [3] , ultra-broad wavelength tunability [4][5][6] , and flat-amplitude multi-wavelength operation [7,8] . A number of important applications of RRFL have been explored, such as remote sensing [9] , speckle-free imaging [10] , and supercontinuum generation [11,12] . Apart from the studies on improving the performance and pursuing its applications, RRFL has also triggered extensive investigations on its fundamental physical properties.…”

In this Letter, we experimentally investigate fast temporal intensity dynamics and statistical properties of the claddingpumped Er/Yb co-doped random Rayleigh feedback fiber laser (EYRFL) for the first time, to the best of our knowledge. By using the optical spectral filtering method, strong and fast intensity fluctuations with the generation of extreme events are revealed at the output of EYRFL. The statistics of the intensity fluctuations strongly depends on the wavelength of the filtered radiation, and the intensity probability density function (PDF) with a heavy tail is observed in the far wings of the spectrum. We also find that the PDF of the intensity in the central part of the spectrum deviates from the exponential distribution and has the dependence on the laser operating regimes, which indicates some correlations among different frequency components exist in the EYRFL radiation and may play an important role in the random lasing spectrum stabilization process.
