A para­digm shift is under­way in laser tech­no­logy, marked by the demo­cra­tiza­tion of light. This shift aims to empower indi­vi­du­als bey­ond expert cir­cles, offe­ring the capa­bi­lity to shape and uti­lize light accor­ding to uni­que requi­re­ments. The talk del­ves into the evo­lu­tion of laser tech­no­logy, empha­si­zing its trans­for­ma­tion from a spe­cia­li­zed field to a ubi­qui­tous tool across various indus­tries, par­ti­cu­larly in laser cut­ting, wel­ding, and sur­face struc­tu­ring. Cen­tral to this evo­lu­tion is the con­cept of demo­cra­tiza­tion, which hin­ges on enhan­cing acces­si­bi­lity through sim­pli­city, adap­ta­bi­lity, and per­for­mance.

Laser appli­ca­ti­ons play a cru­cial role in opti­mi­zing and advan­cing tech­no­lo­gies that are of great importance for a sus­tainable energy future. The pre­sen­ta­tion descri­bes the use of laser appli­ca­ti­ons in bat­te­ries, fuel cells, trans­for­mers, and elec­tric motors with a focus on mate­rial pro­per­ties.

In the field of bat­tery tech­no­logy, lasers enable pre­cise machi­ning of elec­trode mate­ri­als to improve per­for­mance and capa­city. This con­tri­bu­tes to the deve­lo­p­ment of effi­ci­ent energy sto­rage solu­ti­ons that are essen­tial for expan­ding rene­wa­ble energy and elec­tri­fy­ing the trans­por­ta­tion sec­tor. In fuel cells, laser appli­ca­ti­ons allow for pre­cise machi­ning of mem­bra­nes and elec­tro­des to increase effi­ci­ency and dura­bi­lity. This sup­ports the rea­liza­tion of clean and emis­sion-free energy sys­tems, pro­vi­ding an alter­na­tive solu­tion to con­ven­tio­nal power gene­ra­tion. Laser appli­ca­ti­ons are also used in trans­for­mers and elec­tric motors to reduce elec­tri­cal los­ses, impro­ving per­for­mance and effi­ci­ency. This sup­ports the deve­lo­p­ment of energy-effi­ci­ent sys­tems. Through fur­ther deve­lo­p­ment and appli­ca­tion of laser appli­ca­ti­ons, the next gene­ra­ti­ons of bat­te­ries, fuel cells, trans­for­mers, and elec­tric motors can be desi­gned, making a signi­fi­cant con­tri­bu­tion to addres­sing the chal­lenges of cli­mate change and resource scar­city.

The laser indus­try in Lithua­nia has rapidly evol­ved into a key player in the glo­bal pho­to­nics mar­ket. This sec­tor show­ca­ses nota­ble strengths in optics, ultra­fast lasers, and laser sys­tems inte­gra­tion. Col­la­bo­ra­tive efforts bet­ween aca­de­mia, rese­arch insti­tu­tes, and indus­try have dri­ven signi­fi­cant advance­ments in laser-based manu­fac­tu­ring, sci­en­ti­fic and medi­cal appli­ca­ti­ons, semi­con, defence and more. Despite chal­lenges, ongo­ing stra­te­gic initia­ti­ves aim to sus­tain Lithuania’s com­pe­ti­tive edge and fos­ter con­tin­ued inno­va­tion within the laser indus­try.

EUV litho­gra­phy is the most advan­ced litho­gra­phy tech­ni­que used in the semi­con­duc­tor indus­try allo­wing mass pro­duc­tion of high per­for­mance micro­chips with low energy con­sump­tion. The light source behind this tech­no­logy is a laser-pro­du­ced plasma (LPP): the TRUMPF Laser Ampli­fier, an extre­mely powerful laser with an average power of 30 kW at roughly 100 ns pulse length, shoots at small metal dro­p­lets at a rate of 50 kHz con­ver­ting the dro­p­lets into a highly-ener­ge­tic plasma, which emits light at 13.5 nm wave­length. This extreme ultra­vio­let light (EUV light) is used to image the chip mask onto the waver with fea­tures as small as a few nano­me­ter. In this talk, we give insights into which extre­mely chal­len­ging requi­re­ments we are facing in this appli­ca­tion and how the TRUMPF laser ampli­fier is capa­ble of ful­fil­ling them.

The pre­sen­ta­tion will be addres­sing all aspects in terms of Indus­tria­liza­tion of AM along the AM manu­fac­tu­ring route – from Design to the finis­hed part, end2end. Spe­cial foci will be spent on vir­tua­liza­tion, new pro­cess approa­ches, finish machi­ning and qua­lity assu­rance. Suc­cess sto­ries from indus­try – machine OEMs as well as end users – will be com­ple­ting the pre­sen­ta­tion.

With the world’s first time ever igni­tion of a bur­ning plasma through iner­tial con­fi­ne­ment of a dense plasma, fusion energy has gar­ne­red glo­bal atten­tion. Plasma con­fi­ne­ment and igni­tion were dri­ven by the world’s lar­gest and most ener­ge­tic laser in this expe­ri­ment: the Natio­nal Igni­tion Faci­lity in the United Sta­tes.

Ger­many, reco­gni­zed for its lea­der­ship in basic rese­arch on magne­tic fusion plas­mas, has not been par­ti­cu­larly active in ICF fusion rese­arch over the past two deca­des. Howe­ver, the Ger­man pho­to­nics and engi­nee­ring sec­tors have played a signi­fi­cant role in pro­vi­ding key com­pon­ents for high energy lasers, and pro­vi­ded mate­ri­als, tar­gets, pre­cis­ion instru­men­ta­tion, elec­tro­nics, and opti­cal tech­no­lo­gies to lea­ding fusion expe­ri­ments world­wide. Addi­tio­nally, Ger­man rese­arch insti­tu­ti­ons main­tain a high level of exper­tise in essen­tial tech­no­lo­gies for laser fusion, as well as in shared tech­no­lo­gies bet­ween magne­tic fusion energy (MFE) and iner­tial fusion energy (IFE), such as rese­arch in fuel cycle or reac­tor mate­ri­als.

Ger­many is stra­te­gi­cally prio­ri­tiz­ing the long-term adop­tion of fusion tech­no­logy, given the robust foun­da­tion of this tech­no­logy. This initia­tive is posi­tio­ned along­side other rene­wa­ble energy sources like solar and wind. The focus on fusion tech­no­logy high­lights the neces­sity for con­ti­nuous rese­arch and deve­lo­p­ment in these cri­ti­cal tech­no­lo­gi­cal areas to main­tain and advance Germany’s lea­der­ship in high-tech tech­no­lo­gies and the energy sec­tor.

This pre­sen­ta­tion will pro­vide an intro­duc­tion to Laser Iner­tial Fusion Energy, offer insights into cur­rent rese­arch from an inter­na­tio­nal and spe­ci­fi­cally Ger­man view­point, and iden­tify oppor­tu­ni­ties within the laser and optics indus­try.
