I-Co2+: I-MgAl2O4 Into Entsha Ye-Saturable Absorber Passive Q-switch
Incazelo Yomkhiqizo
Isigaba esiphambanayo sokumuncwa okuphezulu esingu-3.5 x 10-19 cm2 sivumela ukushintshwa kwe-Q kwe-Er:ingilazi yengilazi ngaphandle kwe-intracavity egxile kukho kokubili ngesibani esikhanyayo nokumpompa i-diode-laser. Ukumuncwa kwesimo senjabulo enganakwa kuphumela ekuhlukeni okuphezulu kwe-Q-switch, okusho ukuthi isilinganiso sokuqala (isiginali encane) nokumunca okugcwele singaphezu kuka-10. Ekugcineni, izici ezinhle kakhulu zokubuka, zemishini, nezokushisa zekristalu zinikeza ithuba lokuklama okuhlangene. kanye nemithombo ye-laser enokwethenjelwa enale nguquko ye-Q engenzi lutho.
Usayizi wedivayisi uyancishiswa futhi umthombo wamandla kagesi aphezulu uyasuswa lapho ama-Q-switch noma ama-absorber agcwalayo asetshenziswa ukuze kwakheke ama-laser amandla aphezulu esikhundleni sokushintsha kwe-electro-optic Q-switches. Ikristalu eqinile, eqinile eyaziwa ngokuthi i-spinel polishes kahle. Ngaphandle kwama-ion esinxephezelo engeziwe, i-cobalt ingase ithathe indawo ye-magnesium kalula kumsingathi we-spinel. Kukho kokubili ukumpompa kwe-flash-lamp kanye ne-diode laser, isigaba se-Er:glass laser's high absorption cross (3.510-19 cm2) sivumela ukushintsha kwe-Q ngaphandle kokugxilisa i-intracavity.
Amandla okukhiphayo amaphakathi angaba ngu-580 mW nobubanzi bepulse obuphansi obungama-42 ns kanye namandla epompo amuncwa angu-11.7 W. Amandla e-pulse eyodwa eshintshwayo ye-Q abalwe ukuthi acishe abe ngu-14.5 J, futhi amandla aphezulu ayengu-346 W. ngesilinganiso sokuphindaphinda esingaba ngu-40 kHz. Futhi, izimo ezimbalwa ze-polarization ze-Co2+:Isenzo sokushintshwa kwe-LMA sika-Q esiguquliwe siye sahlolwa.
