Txoj kev ua cov nto ntawm titanium-doped sapphire crystal laser rods

Cov pob zeb diamond titanium Ti:Al2O3 (doping concentration 0.35 wt% Ti2O3), cov pob zeb diamond uas yog raws li daim duab qhia txog kev ua haujlwm ntawm cov txheej txheem ua haujlwm ntawm cov pas nrig laser titanium gemstone crystal ntawm qhov kev tsim kho tshiab no tau qhia nyob rau hauv daim duab 1. Cov kauj ruam npaj tshwj xeeb ntawm cov txheej txheem ua haujlwm ntawm cov pas nrig laser titanium gemstone crystal ntawm qhov kev tsim kho tshiab no yog raws li nram no:

<1> Kev txiav kev taw qhia: thawj zaug txiav cov pob zeb diamond titanium, thiab tom qab ntawd txiav mus rau hauv ib lub duab plaub fab tetragonal los ntawm kev tso cai ua tiav li ntawm 0.4 txog 0.6 hli raws li qhov loj ntawm cov pas nrig laser tiav.

<2> Kev sib tsoo ntawm kem thiab sib tsoo zoo: Lub kem seem yog sib tsoo rau hauv tetragonal lossis cylindrical cross-section nrog 120 ~ 180 # silicon carbide lossis boron carbide abrasives ntawm lub tshuab sib tsoo ntxhib, nrog qhov taper thiab out-of-roundness yuam kev ntawm ± 0.01 hli.

<3> Kev ua tiav ntawm lub ntsej muag kawg: titanium gemstone laser bar ob lub ntsej muag kawg ua tiav nrog W40, W20, W10 boron carbide sib tsoo lub ntsej muag kawg ntawm lub disc hlau. Hauv cov txheej txheem sib tsoo, yuav tsum tau them sai sai rau kev ntsuas qhov ntsug ntawm lub ntsej muag kawg.

<4> Kev txhuam tshuaj lom neeg-mechanical: kev txhuam tshuaj lom neeg-mechanical yog cov txheej txheem ntawm kev txhuam cov siv lead ua rau ntawm lub ncoo txhuam nrog cov tee dej ntawm cov tshuaj etching uas tau npaj tseg ua ntej. Kev txhuam cov khoom siv thiab lub ncoo txhuam rau kev txav mus los thiab kev sib txhuam, thaum nyob hauv kev tshawb fawb slurry uas muaj cov neeg sawv cev etching tshuaj (hu ua kua txhuam) kom ua tiav kev txhuam nrog kev pab los ntawm.

<5> Acid etching: Cov pas nrig pob zeb titanium tom qab polishing raws li tau piav qhia saum toj no raug 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 tsim los ntawm kev puas tsuaj ntawm cov khoom siv kho tshuab, thiab kom tshem tawm ntau yam kev pleev xim, kom tau txais qib atomic ntawm du thiab tiaj tus, lattice kev ncaj ncees ntawm qhov chaw huv.

<6> KEV KHO KOM SOV NTAWM NTAU: Yuav kom tshem tawm cov kev ntxhov siab thiab khawb ntawm qhov chaw uas tshwm sim los ntawm cov txheej txheem ua ntej thiab tau txais qhov chaw tiaj tus ntawm qib atomic, cov pas nrig titanium gemstone tom qab acid etching tau yaug nrog dej deionised rau 5 feeb, thiab cov pas nrig titanium gemstone tau muab tso rau hauv ib puag ncig ntawm 1360 ± 20 ° C. ntawm qhov kub tas li ntawm 1 txog 3 teev hauv huab cua hydrogen, thiab raug kho kom sov ntawm qhov chaw.
