Results in brief

SEmiconductor disk Lasers for EffiCient Terahertz generation

The Fellowship, entitled “SEmiconductor disk Lasers for EffiCient Terahertz generation” (SELECT) has successfully reached its primary goal of training a talented researcher, Dr. Ksenia Fedorova, through a research project in the fast-growing field of science, technology and industrial applications of THz-emitting semiconductor-based lasers. The success of the innovative multidisciplinary project has led to the development of stable, ultra-efficient, compact THz lasers for a number of applications ranging from spectroscopy and biomedical imaging to security screening and quality control. The overall objectives of the project were: (i) Broadening of the Fellow’s expertise in semiconductor lasers and Terahertz (THz) technology with a focus on industrial applications; (ii) Development of novel models for optimum design of nonlinear crystals to meet power and wavelength goals; (iii) Design of advanced techniques for stable high-power dual-wavelength operation of semiconductor disk lasers; (iv) Development of the stable highly-efficient laser system generating THz radiation with practical output power; and (v) Applications of the laser systems in THz spectroscopy and biomedical imaging fields. During the project duration excellent progress has been made: detailed numerical model for design of nonlinear crystals has been developed for ultra-efficient THz generation, stable high-power dual-colour semiconductor disk lasers operating in the near-IR region, as well as stabilised ultra-efficient THz-emitting lasers for application in THz spectroscopy and biomedical imaging, have been designed and demonstrated, and novel operating regimes for broadly-tunable THz generation have been identified. The obtained results are enormously encouraging and confirm the great potential of this technology to enable future development of stable, room-temperature, high-performance laser sources capable of generating THz radiation with practical output power for the range of scientific, industrial, and biomedical applications. The results achieved and laser prototypes developed during the SELECT project have shown that compact, room-temperature, highly-efficient THz laser sources could be made more readily available to both industry and society as a whole. This will certainly enhance EU scientific excellence.

Project objective

The primary goal of this Fellowship, entitled “SEmiconductor disk Lasers for EffiCient Terahertz generation” (SELECT), is totrain a talented researcher through a research project focused on the development of high-performance laser sources basedon semiconductor disk lasers and novel periodically poled ferroelectric and semiconductor crystals that can offer an accessto new wavelengths not covered by available gain media, particularly in the THz spectral region, which are desired for THzspectroscopy, Biomedical imaging, and Safety and Security applications. The novel high-performance vertical-external-cavitysurface-emitting-laser, with remarkable output parameters, will be used as a source of ultra-efficient THz emission in the0.8-3THz spectral window based on difference frequency generation in advanced quasi-phase-matched crystals. Thesuccess of the interdisciplinary project will lead to a number of multidisciplinary disruptive innovations in Photonics withsignificant scientific, technical, economic and social impact, from spectroscopy and biomedical imaging to security screeningand quality control.The Fellow - Dr. Ksenia Fedorova - will be trained in the fast growing field of science, technology and industrial applicationsof semiconductor lasers and THz technology, receiving access to a unique training experience at the host – Philipps-Universität Marburg, and at academic and industrial secondments: Aston University, Innolume GmbH, M-Squared LasersLtd. The project will enable the Fellow to be a rare asset to European research; she will gain a set of multidisciplinaryprofessional skills in both theoretical and practical fields, starting from the laser system design and fabrication and finishingwith implementing the final product into real industrial applications.The SELECT outputs will be relevant to the EU Photonics industry through offering new efficient compact THz lasers, whichwill also contribute to the enhancement of EU scientific excellence.
