Nd: YLF - Nd-doped Lithium Yttrium Fluoride

Lus piav qhia luv luv:

Nd:YLF siv lead ua yog ib qho tseem ceeb heev siv lead ua laser ua haujlwm tom qab Nd:YAG. YLF siv lead ua matrix muaj luv luv UV absorption cut-off wavelength, ntau lub teeb kis tau tus mob, qhov kub tsis zoo coefficient ntawm refractive index, thiab cov nyhuv thermal me me. Lub cell yog tsim rau doping ntau yam tsawg lub ntiaj teb ions, thiab muaj peev xwm paub laser oscillation ntawm ib tug loj tus naj npawb ntawm wavelengths, tshwj xeeb tshaj yog ultraviolet wavelengths. Nd: YLF siv lead ua muaj qhov nqus dav dav, lub neej ntev fluorescence, thiab cov zis polarization, haum rau LD siv, thiab tau siv dav hauv cov tshuab nqus thiab nruam lasers hauv ntau hom kev ua haujlwm, tshwj xeeb tshaj yog nyob rau hauv ib hom tso zis, Q-hloov ultrashort mem tes lasers. Nd: YLF siv lead ua p-polarized 1.053mm laser thiab phosphate neodymium iav 1.054mm laser wavelength match, yog li nws yog ib qho khoom siv ua haujlwm zoo tshaj plaws rau oscillator ntawm neodymium iav laser nuclear kev puas tsuaj.

Nta

Nd: YLF siv lead ua, tseem hu ua Nd-doped lithium yttrium fluoride, yog lithium yttrium fluoride siv lead ua uas tsim 1047nm thiab 1053nm lasers. Lub ntsiab zoo ntawm Nd: YLF siv lead ua yog: super loj fluorescent linewidth, tsis tshua muaj thermal lens nyhuv, txuas ntxiv laser daim ntawv thov txo qis excitation lub teeb pib, ntuj polarization, thiab lwm yam. Yog li ntawd, Nd: YLF siv lead ua, neodymium-doped lithium yttrium fluoride yog ib qho zoo tagnrho laser siv lead ua cov khoom siv txuas ntxiv laser thiab hom-xauv laser. Lub Nd: YLF siv lead ua peb muab, Nd-doped lithium yttrium fluoride zus los ntawm Czochralsky txoj kev, muaj peev xwm muab Nd: YLF siv lead ua pas nrig los yog Nd: YLF siv lead ua phaj nrog txawv doping concentration.
