Litšobotsi tsa bohlokoa tsa laser gain medium

Litšobotsi tsa bohlokoa tsa laser gain media ke life?

Laser gain medium, eo hape e tsejoang e le laser working substance, e bua ka sistimi ea lisebelisoa e sebelisetsoang ho fihlella phetoho ea palo ea batho le ho hlahisa mahlaseli a hlasimollang ho fihlela khanya ea khanya. Ke karolo ea mantlha ea laser, e jereng palo e kholo ea liathomo kapa limolek'hule, liathomo tsena kapa limolek'hule tse tlas'a ho tsosoa ha matla a kantle, li ka fetela sebakeng se thabileng, 'me ka mahlaseli a monate a lokolloa li-photons, kahoo li etsaleseli la laser. The laser gain medium e ka ba ntho e tiileng, e metsi, ea khase kapa ea semiconductor.
Ka li-lasers tse tiileng, mecha ea phatlalatso e atisang ho sebelisoa ke likristale tse nang le li-ion tsa lefatše tse sa tloaelehang kapa li-ion tsa tšepe tsa phetoho, tse kang Nd: YAG crystals, Nd: YVO4 crystals, joalo-joalo Ka li-lasers tsa metsi, li-dyes tsa organic li atisa ho sebelisoa e le mecha ea phatlalatso. Li-laser tsa khase li sebelisa khase e le mokhoa oa ho fumana chelete, joalo ka khase ea carbon dioxide ka har'a lilase tsa carbon dioxide, le helium le khase ea neon ho lilase tsa helium-neon.Lisebelisoa tsa laser tsa semiconductorsebelisa lisebelisoa tsa semiconductor e le mokhoa oa ho fumana chelete, joalo ka gallium arsenide (GaAs).
Litšobotsi tsa bohlokoa tsa laser gain medium li kenyelletsa:
Sebopeho sa boemo ba eneji: Liathomo kapa limolek'hule tse sebakeng sa phaello li hloka ho ba le sebopeho se loketseng sa matla e le ho fihlela phetoho ea baahi tlas'a ts'usumetso ea matla a kantle. Hangata sena se bolela hore phapang ea matla lipakeng tsa maemo a matla a holimo le a tlase a hloka ho ts'oana le matla a photon a bolelele bo itseng ba maqhubu.

Lintho tsa phetoho: Liathomo kapa limolek'hule tse libakeng tse thabileng li hloka ho ba le thepa e tsitsitseng ea phetoho e le hore li lokolle li-photon tse kopanetsoeng nakong ea mahlaseli a thabo. Sena se hloka hore mokhoa oa ho fumana chelete o be le ts'ebetso e phahameng ea quantum le tahlehelo e tlase.
Botsitso ba mocheso le matla a mochini: Lits'ebetsong tse sebetsang, sebaka sa ho fumana se hloka ho mamella leseli le phahameng la pompo ea matla le tlhahiso ea laser, kahoo e hloka ho ba le botsitso bo botle ba mocheso le matla a mochini.
Boleng ba Optical: Boleng ba optical ba mokhoa oa ho fumana chelete bo bohlokoa ho ts'ebetsong ea laser. E hloka ho ba le phetisetso ea khanya e phahameng le tahlehelo e tlase ea ho hasana ho netefatsa boleng le botsitso ba lebone la laser. Khetho ea laser gain medium e itšetlehile ka litlhoko tsa kopo ealaser, ho sebetsa wavelength, matla a tlhahiso le lintlha tse ling. Ka ho ntlafatsa thepa le sebopeho sa mokhoa oa ho fumana, ts'ebetso le katleho ea laser li ka ntlafatsoa le ho feta.
