“…Based on the results of this work, we suggest having the dopants more diluted and along all the fiber in order to further improve the system; overcoming in this way, adverse effects related to high concentration such as quenching. An additional enhancement for the second stokes generation is possible by heating the fiber some tens of degrees Celsius because the ASE emission becomes IR-shifted [7]. Other regions may be enhanced by co-doping the system with other rare-earths.…”

“…A notorious improvement of these systems, as we propose in this work, consists on splicing pieces of Yb3+-doped fiber (YbDF) to the RAF. In such scheme, the YbDF produces in-axis broad-band amplified spontaneous emission (ASE) that ranges from the pump wavelength to around 1160 nm [7,13]. The fiber used here has a core of 4.2 µm in diameter and 10 000 ppmwt concentration of Yb.…”

“…Apart from these motivations, a frequency-doubled version to 550-600 nm would benefit other medical applications and may serve to generate artificial stars that are used as guides for adaptive astronomical telescopes [5][6][7]. RFL's operate under the Simulated Raman Scattering (SRS) that is a non-linear effect; as a consequence, they require high-pump powers and long fibers to operate.…”

-Once reached the threshold for operation, Raman fiber lasers with high output couplers convert the pump signal into stokes signals very efficiently. However, high threshold implies lower overall efficiency and hence the ratio slope efficiency-to-threshold power (i.e., the figure of merit) is low. By maintaining the slope efficiency value and decreasing threshold, the figure of merit (overall efficiency) increases. In this work, we have increased this parameter from 57 (for a typical Raman configuration) to 105 (investigated configuration). This represents an 84% improvement. A threshold of 2.9 watts decreased to 1.3 watts by inserting 1.27 m of ytterbium doped fiber into a 350-m Raman cavity. Another way for obtaining similar results was explored by enlarging the cavity more than double (to 750 m) but power delivery decreased by 20% due to additional fiber loss. The system studied is shorter and more efficient than typical configurations and might be considered given its simplicity. Advantages, disadvantages and other ways for obtaining similar results are discussed.

“…This situation can be further improved by changing the ratio between absorption and emission cross-sections and thus diminishing the gain in the unwanted spectral domains by heating the fiber [25]. Self-heating of the fiber is proved to be an advantageous technique due to simplicity and reliability of the laser construction.…”

“…Simple step-index fiber technology is already well established. Several approaches helping to expand the operating range of such Yb-doped fibers have been reported: strong cavity coupling [21,22], core-pumping in the absorption tail [17,23,24,25], active [17,25,26] and passive [27] heating of the active fiber and other techniques [28]. As a result, 10 W level of optical power has been successfully overcome.…”

Abstract:In this brief review we consider the main factors determining the oscillation spectral range of cladding-pumped ytterbium-doped fiber lasers (YDFLs) and the results obtained for lasers emitting at various wavelengths. Like erbium-doped fiber amplifiers we suggest dividing the oscillation spectral range of YDFLs into three bands, namely: convenient (C-band), short (S-band), and long (L-band). Polymer-coated double-clad fibers with the inner cladding having a size of more than 100 µm allows one to get efficient operation in the convenient range (Cband): 1060 − 1130 nm. To get an oscillation within the S-band (976 − 980 nm and 1020 − 1060 nm) it is necessary to use active fibers with a small square of the inner cladding. Heating of the active fiber gives the possibility to get lasing within the L-band λ > 1130 nm). Another way to get an emission in this spectral range is by the application of long-wave pumping by a C-band YDFL. Also, we indicate some features that require further study.
