Co2+: MgAl2O4 Chishandiso Chitsva cheSaturable Absorber Passive Q-switch
Product Description
High absorption cross chikamu che3.5 x 10-19 cm2 inobvumira Q-kuchinja kweEr: girazi laser isina intracavity inotarisa zvese nemwenje wemwenje uye diode-laser kupomba. Negligible excited-state absorption inoguma mukusiyana kukuru kweQ-switch, kureva chiyero chekutanga (chiratidzo chidiki) kusvika pakunyura kwakazara kwakakwira kupfuura 10. Pakupedzisira, yakanakisa optical, mechanical, uye thermal properties yecrystal inopa mukana wekugadzira compact. uye yakavimbika laser masosi neiyi passive Q-switch.
Saizi yechishandiso inodzikiswa uye yakakwira voltage sosi yemagetsi inobviswa kana passive Q-swichi kana saturable absorbers inoshandiswa kugadzira yakakwira simba laser pulses pachinzvimbo che electro-optic Q-swichi. Iyo yakasimba, yakasimba crystal inozivikanwa sespinel polishes zvakanaka. Pasina imwe mari yekubhadharisa ions, cobalt inogona kutsiva nyore magnesium mune spinel host. Kune ese ari maviri mwenje-mwenje uye diode laser kupomba, iyo Er: girazi laser's yakakwirira absorption cross chikamu (3.510-19 cm2) inobvumira Q-kuchinja pasina intracavity yakatarisa.
Avhareji yekubuda kwesimba yaizova 580 mW ine pulse width yakaderera se42 ns uye simba repombi rakatorwa re 11.7 W. Simba reimwe Q-switched pulse yakaverengwa kuva inenge 14.5 J, uye simba repamusoro raiva 346 W. pachiyero chekudzokorora chinenge 40 kHz. Zvakare, akati wandei polarization nyika dzeCo2 +: LMA's passive Q switching chiito chakaongororwa.
