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.Co2+:MgAl2O4iwumsebenzi 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.
