Laser crystals thiab lawv cov khoom yog cov ntaub ntawv tseem ceeb rau kev lag luam optoelectronics. Nws kuj yog ib qho tseem ceeb ntawm cov khoom siv hluav taws xob lasers los tsim lub teeb laser. Raws li qhov zoo ntawm cov khoom siv kho qhov muag zoo, cov khoom siv kho qhov muag zoo, lub cev muaj zog thiab tshuaj lom neeg ruaj khov, thiab cov thermal conductivity zoo, laser muaju tseem yog cov khoom siv nrov rau cov khoom lag luam laser. Yog li ntawd, nws yog dav siv nyob rau hauv industrial, kho mob, kev tshawb fawb, kev sib txuas lus thiab tub rog industries. Xws li laser ntau, laser lub hom phiaj qhia, laser nrhiav, laser npav, laser txiav ua (xws li txiav, drilling, vuam thiab engraving, thiab lwm yam), laser kho mob, thiab laser kev zoo nkauj, thiab lwm yam.
Laser hais txog kev siv feem ntau ntawm cov khoom siv hauv cov khoom ua haujlwm hauv lub xeev zoo siab, thiab kev siv lub teeb sab nraud induction ua kom tag nrho cov khoom hauv lub xeev zoo siab ua tiav cov hluav taws xob txhawb nqa tib lub sijhawm, ua kom muaj lub zog loj. Lasers muaj kev taw qhia zoo heev, monochromaticity thiab coherence, thiab nyob rau hauv kev pom ntawm cov yam ntxwv, nws yog dav siv nyob rau hauv txhua yam ntawm lub neej.
Lub laser siv lead ua muaj ob qhov chaw, ib qho yog lub tshuab ua kom muaj zog ion li "luminescence center", thiab lwm qhov yog lub party siv lead ua li "carrier" ntawm lub tshuab txais ion. Qhov tseem ceeb tshaj ntawm cov tswv tsev muaju yog cov oxide crystals. Cov khoom siv lead ua no muaj qhov tshwj xeeb zoo xws li qhov siab melting point, siab hardness thiab zoo thermal conductivity. Ntawm lawv, ruby thiab YAG tau siv dav, vim tias lawv cov lattice tsis xws luag tuaj yeem nqus pom lub teeb nyob rau hauv ib qho spectral ntau yam los nthuav tawm qee yam xim, yog li paub txog tunable laser oscillation.
Ntxiv nrog rau cov tshuaj siv lead ua lasers, cov khoom siv laser kuj tseem tsim nyob rau hauv ob qho kev qhia: ultra-loj thiab ultra-me. Ultra-loj siv lead ua lasers yog siv nyob rau hauv laser nuclear fusion, laser isotope sib cais, laser txiav thiab lwm yam lag luam. Ultra-me me siv lead ua lasers tsuas yog xa mus rau semiconductor lasers. Nws muaj qhov zoo ntawm kev siv lub zog siab, me me thermal load ntawm cov siv lead ua, ruaj khov laser tso zis, lub neej ntev, thiab me me ntawm laser, yog li nws muaj kev loj hlob zoo hauv kev siv tshwj xeeb.
