| 1 | Yb-doped large-pitch fibres: effective single-mode operation based on higher-order mode delocalisation显示文摘Rare earth-doped fibres are a diode-pumped,solid-state laser architecture that is highly scalable in average power.The performance of pulsed fibre laser systems is restricted due to nonlinear effects.Hence,fibre designs that allow for very large mode areas at high average powers with diffraction-limited beam quality are of enormous interest.Ytterbium-doped,rod-type,large-pitch fibres(LPF)enable extreme fibre dimensions,i.e.,effective single-mode fibres with mode sizes exceeding 100 times the wavelength of the guided radiation,by exploiting the novel concept of delocalisation of higher-order transverse modes.The non-resonant nature of the operating principle makes LPF suitable for high power extraction.This design allows for an unparalleled level of performance in pulsed fibre lasers. | Jens Limpert Fabian Stutzki Florian Jansen Hans-Jurgen Otto Tino Eidam Cesar Jauregui Andreas Tunnermann | 2012 | Light(Science & Applications)2012，1，1： | 16 |
| 2 | Watt-scale super-octave mid-infrared intrapulse difference frequency generation显示文摘The development of high-power,broadband sources of coherent mid-infrared radiation is currently the subject of intense research that is driven by a substantial number of existing and continuously emerging applications in medical diagnostics,spectroscopy,microscopy,and fundamental science.One of the major,long-standing challenges in improving the performance of these applications has been the construction of compact,broadband mid-infrared radiation sources,which unify the properties of high brightness and spatial and temporal coherence.Due to the lack of such radiation sources,several emerging applications can be addressed only with infrared(IR)-beamlines in largescale synchrotron facilities,which are limited regarding user access and only partially fulfill these properties.Here,we present a table-top,broadband,coherent mid-infrared light source that provides brightness at an unprecedented level that supersedes that of synchrotrons in the wavelength range between 3.7 and 18μm by several orders of magnitude.This result is enabled by a high-power,few-cycle Tm-doped fiber laser system,which is employed as a pump at 1.9μm wavelength for intrapulse difference frequency generation(IPDFG).IPDFG intrinsically ensures the formation of carrierenvelope-phase stable pulses,which provide ideal prerequisites for state-of-the-art spectroscopy and microscopy. | Christian Gaida Martin Gebhardt Tobias Heuermann Fabian Stutzki Cesar Jauregui Jose Antonio-Lopez Axel Schulzgen Rodrigo Amezcua-Correa Andreas Tunnermann Ioachim Pupeza Jens Limpert | 2018 | Light(Science & Applications)2018，7，1： | 8 |
| 3 | Modal energy transfer by thermally induced refractive index gratings in Yb-doped fibers显示文摘Thermally induced refractive index gratings in Yb-doped fibers lead to transverse mode instability(TMI)above an average power threshold,which represents a severe problem for many applications.To obtain a deeper understanding of TMI,the evolution of the strength of the thermally induced refractive index grating with the average output power in a fiber amplifier is experimentally investigated for the first time.This investigation is performed by introducing a phase shift between the refractive index grating and modal interference pattern,which is obtained by applying a pump power variation to the fiber amplifier.It is demonstrated that the refractive index grating is sufficiently strong to enable modal energy coupling at powers that are significantly below the TMI threshold if the induced phase shift is sufficiently large.The experiments indicate that at higher powers,the refractive index grating becomes more sensitive to such phase shifts,which will ultimately trigger TMI.Furthermore,the experimental results demonstrate beam cleaning above the TMI threshold via the introduction of a positive phase shift.This finding paves the way for the development of a new class of mitigation strategies for TMI that are based on controlling the phase shift between the thermally induced refractive index grating and modal interference pattern. | Christoph Stihler Cesar Jauregui Andreas Tünnermann Jens Limpert | 2018 | Light(Science & Applications)2018，7，1： | 5 |
