Titanium Sapphire Laser Muaj Zauv

Titanium doped sapphire (Ti3 +: Al2O3) yog siv rau kev lasers thiab cov femtosecond solid-state lasers.Nws yog thawj zaug siv los ua nce nruab nrab hauv 1986, thiab txog tam sim no, nws tseem yog qhov khoom zoo tshaj plaws rau ultrashort pulse cim. Lub substrate-sapphire muaj lub cev zoo thiab kho qhov muag. Siab thermal conductivity thiab zoo alleviating thermal teebmeem muab cov usability rau siab zog laser.

Kev piav qhia

Ti: Sapphire (Titanium doped Sapphire, Al 2 O 3 : Ti 3+ ) muaj ntau yam ntawm cov pa tawm ntawm 660 txog 1050 nm, uas muaj ntau yam kev siv thiab muaj peev xwm siv tau, xws li cov khoom siv nrawm rau tuning, xauv oscillators, chirp-pulse amplifiers, nyias disk oscillators / amplifiers thiab lidars. Tsis tas li ntawd, lub hnab nqus ntawm Ti: Sapphire yog nruab nrab ntawm 490 nm, ib qho ntawm 400 rau 650 nm, uas ua rau nws tsim kom muaj cov twj siv ntau yam ntawm cov lasers, piv txwv li, argon ion, zaus doubled Nd: YAG (Nd: YLF) , thiab tooj liab vapor lasers. Vim tias 3.2 μl fluorescence lub neej, Ti: Sapphire crystals yuav zoo tau pumped los ntawm cov teeb nyob rau hauv cov hluav taws xob tshuab hluav taws xob.

Yuav kom tau zoo ntawm Ti: Sapphire crystals, Ti 3+ doping concentration yuav tsum tau khaws cia haum tsawg (piv txwv li 0.15% lossis 0.25%). Vim li no, cov twj tso kua mis tsuas yog siv cov qwj siv ntau ntawm cov millimeters, uas nrog lub taub me me me me (rau cov twj siv twj tso kua mis siab) txhais tau hais tias lub teeb pom kev zoo siab yuav tsum yog. Zoo hmoo, Sapphire kuj muaj kev thermal conductivity zoo, alleviating thermal teebmeem txawm rau siab laser powers.
