Co2 +: MgAl2O4 Isixhobo esitsha seSaturable Absorber Passive Q-switch

Icandelo lomnqamlezo oluphezulu lwe-3.5 x 10-19 cm2 livumela i-Q-switching ye-Er: i-glass laser ngaphandle kwe-intracavity egxininise zombini ngesibane se-flash kunye ne-diode-laser pumping. Ukufunxwa kwemeko echulumancisayo engathandekiyo kubangela umahluko omkhulu we-Q-switch, okt umlinganiselo wokuqala (umqondiso omncinci) ukuya kwi-absorption ehluthisiweyo ungaphezulu kwe-10. Ekugqibeleni, iipropathi ezigqwesileyo ze-optical, mechanical, kunye ne-thermal ye-crystal zinika ithuba lokuyila i-compact. kunye nemithombo ye-laser ethembekileyo ngolu tshintsho lwe-Q-switch.
Ubungakanani besixhobo buyancipha kwaye umthombo wamandla ombane ophezulu uyasuswa xa i-Q-switch okanye i-absorber e-saturable isetyenziselwa ukudala i-laser pulses yamandla aphezulu endaweni ye-electro-optic Q-switch. Ikristale eyomeleleyo, eyomeleleyo eyaziwa ngokuba yi-spinel polishes kakuhle. Ngaphandle kwe-ion yembuyekezo eyongezelelweyo, i-cobalt inokuthatha indawo ye-magnesium ngokulula kwi-spinel host. Kuzo zombini i-flash-lamp kunye ne-diode laser pumping, i-Er: i-glass laser's high absorption cross section (3.510-19 cm2) ivumela i-Q-switching ngaphandle kokugxila kwi-intracavity.
Umyinge wamandla ophumayo uya kuba yi-580 mW kunye nobubanzi be-pulse ephantsi njenge-42 ns kunye namandla ompompo afunnyiweyo we-11.7 W. Amandla ombane omnye we-Q-switched pulse abalwe ukuba abe malunga ne-14.5 J, kwaye amandla aphezulu angama-346 W. kwisantya sokuphindaphinda malunga ne-40 kHz. Kwakhona, amazwe amaninzi e-polarization ye-Co2+: LMA's passive Q switching action yavavanywa.
