I-Passive Q-switches okanye i-absorber e-saturable ivelisa amandla aphezulu e-laser pulses ngaphandle kokusetyenziswa kwe-electro-optic Q-switches, ngaloo ndlela inciphisa ubungakanani bephakheji kunye nokuphelisa umbane ophezulu wombane.Co2+:MgAl2O4yinto entsha ngokwentelekiso yokwenziwa kwe-Q-switching kwi-laser ephuma kwi-1.2 ukuya kwi-1.6μm, ngokukodwa, kwi-eye-ekhuselekileyo ye-1.54μm Er: i-laser yeglasi, kodwa isebenza kwi-1.44μm kunye ne-1.34μm laser wavelengths.I-Spinel yikristale eqinile, ezinzileyo epholisha kakuhle.
