Laser Yunguka Hagati Niki?
Laser yunguka ibikoresho ni ibikoresho byongerera urumuri imyuka ihumanya ikirere. Iyo atome cyangwa molekile ziciriritse zishimiwe kurwego rwo hejuru rwingufu, zirashobora gusohora fotone yuburebure bwumurongo runaka mugihe ugarutse kumbaraga nkeya. Iyi nzira yongerera urumuri kunyura hagati, arirwo rufatiro rwo gukora laser.

Nibisanzwe Byunguka Hagati?
Inyungu iciriritse irashobora gutandukana, harimoimyuka, amazi (amarangi), ibinini.Inzira zikomeye, kurugero, akenshi ukoreshe kristu nka Nd: YAG (Neodymium-yuzuye Yttrium Aluminium Garnet) cyangwa ibirahuri byometse kubintu bidasanzwe-isi. Lazeri yo gusiga irangi ikoresha amarangi kama yashonga mumashanyarazi, kandi lazeri ikoresha gaze cyangwa imvange ya gaze.
Inkoni ya Laser (uhereye ibumoso ugana iburyo): Ruby, Alexandrite, Er: YAG, Nd: YAG
Itandukaniro riri hagati ya Nd (Neodymium), Er (Erbium), na Yb (Ytterbium) nkinyungu zunguka
cyane cyane bifitanye isano nuburebure bwabyo, uburyo bwo guhererekanya ingufu, hamwe nibisabwa, cyane cyane murwego rwibikoresho bya laser.
Uburebure bw’imyuka ihumanya ikirere:
- Er: Ubusanzwe Erbium isohora 1.55 µm, iri mukarere keza amaso kandi ifite akamaro kanini mubikorwa byitumanaho kubera gutakaza gake muri fibre optique (Gong et al., 2016).
- Yb: Ytterbium ikunze gusohora hafi 1.0 kugeza kuri 1,1 µm, bigatuma ikwirakwira muburyo butandukanye bwa porogaramu, harimo lazeri zifite ingufu nyinshi na amplifier. Yb ikoreshwa kenshi nka sensibilisateur ya Er kugirango yongere imikorere yibikoresho bya Er-doped mu kohereza ingufu muri Yb muri Er.
- Nd: Ibikoresho bya Neodymium bisanzwe bisohoka hafi 1.06 µm. Nd: YAG, kurugero, izwiho gukora neza kandi ikoreshwa cyane haba mu nganda n’ubuvuzi (Y. Chang et al., 2009).
Uburyo bwo kohereza ingufu:
- Er na Yb Co-doping: Gukora doping ya Er na Yb muburyo bwakiriye ni ingirakamaro mukuzamura imyuka ihumanya 1.5-1,6 µm. Yb ikora nka sensibilisateur ikora kuri Er ikurura urumuri rwa pompe no kohereza ingufu muri Er ion, biganisha ku byuka bihumanya mu itsinda ryitumanaho. Ihererekanyabubasha ningirakamaro mubikorwa bya Er-doped fibre amplifier (EDFA) (DK Vysokikh et al., 2023).
- Nd: Nd ntabwo isanzwe ikenera sensibilisateur nka Yb muri sisitemu ya Er-doped. Imikorere ya Nd ikomoka ku kwinjiza mu buryo butaziguye urumuri rwa pompe no gusohora nyuma, bigatuma lazeri yunguka kandi ikora neza.
Porogaramu:
- Er:Byibanze bikoreshwa mubitumanaho kubera ko bisohoka kuri 1.55 µm, bihurirana nidirishya ryigihombo cya silika optique ya fibre optique. Er-doped yunguka uburyo ningirakamaro kuri optique ya optique na laseri muri sisitemu ndende ya fibre optique.
- Yb:Akenshi ikoreshwa mububasha bukomeye cyane bitewe nuburyo bworoshye bwa elegitoronike butuma pompe ikora neza kandi ikabyara ingufu nyinshi. Ibikoresho bya Yb-bikoreshwa nabyo mukuzamura imikorere ya sisitemu ya Er-doped.
- Nd: Bikwiranye nuburyo butandukanye bwo gusaba, kuva gukata inganda no gusudira kugeza lazeri yubuvuzi. Nd: Lazeri ya YAG ihabwa agaciro cyane kubikorwa byayo, imbaraga, hamwe na byinshi.
Kuki twahisemo Nd: YAG nkinyungu zunguka muri laser ya DPSS
Laser ya DPSS ni ubwoko bwa lazeri ikoresha uburyo bukomeye bwo kubona inyungu (nka Nd: YAG) yavomwe na semiconductor laser diode. Iri koranabuhanga ryemerera laseri zoroheje, zikora neza zishobora gutanga ibiti byo murwego rwohejuru muburyo bugaragara-kuri-infragre. Kubiganiro birambuye, urashobora gutekereza gushakisha ukoresheje ububiko bwubumenyi buzwi cyangwa abamamaji kugirango basuzume byuzuye kubijyanye na tekinoroji ya DPSS.
[Ibicuruzwa bifitanye isano:Diode-pompe ikomeye-ya laser]
Nd: YAG ikoreshwa nkinyungu zunguka muri semiconductor-pompe laser modules kubwimpamvu nyinshi, nkuko byagaragajwe nubushakashatsi butandukanye:
1.Ubushobozi Bukuru hamwe nimbaraga zisohoka. Ibi birerekana imikorere ihanitse hamwe nubushobozi bwo gusohora ingufu nyinshi za Nd: YAG laseri iyo ivomwe na diode (Lera et al., 2016).
2.Imikorere ihindagurika kandi yizewe: Nd. Ibi birerekana Nd: Guhindura kwa YAG no kwizerwa nkinyungu zunguka mubikorwa bitandukanye bya lazeri (Zhang et al., 2013).
3. Kuramba no kumera neza. Ubushakashatsi bwatangaje ko ibikorwa byongerewe amasasu arenga 4.8 x 10 ^ 9 nta byangiritse byangiza, bikomeza ubwiza buhebuje (Coyle et al., 2004).
4.Ibikorwa Byinshi Bikomeza Gukomeza-Umuhengeri:Ubushakashatsi bwerekanye imikorere ikora neza-ikomeza (CW) imikorere ya Nd: YAG laseri, ikagaragaza imbaraga zayo nkinyungu zunguka muri sisitemu ya lazeri. Ibi bikubiyemo kugera ku buryo buhanitse bwo guhindura ibintu neza no guhanuka, bikomeza kwemeza ko Nd: YAG ikoreshwa neza na lazeri (Zhu et al., 2013).
Ihuriro ryimikorere ihanitse, imbaraga zisohoka, imikorere ihindagurika, kwizerwa, kuramba, hamwe nubwiza buhebuje butuma Nd: YAG yunguka uburyo bworoshye muri semiconductor-pompe laser modules kumurongo mugari wa porogaramu.
