Daim ntawv thov ntawm Neodymium Ion Concentration Gradient YAG Crystal hauv End-Pumped Laser Technology

Txoj kev loj hlob sai ntawm laser technology yog inseparable los ntawm kev txhim kho loj ntawm semiconductor lasers, dag siv lead ua cov ntaub ntawv thiab cov khoom siv. Tam sim no, lub teb ntawm semiconductor thiab solid-state laser tshuab yog vam meej. Txhawm rau kom nkag siab ntxiv txog kev tshawb fawb txog kev tshawb fawb thiab kev tiv thaiv kev ruaj ntseg hauv teb chaws xav tau ntawm high-power semiconductor thiab solid-state laser thev naus laus zis, thiab txhawb kev sib pauv kev kawm nyob rau hauv sab sauv thiab qis qis ntawm laser technology, Tuam Tshoj Society of Optical Engineering yuav tuav "Advanced Semiconductor, Solid-State Laser Technology thiab Application Exchange Conference" nyob rau hauv 2024 los ua kev sib pauv ntawm cov ntaub ntawv tseem ceeb, kev vam meej thiab kev loj hlob ntawm lub cev. Cov kev cia siab hais txog semiconductors thiab solid-state lasers.

Ntawm lub rooj sib tham no, peb lub tuam txhab tus thawj tswj hwm, Zhang Jianjun, tau tshaj tawm txog daim ntawv thov ntawmNeodymium ion concentrationgradientYAG crystalnyob rau hauv kawg-pump laser technology.Solid-state lasers yog feem ntau optically pumped, thiab muaj ob lub ntsiab ntawm kev siv txoj kev: teeb twj tso kua mis thiab diode twj tso kua mis. Diode-pumped solid-state lasers (DPSSL) muaj qhov zoo ntawm kev ua haujlwm siab, siab beam zoo, zoo stability, compact qauv, thiab lub neej ntev. Diode twj tso kua mis yog siv nyob rau hauv Nd:YAG lasers nyob rau hauv ob hom twj tso kua mis: sab twj tso kua mis (xa mus rau sab twj tso kua mis) thiab kawg twj tso kua mis (xa mus rau qhov kawg twj tso kua mis).

Piv nrog rau cov twj tso kua mis thiab semiconductor sab twj tso kua mis, semiconductor kawg twj tso kua mis yooj yim dua kom ua tiav hom kev sib piv ntawm lub teeb ci thiab oscillating lub teeb nyob rau hauv lub laser kab noj hniav. Ntxiv mus, tsom rau lub twj tso kua mis beam rau qhov loj me me dua li cov pas nrig laser tuaj yeem txwv tus naj npawb ntawm cov qauv hauv kab noj hniav thiab txhim kho cov nqaj zoo. Nyob rau tib lub sijhawm, nws muaj qhov zoo ntawm cov qauv compact, qis laser pib, thiab kev ua haujlwm siab. Cov kev tshawb fawb tau pom tias qhov kawg ntawm kev siv tam sim no yog txoj kev siv tau zoo tshaj plaws.
