Pamusoro pekugadzirisa nzira yetitanium-doped sapphire crystal laser rods

Titanium gemstone crystals Ti:Al2O3 (doping concentration 0.35 wt% Ti2O3), makristasi asina kuvharwa ayo ari maererano nemaitiro ekuyerera dhayagiramu yepamusoro pekugadzirisa nzira yetitanium gemstone gemstone crystal laser rod yezvino yakagadzirwa inoratidzwa muFig. Iwo chaiwo matanho ekugadzirira epamusoro pekugadzirisa nzira yetitanium gemstone crystal laser rod yeazvino yakagadzirwa ndeaya anotevera:

<1> Oriental kucheka: iyo titanium gemstone crystal inotanga kutariswa, yobva yachekwa kuita tetragonal column-shaped blank nekusiya mvumo yekugadzirisa inosvika 0.4 kusvika 0.6 mm zvinoenderana nehukuru hweraser rod yakapedzwa.

2 ±0.01mm.

<3> Pedzisa kugadziridzwa kwechiso: titanium gemstone laser bar two end face processing zvakatevedzana neW40, W20, W10 boron carbide inokuya kumagumo kumeso pane simbi disc. Mukuita kwekukuya, kutarisisa kunofanira kubhadharwa kuyera verticality yechiso chekupedzisira.

. Kupukuta workpiece uye polish pad yekufamba uye kukweshana, uku uri mukutsvagisa slurry ine chemical etching agent (inonzi polishing liquid) kupedzisa kupukuta nerubatsiro rwe.

<5> Acid etching: Iyo titanium gemstone tsvimbo mushure mekupenya sezvinotsanangurwa pamusoro apa inoiswa mumusanganiswa weH2SO4: H3PO4 = 3: 1 (v/v), pakupisa kwe100-400 ° C, uye acid-etched ye5. -30 maminitsi. Chinangwa ndechekubvisa kukwenenzverwa pamusoro peiyo laser bar inogadzirwa neiyo mechanic sub-surface kukuvara, uye kubvisa akasiyana mavara, kuitira kuti uwane iyo atomu nhanho yekutsvedzerera uye yakapfava, lattice kuperera kwenzvimbo yakachena. .

. uye titanium gemstone tsvimbo yakaiswa munzvimbo ye 1360 ± 20 ° C. pane imwe nguva tembiricha ye1 kusvika maawa 3 mumhepo ye hydrogen, uye pasi pekugadzirisa kupisa kwepamusoro.
