Kumenyekanisha "Ubugingo" bwa lasers zo mu rwego rwo hejuru

Ihuriro ry'ingenzilaser ya leta ikomeyeibikoresho

Ishingiro rya laser iyo ari yo yose ni ikintu gikora cya laser, n'ikintu gikora cya solid-statelasermu by’ukuri ni ikomeye. Ibyuma byinshi bya laser bigizwe na matrices za kristu na atome cyangwa iyoni za doped hamwe n’imikorere ya laser, mu gihe matrices z’ibirahuri zitagira imiterere ihagije. Iterambere rigezweho mu ikoranabuhanga ryo gutegura ceramic ryitezweho kwagura cyane uburyo bwo gukoresha ibikoresho bya laser bihendutse kandi byiza, bishobora gukorwa mu bunini buruta ubw’ibikoresho bya kristu.

Ibikoresho bya laser bikoreshwa cyane muri core

Rubi: Imiterere yayo ya shimi ni aluminium oxyde ifite chromium (Cr:Al₂O₃). Rubi z'ubukorano zifite imiterere ya shimi isa na rubi z'agaciro, ariko zifite ubuziranenge n'ubwiza bwo hejuru. Zisa n'umutuku w'ibara ry'umutuku kandi zifite uburebure bwa laser bwa nanometero 694.3.

2. Garnet ya aluminiyumu ya yttrium ifite Neodymium (Nd:YAG): Kristale y’ubukorano, ifite uburebure bwa laser bwa nanometero 1064, ikomoka ku rumuri rwa hafi ya infrared kandi ntigaragara na gato kandi ntiri mu mutekano ku maso. Nd:YAG ni yo material ya laser ikoreshwa cyane muri iki gihe, irenze kure rubi. Impamvu nyamukuru ni uko urwego rwayo rwa laser ruri hasi, kandi ishobora kugera ku ngufu nyinshi zisohoka hakoreshejwe ingufu zimwe zinjira.

3. Yttrium vanadate ya Neodymium-doped (Nd:YVO₄) Ikunze kwitwa "vanadate", yabaye ibikoresho bikunzwe cyane kuri lasers solid-state lasers zifite ingufu nkeya kugeza kuri za watts nyinshi (kugeza kuri watts nyinshi) bitewe n'uko zifite ingufu nyinshi zituma zisohoka, urwego rwa laser ruciriritse hamwe n'imiterere y'umusaruro wa polarized. Ubunini bw'uburebure bw'umurambararo ni nanometero 1064 na nanometero 1340, kandi nyuma yo gukuba kabiri inshuro nyinshi, ishobora gusohora lasers zifite ubunini bw'umurambararo bwa nanometero 532 na nanometero 670.

4. Ikirahure cya Neodymium (Nd: Ikirahure): Gikoresheje ikirahure kidahinduka nk'umubumbe, imiterere yacyo ya lazeri isa n'iya Nd: YAG. Ingorane yacyo nyamukuru ni uko ubushyuhe bwacyo butwara ubushyuhe buri hasi, 1/10 gusa cy'icya kristu, bigatuma bigorana gukonja mu bikorwa bifite ingufu nyinshi. Ariko, inyungu yacyo iri mu kuba gishobora gukorwamo icyuma cya lazeri gifite umurambararo urenze metero imwe, kikagenzura neza ubucucike bw'ingufu, cyirinda kwangiza ibice by'urumuri mu rwego rwa kilojoule.laser ikoresha pulse, kandi ikaba ifite igiciro gito cyane.

Ibindi bikoresho by'ingenzi bya laser bya solid-state, ibikoresho bya erbium-doped: harimo garnet ya aluminiyumu ya yttrium (Er:YAG, uburebure bw'umuvuduko wa 2940 nanometers) n'ikirahure cya erbium-doped (Er:Ikirahure, uburebure bw'umuvuduko wa 1540 nanometers). Ibikoresho bya Holmium doped: birimo holmium doped yttrium aluminum garnet (Ho:YAG), holmium doped lithium yttrium fluoride (Ho:YLF), na holmium doped Glass (Ho:ikirahure, uburebure bw'umuvuduko wa 2000 kugeza 2100 nanometers). Ibikoresho bya Thulium-doped: harimo thulium-doped yttrium aluminum garnet (Tm:YAG), lutetium aluminum garnet (Tm:LuAG), na thulium-holmium co-doped lithium yttrium fluoride (Tm,Ho:YLF, uburebure bw'umusaruro kuva kuri nanometero 2000 kugeza 2030). Ibikoresho bya Ytterbium-doped: nka ytterbium-doped potassium gadolinium tungstate (Yb:KGW, uburebure bw'umusaruro kuva kuri nanometero 1025 kugeza 1045). Alexandrite (uburebure bw'umusaruro kuva kuri nanometero 655 kugeza 815). Safiro ya Titanium-doped (Ti:Sapphire, uburebure bw'umusaruro kuva kuri nanometero 840 kugeza 1100)
