4The all-diode-pumped laser system POLARIS——an experimentalist's tool generating ultra-high contrast pulses with high energy显示文摘The development,the underlying technology and the current status of the fully diode-pumped solid-state laser system POLARIS is reviewed.Currently,the POLARIS system delivers 4 J energy,144 fs long laser pulses with an ultra-high temporal contrast of 5 × 1012 for the ASE,which is achieved using a so-called double chirped-pulse amplification scheme and cross-polarized wave generation pulse cleaning.By tightly focusing,the peak intensity exceeds 3.5 × 1020 W cm-2.These parameters predestine POLARIS as a scientific tool well suited for sophisticated experiments,as exemplified by presenting measurements of accelerated proton energies.Recently,an additional amplifier has been added to the laser chain.In the ramp-up phase,pulses from this amplifier are not yet compressed and have not yet reached the anticipated energy.Nevertheless,an output energy of 16.6 J has been achieved so far.Marco Hornung Hartmut Liebetrau Andreas Seidel Sebastian Keppler Alexander Kessler Jrg Krner Marco Hellwing Frank Schorcht Diethard Klpfel Ajay K.Arunachalam Georg A.Becker Alexander Svert Jens Polz Joachim Hein Malte C.Kaluza 2014High Power Laser Science and Engineering2014,2,3:1

11Modeling of the 3D spatio-temporal thermal profile of joule-class Yb3+-based laser amplifiers显示文摘Thermal profile modification of an active material in a laser amplifier via optical pumping results in a change in the material’s refractive index,and causes thermal expansion and stress,eventually leading to spatial phase aberrations,or even permanent material damage.For this purpose,knowledge of the 3D spatio-temporal thermal profile,which can currently only be retrieved via numerical simulations,is critical for joule-class laser amplifiers to reveal potentially dangerous thermal features within the pumped active materials.In this investigation,a detailed,spatio-temporal numerical simulation was constructed and tested for accuracy against surface thermal measurements of various endpumped Yb^3+-doped laser-active materials.The measurements and simulations show an excellent agreement and the model was successfully applied to a joule-class Yb3+-based amplifier currently operating in the POLARIS laser system at the Friedrich-Schiller-University and Helmholtz-Institute Jena in Germany.Issa Tamer Sebastian Keppler Jorg Komer Marco Hornung Marco Hellwing Frank Schorcht Joachim Hein Malte C.Kaluza 2019High Power Laser Science and Engineering2019,7,3:0
