Hunhu hukuru hwe laser gain medium

Ndezvipi zvinhu zvikuru zvine chekuita ne laser gain media?

Laser gain medium, inozivikanwawo se laser working substance, inoreva sisitimu yezvinhu zvinoshandiswa kuunza particle population inversion uye kugadzira stimulated radiation kuti iwane light amplification. Ndiyo chikamu chikuru che laser, ichitakura huwandu hwakawanda hwemaatomu kana mamorekuru, maatomu aya kana mamorekuru ari pasi pe excitation ye external energy, anogona kuchinja kuenda ku excited state, uye kuburikidza ne excited radiation inoburitsa ma photons, nokudaro ichiumba achiedza chelaser. Chinhu chinopa laser gain medium chinogona kuva chinhu chakasimba, chemvura, chegasi kana che semiconductor.
Muma lasers e solid-state, gain media inowanzoshandiswa ma crystals akaiswa ma rare earth ions kana ma transition metal ions, akadai se Nd:YAG crystals, Nd:YVO4 crystals, nezvimwewo. Mu liquid lasers, organic dyes dzinowanzo shandiswa se gain media. Gas lasers dzinoshandisa gas se gain medium, senge carbon dioxide gas mu carbon dioxide lasers, uye helium ne neon gas mu helium-neon lasers.Maseru eSemiconductorshandisa zvinhu zve semiconductor senzira yekuwana simba, zvakaita se gallium arsenide (GaAs).
Hunhu hukuru hwe laser gain medium hunosanganisira:
Maumbirwo esimba: Maatomu kana mamorekuru ari mu gain medium anofanirwa kuva nechimiro chakakodzera chesimba kuitira kuti huwandu hwevanhu hudzokere shure nekuda kwekusimudzirwa kwesimba rekunze. Izvi zvinowanzoreva kuti musiyano wesimba pakati pesimba repamusoro nerepasi unofanirwa kuenderana nesimba rephoton rewavelength yakati.

Zvimiro zvekuchinja: Maatomu kana mamorekuru ari mumamiriro ekufara anofanira kunge aine zvimiro zvekuchinja zvakagadzikana kuitira kuti abudise maphotoni akabatana panguva yemwaranzi inofashukira. Izvi zvinoda kuti gain medium ive nekushanda kwakawanda kwequantum uye kurasikirwa kushoma.
Kugadzikana kwekupisa uye simba remuchina: Mukushandiswa kwaro, gain medium inofanira kumira mwenje wepombi ine simba guru uye inobuda nelaser, saka inofanirwa kuva nekugadzikana kwakanaka kwekupisa uye simba remuchina.
Hunhu hweOptical: Hunhu hweOptical hweGain Medium hwakakosha pakushanda kweLaser. Inofanirwa kuve nemwenje wakawanda uye kurasikirwa kwakaderera kwekupararira kuti ive nechokwadi chekuti laser beam iri nani uye yakagadzikana. Kusarudzwa kweLaser Gain Medium kunoenderana nezvinodiwa zvekushandisa.laser, kureba kwemhepo kunoshanda, simba rekubuda kwezvinhu nezvimwe zvinhu. Nekugadzirisa zvinhu uye chimiro che gain medium, mashandiro uye kushanda zvakanaka kwelaser zvinogona kuvandudzwa zvakanyanya.
