Indlela yokucubungula engaphezulu ye-titanium-doped sapphire crystal laser rods

Amakristalu etshe eliyigugu le-Titanium Ti:Al2O3 (i-doping concentration 0.35 wt% Ti2O3), izikhala zekristalu ezihambisana nomdwebo wokugeleza kwenqubo yendlela yokucubungula indawo yetshe le-titanium gemstone crystal rod yokusungulwa kwamanje kuboniswa kuFig. 1. Izinyathelo ezithile zokulungiselela zendlela yokucubungula indawo ye-titanium gemstone crystal rod yokusungulwa kwamanje imi kanje:

1

<2>Ikholomu igaya kahle futhi igaya kahle: Ikholomu engenalutho igaywa ibe yisiqephu esiphambanayo esine-tetragonal noma isilinda esinama-silicon carbide angu-120~180# noma ama-boron carbide abrasives emshinini wokugaya omahhadlahhadla, onephutha le-taper nelingaphandle kwe-roundness ±0.01mm.

<3> Qeda ukucutshungulwa kobuso: Ibha ye-titanium gemstone laser bar isiphetho sobuso sicutshungulwa ngokulandelana nge-W40, W20, W10 boron carbide ekupheleni kobuso kudiski yensimbi. Enkambweni yokugaya, ukunakwa kufanele kukhokhwe ekulinganiseni ukuma kobuso bokuphela.

<4> Ukupholisha ngamakhemikhali: ukupholishwa ngamakhemikhali kuyinqubo yokupholisha amakristalu ephedi lokupholisha ngamaconsi esixazululo esakhiwe ngaphambili samakhemikhali. Ucwecwe lokusebenza lokupholisha kanye nephedi yokupholisha ukuze kuhambisane nokunyakaza nokungqubuzana, kuyilapho ku-slurry yocwaningo equkethe i-chemical etching agent (ebizwa ngokuthi uketshezi lokupholisha) ukuze kuqedelwe ukupholishwa ngosizo lwe.

<5> Ukufakwa kwe-Acid: Izinti zetshe eliyigugu le-titanium ngemva kokupholishwa njengoba kuchazwe ngenhla zifakwa engxubeni ye-H2SO4:H3PO4 = 3:1 (v/v), ezingeni lokushisa elingu-100-400°C, kanye ne-asidi efakwe ku-5 - imizuzu engama-30. Inhloso ukususa inqubo yokupholisha ebusweni bebha ye-laser ekhiqizwe umonakalo owenziwe ngomshini ongaphansi komhlaba, kanye nokususa amabala ahlukahlukene, ukuze kutholwe izinga le-athomu lokubushelelezi neliyisicaba, ubuqotho be-lattice yendawo ehlanzekile. .

<6> UKWELASHWA OKUSHISA EMHLABENI: Ukuze kuqhutshekwe kuqedwe ukucindezelwa kwendawo nokuklwebheka okukhiqizwa ngenxa yenqubo eyandulele futhi kutholwe indawo eyisicaba ezingeni le-athomu, intonga yetshe eliyigugu le-titanium ngemva kokufakwa kwe-asidi yabe ihlanjululwa ngamanzi angcolile imizuzu emi-5, futhi induku yetshe eliyigugu le-titanium yabekwa endaweni engu-1360 ± 20° C. ekushiseni okungaguquki kwe-1 kuya ku-3 amahora emkhathini we-hydrogen, futhi ingaphansi kokwelashwa kokushisa okungaphezulu.
