Kumvetsetsa Kusiyana Pakati pa Laser ndi Kuwala Wamba ndi Momwe Laser Amapangidwira

Ukadaulo wa Laser wasintha mafakitale osiyanasiyana, kuyambira opanga mpaka azachipatala. Koma nchiyani chimapangitsa kuwala kwa laser kukhala kosiyana ndi kuwala wamba? Nkhaniyi ikuwonetsa kusiyanitsa kwakukulu komanso njira yoyambira yopanga laser.

Kusiyana Pakati pa Laser ndi Kuwala Wamba

1. Monochromaticity: Kuwala kwa laser kuli ndi monochromaticity yabwino kwambiri, kutanthauza kuti imakhala ndi kutalika kwa mafunde amodzi okhala ndi mizere yopapatiza kwambiri. Mosiyana ndi zimenezi, kuwala wamba kumakhala kosakanikirana ndi mafunde angapo, zomwe zimapangitsa kuti pakhale mawonekedwe ambiri.

2. Kuwala ndi Kuchuluka kwa Mphamvu: Miyendo ya laser imakhala yowala kwambiri komanso kachulukidwe kamphamvu, zomwe zimawalola kuyika mphamvu zamphamvu mkati mwadera laling'ono. Kuwala wamba, ngakhale kumawoneka, kumakhala ndi kuwala kochepa kwambiri komanso kuyika mphamvu. Chifukwa cha mphamvu zambiri zotulutsa ma lasers, njira zoziziritsa zogwira mtima, monga zoziziritsa kukhosi zamafakitale, ndizofunikira kuti zisunge magwiridwe antchito komanso kupewa kutenthedwa.

3. Directionality: Miyendo ya laser imatha kufalikira m'njira yofananira kwambiri, ndikusunga mbali yaying'ono yosiyana. Izi zimapangitsa ma lasers kukhala abwino kwa ntchito zolondola. Kuwala wamba, kumbali ina, kumawonekera mbali zingapo, zomwe zimatsogolera kubalalitsidwa kwakukulu.

4. Kugwirizana: Kuwala kwa laser ndikogwirizana kwambiri, kutanthauza kuti mafunde ake amakhala ndi ma frequency, gawo, komanso momwe amafalikira. Kugwirizana kumeneku kumathandizira ntchito monga holography ndi kulumikizana kwa fiber optic. Kuwala wamba kulibe kugwirizanitsa kumeneku, ndipo mafunde ake amawonetsa magawo ndi mayendedwe.

Momwe Kuwala kwa Laser kumapangidwira

Njira yopangira laser imatengera mfundo yolimbikitsa kutulutsa. Zimaphatikizapo njira zotsatirazi:

1. Kulimbikitsa Mphamvu: Ma atomu kapena mamolekyu mu sing'anga ya laser (monga gasi, olimba, kapena semiconductor) amatenga mphamvu zakunja, kusintha ma elekitironi kupita kumalo apamwamba kwambiri.

2. Population Inversion: Mkhalidwe umatheka pomwe tinthu tambiri timakhala mu chisangalalo kuposa momwe mphamvu yocheperako imakhalira, ndikupanga kuchuluka kwa anthu - chofunikira kwambiri pakuchitapo kanthu kwa laser.

3. Stimulated Emission: Pamene atomu yokondwa ikumana ndi chithunzi chobwera cha utali winawake wa kutalika kwake, imatulutsa chithunzi chofanana, kukulitsa kuwala.

4. Optical Resonance ndi Amplification: Mafotoni otulutsidwa amawonekera mkati mwa chowunikira chowunikira (magalasi), kukulitsa mosalekeza pomwe mafotoni ambiri amakokedwa.

5. Kutulutsa kwa Laser Beam: Mphamvu ikafika pachimake chovuta, mtengo wolumikizana, wolunjika kwambiri wa laser umatulutsidwa kudzera pagalasi lowunikira pang'ono, lokonzekera kugwiritsidwa ntchito. Monga lasers ntchito pa kutentha kwambiri, kuphatikiza ndi mafakitale chiller  imathandizira kuwongolera kutentha, kuwonetsetsa kuti laser imagwira ntchito mosasinthasintha komanso kuwonjezera moyo wa zida.

Pomaliza, kuwala kwa laser kumasiyanitsidwa ndi kuwala wamba chifukwa cha mawonekedwe ake apadera: monochromaticity, kachulukidwe kamphamvu kwambiri, kuwongolera bwino, komanso kulumikizana. Njira yeniyeni yopangira laser imathandizira kuti igwiritsidwe ntchito kwambiri m'magawo apamwamba kwambiri monga kukonza mafakitale, opaleshoni yachipatala, ndi kulumikizana kwa kuwala. Kuti muwongolere bwino makina a laser komanso moyo wautali, kugwiritsa ntchito chotsitsa madzi odalirika ndi chinthu chofunikira kwambiri pakuwongolera kukhazikika kwamafuta.
