TOPTICA Pho­ton­ics, found­ed in 1998 near Munich (Ger­many), is a pri­vate­ly held laser man­u­fac­tur­ing com­pa­ny. More than 300 peo­ple devel­op, pro­duce and pro­vide research-grade lasers for sci­en­tif­ic appli­ca­tions as well as indus­try-grade lasers for OEM inte­gra­tion.

Laser sys­tems with high­est pre­ci­sion, reli­a­bil­i­ty and longevi­ty

Key tech­nolo­gies com­prise tun­able sin­gle fre­quen­cy diode lasers from 190 nm to 4000 nm, ps and fs pulsed fiber lasers from 488 nm to 2300 nm, fre­quen­cy combs from 420 nm to 2200 nm, mul­ti-col­or laser engines, THz sys­tems for fre­quen­cy-domain or time time-domain spec­troscopy, and high-pow­er laser diodes & semi­con­duc­tor opti­cal ampli­fiers.

Lasers for quan­tum tech­nolo­gies

For its impor­tant mar­ket quan­tum tech­nolo­gies (QT), TOPTICA is the main sup­pli­er of laser sys­tems. In addi­tion, TOPTICA has start­ed research on and the devel­op­ment of QT sub­sys­tems and QT sys­tems to push aca­d­e­m­ic research as well as indus­tri­al real­iza­tion of QT appli­ca­tion sys­tems and instru­ments. TOPTICA’s R&D depart­ment con­sists at present of more than 65 peo­ple, many with a degree in physics or engi­neer­ing.

Enabling quan­tum net­works

TOPTICA employs spe­cial­ists in laser tech­nol­o­gy, optics, mechan­i­cal engi­neer­ing, elec­tri­cal engi­neer­ing and soft­ware engi­neer­ing and is there­fore opti­mal­ly pre­pared for the devel­op­ment of a nar­row-linewidth laser source for appli­ca­tion in NV-cen­ter-based quan­tum net­work nodes. In addi­tion, many employ­ees are appli­ca­tion experts in quan­tum tech­nolo­gies such as quan­tum com­mu­ni­ca­tion, quan­tum repeaters, non-clas­si­cal pho­ton sources, ion and atom cool­ing and trap­ping, opti­cal clocks and fre­quen­cy combs, and quan­tum metrol­o­gy.

The most rel­e­vant experts will con­tribute to con­cep­tu­al work on long-dis­tance phase-sta­ble quan­tum net­work links. This will guar­an­tee that TOPTICA’s tech­nol­o­gy devel­op­ment will meet all require­ments of the envi­sioned appli­ca­tions. TOPTICA has demon­strat­ed in the past how one can suc­cess­ful­ly trans­fer sci­en­tif­ic achieve­ments, e.g. exter­nal cav­i­ty diode laser for atom­ic spec­troscopy, into prod­ucts and is will­ing to share its expe­ri­ence with part­ners. This includes direct­ly busi­ness-relat­ed top­ics and out­reach and com­mu­ni­ca­tion strate­gies.
