I-Co: Spinel Crystals
Ama-Passive Q-switches noma ama-absorber agcwala amandla akhiqiza amandla amakhulu ama-laser pulses ngaphandle kokusebenzisa ama-electro-optic Q-switches, ngaleyo ndlela ehlisa usayizi wephakheji futhi aqede ukunikezwa kwamandla kagesi aphezulu.I-Co2+:MgAl2O4 iwumsebenzi omusha uma kuqhathaniswa wokushintsha kancane kwe-Q kuma-lasers aphuma ku-1.2 kuye ku-1.6μm, ikakhulukazi, ku-1.54μm Er:ingilazi yengilazi ephephile, kodwa futhi isebenza ku-1.44μm kanye no-1.34μm wamaza we-laser.I-Spinel iyikristalu eqinile, ezinzile epholisha kahle.I-Cobalt ithatha indawo ye-magnesium kalula kumsingathi we-Spine ngaphandle kwesidingo sama-ion esinxephezelo engeziwe.Isigaba esiphambanayo sokumuncwa okuphezulu (3.5×10-19 cm2) sivumela ukushintshwa kwe-Q kwe-Er:ingilazi yengilazi ngaphandle kwe-intracavity egxile kokubili ngesibani esikhanyayo kanye nokumpompa ngelaser ye-diode.Ukumuncwa kwesimo senjabulo enganakwa kuphumela kusilinganiso sokungafani okuphezulu kwe-Q-switch, okusho ukuthi isilinganiso sokuqala (isiginali encane) nokumunca okugcwele singaphezulu kuka-10.
