| 1 | 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 |
