ʻO ke ʻano hana ʻili o ka titanium-doped sapphire crystal laser rods

Titanium gemstone crystals Ti:Al2O3 (doping concentrate 0.35 wt% Ti2O3), o na blank blanks e like me ke kaʻina hana kahe ana o ke kaʻina hana ili o ka titanium gemstone crystal laser rod o ka mea i hana ʻia e hōʻike ʻia ma Fig.

<1> ʻOki ʻana: ʻo ka titanium gemstone crystal i hoʻonohonoho mua ʻia, a laila ʻoki ʻia i loko o kahi kolamu tetragonal me ka waiho ʻana i kahi alana hana ma kahi o 0.4 a 0.6 mm e like me ka nui o ke koʻokoʻo laser paʻa.

<2> ʻO ke kolamu ʻōniʻoniʻo a me ka wili maikaʻi: Hoʻopili ʻia ke kolamu blank i kahi ʻāpana tetragonal a cylindrical me ka 120 ~ 180 # silicon carbide a i ʻole boron carbide abrasives ma luna o ka mīkini wili ʻala, me kahi hapa taper a out-of-roundness o ± 0.01mm.

<3> Hoʻopau i ka hana ʻana i ka maka: titanium gemstone laser bar ʻelua hopena maka e hoʻoheheʻe ʻia me ka W40, W20, W10 boron carbide wili i ka maka hope ma ka disc kila. I ke kaʻina wili, pono e nānā i ke ana ʻana i ka verticality o ka maka hope.

<4> Kemikini-mechanical polishing: kemika-mechanical polishing ke kaʻina hana o ka poʻi kristal ma ka poli hoʻopololei me nā kulu o ka mea i hoʻomākaukau muaʻia etching etching solution. ʻO ka mea hana polishing a me ka pad polishing no ka neʻe ʻana a me ka friction, ʻoiai i loko o ka slurry noiʻi i loaʻa i ka mea etching kemika (kapa ʻia ka wai polishing) e hoʻopau i ka polishing me ke kōkua o.

<5> Acid etching: Hoʻokomo ʻia nā koʻokoʻo titanium gemstone ma hope o ka hoʻomaʻamaʻa ʻana e like me ka mea i hōʻike ʻia ma luna nei i loko o ka hui ʻana o H2SO4:H3PO4 = 3:1 (v/v), ma kahi mahana o 100-400 ° C, a hoʻopaʻa ʻia i ka waikawa no 5-30 mau minuke. ʻO ke kumu o ka wehe ʻana i ke kaʻina polishing ma luna o ka ʻili o ka pahu laser i hana ʻia e ka pōʻino lalo o ka mechanical, a e wehe i nā ʻano ʻano like ʻole, i mea e loaʻa ai ka pae atomika o ka maʻemaʻe a me ka palahalaha, ka lattice pono o ka ʻili maʻemaʻe.

<6> KA HOʻOPIʻI HEAT LU: I mea e hoʻopau hou ai i nā koʻikoʻi o ka ʻili a me nā ʻōpala i hana ʻia ma muli o ke kaʻina hana ma mua a loaʻa kahi ʻili palahalaha ma ka pae atomic, ua holoi ʻia ke koʻokoʻo titanium gemstone ma hope o ka etching acid me ka wai deionised no 5 mau minuke, a ua kau ʻia ke koʻokoʻo titanium gemstone i loko o kahi kaiapuni o 1360 ± 20 ° C. i ka lapaʻau ʻana mehana.
