Nto ua txoj kev ntawm titanium-doped sapphire siv lead ua laser rods

Titanium gemstone crystals Ti: Al2O3 (doping concentration 0.35 wt% Ti2O3), cov khoom siv lead ua blanks uas yog raws li cov txheej txheem ntws ntawm cov txheej txheem txheej txheem ntawm titanium gemstone siv lead ua laser pas nrig ntawm cov khoom tsim tam sim no tau qhia hauv daim duab 1. Cov kev npaj tshwj xeeb ntawm cov txheej txheem txheej txheem ntawm titanium gemstone siv lead ua laser pas nrig ntawm qhov kev tsim kho tam sim no yog raws li hauv qab no:

<1> Orientation txiav: titanium gemstone siv lead ua yog thawj taw qhia, thiab tom qab ntawd txiav mus rau hauv tetragonal kem-zoo li tus dawb paug los ntawm kev tawm ntawm kev ua haujlwm ntawm kwv yees li 0.4 mus rau 0.6 hli raws li qhov loj ntawm qhov ua tiav laser pas nrig.

<2>Kem ntxhib thiab zoo sib tsoo: Cov kem dawb paug yog hauv av rau hauv tetragonal lossis cylindrical cross-section nrog 120 ~ 180# silicon carbide lossis boron carbide abrasives ntawm lub tshuab sib tsoo ntxhib, nrog lub taper thiab tawm-ntawm-roundness yuam kev ntawm ± 0.01 hli

<3> Xaus ntsej muag ua tiav: titanium gemstone laser bar ob lub ntsej muag kawg ua tiav nrog W40, W20, W10 boron carbide sib tsoo lub ntsej muag kawg ntawm cov hlau disc. Nyob rau hauv txoj kev sib tsoo, yuav tsum tau them nyiaj mloog mus rau kev ntsuas lub verticality ntawm lub ntsej muag kawg.

<4> Tshuaj-mechanical polishing: tshuaj-mechanical polishing yog cov txheej txheem ntawm polishing crystals ntawm polishing ncoo nrog tee ntawm pre-formulated tshuaj etching tov. Polishing workpiece thiab polishing ncoo rau cov txheeb ze thiab kev sib txhuam, thaum nyob rau hauv kev tshawb fawb slurry muaj tshuaj etching tus neeg saib xyuas (hu ua polishing kua) kom tiav polishing nrog kev pab los ntawm.

<5> Acid etching: Cov titanium gemstone pas nrig tom qab polishing raws li tau piav qhia saum toj no yog muab tso rau hauv qhov sib xyaw ntawm H2SO4: H3PO4 = 3: 1 (v / v), ntawm qhov kub ntawm 100-400 ° C, thiab acid-etched rau 5 -30 feeb. Lub hom phiaj yog kom tshem tawm cov txheej txheem polishing ntawm qhov chaw ntawm lub laser bar uas tsim los ntawm cov neeg kho tshuab sub-surface puas, thiab tshem tawm ntau yam staining, thiaj li kom tau txais qib atomic ntawm du thiab tiaj tus, lattice kev ncaj ncees ntawm qhov huv si. .

<6> Kev Kho Hniav Hniav Hniav: Txhawm rau tshem tawm cov kev ntxhov siab thiab khawb ntxiv los ntawm cov txheej txheem ua ntej thiab tau txais ib qho chaw tiaj tus ntawm qib atomic, titanium gemstone pas nrig tom qab cov kua qaub etching yog ces yaug nrog dej deionised rau 5 feeb, thiab titanium gemstone pas nrig tau muab tso rau hauv ib puag ncig ntawm 1360 ± 20 ° C. ntawm qhov kub thiab txias ntawm 1 mus rau 3 teev nyob rau hauv ib qho chaw hydrogen, thiab raug kev kho cua sov saum npoo.
