Indlela yokucubungula umphezulu we-titanium-doped sapphire crystal laser rods

Iikristale ze-Titanium gemstone Ti: Al2O3 (i-doping concentration 0.35 wt% Ti2O3), i-crystal blanks ehambelana nenkqubo yokuhamba kwedayagram yendlela yokucubungula umphezulu we-titanium gemstone crystal rod ye-laser yangoku iboniswe kwi-Fig. 1. Amanyathelo athile okulungiselela indlela yokulungiswa komphezulu we-titanium gemstone crystal rod yoyilo lwangoku lulandelayo:

<1> Ukusika i-Orientation: i-titanium gemstone crystal iqala ukuqhelaniswa, kwaye emva koko inqunyulwe ibe yi-tetragonal column-shaped blank ngokushiya isibonelelo sokucubungula malunga ne-0.4 ukuya kwi-0.6 mm ngokuhambelana nobukhulu bentonga ye-laser egqityiweyo.

<2>Ikholamu erhabaxa kunye nokusila kakuhle: Uluhlu olungenanto lugutyungelwa kwi-tetragonal okanye icylindrical cross-section kunye ne-120 ~ 180# yesilicon carbide okanye i-boron carbide abrasives kumatshini wokusila orhabaxa, onetaper kunye nempazamo engaphandle kokungqukuva. ±0.01mm.

<3> Ukuphelisa ukucwangciswa kobuso: i-titanium gemstone laser bar ezimbini zokuphela kobuso ngokulandelelana kunye ne-W40, W20, i-W10 ye-boron carbide yokugaya isiphelo sobuso kwi-disc yensimbi. Kwinkqubo yokugaya, ingqalelo kufuneka ihlawulwe ekulinganiseni ukuqina kobuso bokuphela.

<4> I-Chemical-mechanical polishing: i-chemical-mechanical polishing yinkqubo yokupholisa iikristale kwi-pad yokupholisa kunye namaconsi esisombululo se-chemical etching pre-formulated. Isixhobo sokusebenza sokumenyeza kunye nepad yokupolisha ukwenzela intshukumo ehambelanayo kunye nokukhuhlana, ngelixa kwi-slurry yophando equlethe i-agent etching agent (ebizwa ngokuba yi-polish liquid) ukugqiba ukugulisa ngoncedo lwe.

<5> I-Acid etching: Iintsimbi ze-titanium gemstone emva kokupholisa njengoko kuchazwe ngasentla zifakwe kumxube we-H2SO4: H3PO4 = 3: 1 (v / v), kwiqondo lokushisa le-100-400 ° C, kunye ne-acid-etched for 5 -30 imizuzu. Injongo kukususa inkqubo yokupolisha kumphezulu we-laser bar oveliswe ngumonakalo ongaphantsi komphezulu womatshini, kunye nokususa iintlobo ezahlukeneyo zokungcola, ukuze ufumane inqanaba le-athomu eligudileyo kunye nelicaba, ingqibelelo yelatisi yendawo ecocekileyo. .

<6> UKUNYANGWA OKUSHISA EMHLABENI: Ukwenzela ukuphelisa ngakumbi uxinzelelo lomphezulu kunye nemikrwelo eyenziwe ngenxa yenkqubo yangaphambili kunye nokufumana indawo ethe tyaba kwinqanaba le-athomu, intonga ye-titanium gemstone emva kokufakwa kwe-asidi yahlanjululwa ngamanzi adityanisiweyo imizuzu emi-5, kwaye intonga ye-titanium gemstone ibekwe kwindawo ye-1360 ± 20 ° C. kwiqondo lokushisa elingaguqukiyo le-1 ukuya kwiiyure ze-3 kwi-atmosphere ye-hydrogen, kwaye iphantsi konyango lobushushu bomhlaba.
