Co2+: MgAl2O4 Chida Chatsopano Kwa Saturable Absorber Passive Q-switch

Mayamwidwe apamwamba kwambiri a 3.5 x 10-19 cm2 amaloleza Q-kusintha kwa Er: laser laser popanda intracavity kuyang'ana zonse ndi nyali yamoto ndi kupopa kwa diode-laser. Mayamwidwe osagwirizana ndi dziko losangalatsa amabweretsa kusiyana kwakukulu kwa Q-switch, mwachitsanzo, chiŵerengero cha chiyambi (chizindikiro chaching'ono) kuti chilowetsedwe chodzaza ndi chapamwamba kuposa 10. Pomaliza, mawonekedwe abwino kwambiri a kristalo, opangidwa ndi makina, ndi otentha a kristalo amapereka mpata wopanga compact ndi magwero odalirika a laser okhala ndi Q-switch iyi.
Kukula kwa chipangizocho kumachepetsedwa ndipo gwero lamphamvu lamagetsi limachotsedwa pomwe ma Q-switches kapena ma saturable absorbers amagwiritsidwa ntchito kupanga ma pulses amphamvu a laser m'malo mwa ma electro-optic Q-switches. Mwala wolimba, wolimba womwe umadziwika kuti spinel polishes bwino. Popanda ma ion owonjezera olipira, cobalt imatha kusintha mosavuta magnesiamu mumtundu wa spinel. Pakupopa kwa nyale ndi diode laser, Er:glass laser's high absorption cross section (3.510-19 cm2) imalola Q-switching popanda kuyang'ana mkati mwa intracavity.
Avereji yamphamvu yotulutsa mphamvu ingakhale 580 mW yokhala ndi pulse m'lifupi mwake ngati 42 ns ndi mphamvu ya mpope ya 11.7 W. Mphamvu yamtundu umodzi wa Q-switched pulse inawerengedwa kuti ndi pafupifupi 14.5 J, ndipo mphamvu yapamwamba inali 346 W. pamlingo wobwereza pafupifupi 40 kHz. Komanso, mayiko angapo a polarization a Co2+: LMA's passive Q switching action adawunikidwa.
