Co: IiCrystals zeSpinel
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 +:MgAl2O4 yinto entsha ngokwentelekiso yokutshintsha kwe-Q kwi-laser ephuma kwi-1.2 ukuya kwi-1.6μm, ngokukodwa, kwi-1.54μm ekhuselekileyo ye-Er: i-glass laser, kodwa isebenza kwi-1.44μm kunye ne-1.34μm laser wavelengths.I-Spinel yikristale eqinile, ezinzileyo epholisha kakuhle.I-Cobalt ithatha indawo ye-magnesium ngokukhawuleza kwi-Spinel host ngaphandle kwesidingo se-ion yembuyekezo eyongezelelweyo.Icandelo lomnqamlezo oluphezulu (3.5 × 10-19 cm2) livumela i-Q-switching ye-Er: i-laser yeglasi ngaphandle kwe-intracavity egxininise zombini nge-flash-lamp kunye ne-diode laser pumping.Ukufunxa kwemeko echulumancisayo engafanelekanga kumlinganiselo ophezulu wokuchasana kwe-Q-switch, okt umlinganiselo wokuqala (umqondiso omncinci) ukuya kufunxa ohluthisiweyo ungaphezulu kwe-10.
