1. Kev Taw Qhia: Qhov Sib Npaug Tsis Zoo ntawm Laser Cavity

Lub laser helium-neon, lub hauv paus tseem ceeb ntawm photonics txij li thaum nws tsim tawm xyoo 1960, ua haujlwm ntawm lub hauv paus ntsiab lus ntawm kev sib npaug zoo. Nws cov xim liab 632.8 nm emission (lossis lwm cov kab zoo li 543.5 nm ntsuab) yog los ntawm cov txheej txheem hloov pauv zog nyuaj hauv cov pa roj qis qis. Ib qho sib xyaw ua ke muaj kwv yees li 90% helium thiab 10% neon ntawm tag nrho cov siab ntawm ob peb torr hauv lub raj plasma. Cov helium atoms raug txhawb nqa los ntawm kev tso tawm hluav taws xob, hloov lawv lub zog resonantly rau neon atoms, uas tom qab ntawd dhau los ua cov pej xeem inversion thiab txhawb nqa emission.

Cov txheej txheem no muaj kev phom sij heev rau kev ua qias tuaj. Hydrocarbons (roj pa), dej pa (H₂O), oxygen (O₂), nitrogen (N₂), thiab carbon dioxide (CO₂) ua haujlwm ua cov tshuaj tua hluav taws xob muaj zog. Lawv tuaj yeem:

• Collisionally De-excite cov neon atoms, txo cov pejxeem inversion.
• Nqus cov Photons ntawm qhov wavelength ntawm lub teeb, ua rau kev poob qis ntxiv.
• Cov Tshuaj Sib Xyaws ntawm cov electrodes thiab cov qhov ntawm lub qhov, ua rau muaj kev tsis ruaj khov ntawm qhov tso tawm, kev ua haujlwm hluav taws xob ntau ntxiv, thiab cov teebmeem "ntxuav" qhov twg roj raug siv tas mus li.
• Ua kom Cathode Sputtering nrawm dua, tso cov yeeb yaj kiab hlau rau ntawm daim iav thiab lub qhov, uas ua rau lub teeb tawg thiab thaum kawg tua lub laser.
