Co2+: MgAl2O4 Ihe Ọhụrụ Maka Ngbanwe Q-Switch Saturable Absorber Passive

Akụkụ obe dị elu nke 3.5 x 10-19 cm2 na-enye ikike Q-ịgbanwe nke Er: laser laser na-enweghị intracavity na-elekwasị anya ma na oriọna ọkụ na mgbapụta diode-laser. Negligible obi ụtọ-ala absorption nsonaazụ dị elu iche nke Q-switch, ntụgharị nke mbụ (obere mgbaàmà) ka jupụta absorption dị elu karịa 10. N'ikpeazụ, magburu onwe ngwa anya, n'ibu, na thermal Njirimara nke crystal na-enye ohere chepụta kọmpat. na isi iyi laser a pụrụ ịdabere na ya na Q-switch a na-agafe agafe.
A na-ebelata nha nke ngwaọrụ ahụ ma wepụ isi iyi ọkụ dị elu mgbe ejiri Q-switchs ma ọ bụ ihe ndị na-ekpo ọkụ saturable mee ihe iji mepụta ọkụ ọkụ laser dị elu kama iji electro-optic Q-switchs. kristal siri ike, siri ike mara dị ka spinel polishes nke ọma. Enweghị ion nkwụghachi ụgwọ ọzọ, cobalt nwere ike dochie magnesium n'ụzọ dị mfe na onye na-elekọta spinel. N'ihi na ma flash-lamp na diode laser pumping, na Er: iko laser elu absorption cross ngalaba (3.510-19 cm2) na-enye ohere Q-ịgbanwe na-enweghị intracavity ilekwasị anya.
Nkezi ike mmepụta ga-abụ 580 mW na obosara usu dị ka 42 ns na ike mgbapụta etinyere nke 11.7 W. A na-agbakọ ike nke otu usu Q-switched ka ọ bụrụ ihe dịka 14.5 J, na ike kacha elu bụ 346 W. na nkwughachi nke ihe dịka 40 kHz. Ọzọkwa, a nyochara ọtụtụ steeti polarization nke Co2+: LMA's passive Q switching act.
