Txoj Cai Kev Ua Haujlwm:
Pumping: Cov txheej txheem pib nrog lub twj tso kua mis ntawm qhov nce nruab nrab. High-power diode lasers yog siv los xa lub zog rau ytterbium-doped disk, txhawb cov electrons mus rau qib siab zog.
Population Inversion: Raws li cov electrons nyob rau hauv nruab nrab nce nqus zog los ntawm lub twj tso kua mis qhov chaw, lawv mus txog lub xeev zoo siab, tsim ib tug pej xeem inversion. Qhov no yog ib qho tsim nyog rau lasing tshwm sim.
Spontaneous Emission: Qee qhov zoo siab electrons spontaneously rov qab mus rau qis zog xeev, emitting photons nyob rau hauv tus txheej txheem. Txawm li cas los xij, cov photons no tsis sib koom ua ke thiab tsis pab txhawb rau laser amplification.
Stimulated Emission: Thaum lub photon ntsib ib qho kev zoo siab electron nyob rau hauv qhov nruab nrab qhov nce, nws tuaj yeem txhawb cov electron kom rov qab mus rau lub zog qis dua, emitting ib coherent photon nrog tib lub zog, theem, thiab kev taw qhia raws li qhov teeb meem photon. Cov txheej txheem no yog qhov tseem ceeb ntawm kev txhawb nqa emission, uas ua rau muaj kev nthuav dav ntawm cov teeb pom kev zoo.
Resonator Cavity: Lub resonator kab noj hniav, tsim los ntawm ob daim iav, ib qho uas muaj kev cuam tshuam zoo heev thiab lwm qhov pob tshab, tso cai rau lub teeb sib xyaw ua ke los tsim kom muaj zog thaum nws rov qab los ntawm daim iav. Cov txheej txheem amplification no ua rau muaj qhov zoo-txhais, zoo laser beam tawm los ntawm daim iav pob tshab.
Output Coupling: Ib feem ntawm daim iav pob tshab, lub npe hu ua qhov tso zis txuas, tso cai rau ib feem ntawm lub teeb pom kev zoo tawm ntawm kab noj hniav raws li qhov tso zis tawm. Lub teeb uas tseem tshuav txuas ntxiv mus rau hauv kab noj hniav, txuas ntxiv rau lub laser.
Qhov zoo ntawm Disk Lasers:
Kev Tswj Thermal: Cov txheej txheem nyias-disk ua kom txias txias, txo qis thermal distortions thiab tso cai rau kev rho tawm ntawm cov kab hluav taws xob laser siab.
