Co2 +: MgAl2O4 Cov Khoom Tshiab Rau Saturable Absorber Passive Q-hloov
Product Description
Kev nqus siab hla ntu ntawm 3.5 x 10-19 cm2 tso cai Q-hloov ntawm Er: iav laser yam tsis muaj intracavity tsom ob qho tib si nrog lub teeb nyem thiab diode-laser siv. Kev tsis txaus siab ntawm lub xeev nqus tau ua rau muaj qhov sib txawv ntawm Q-hloov, piv txwv li qhov piv ntawm thawj zaug (me me teeb liab) rau saturated absorption yog siab tshaj 10. Thaum kawg, zoo heev optical, mechanical, thiab thermal zog ntawm cov siv lead ua muab lub sij hawm los tsim compact. thiab txhim khu kev qha laser qhov chaw nrog no passive Q-hloov.
Qhov luaj li cas ntawm cov cuab yeej raug txo qis thiab lub zog hluav taws xob siab siab raug tshem tawm thaum passive Q-switches lossis saturable absorbers siv los tsim lub zog siab laser pulses es tsis txhob electro-optic Q-switches. Lub zog, khov kho siv lead ua hu ua spinel polishes nicely. Tsis muaj kev them nyiaj ntxiv ions, cobalt tuaj yeem hloov tau yooj yim magnesium nyob rau hauv tus tswv tsev spinel. Rau ob qho tib si flash-lamp thiab diode laser siv, Er: iav laser lub siab nqus hla ntu (3.510-19 cm2) tso cai rau Q-hloov yam tsis muaj kev tsom mus rau qhov chaw.
Qhov nruab nrab tso zis hluav taws xob yuav yog 580 mW nrog lub mem tes dav li qis li 42 ns thiab lub zog nqus twj tso kua mis ntawm 11.7 W. Lub zog ntawm ib qho Q-hloov mem tes tau suav tias yog kwv yees li 14.5 J, thiab lub zog siab tshaj plaws yog 346 W. ntawm ib tug repetition tus nqi ntawm txog 40 kHz. Tsis tas li ntawd, ntau lub xeev polarization ntawm Co2 +: LMA's passive Q switching action raug tshuaj xyuas.
