Laysarka Diode godka dibadda ee go'an
Sharaxaada badeecada
Marka la barbar dhigo laysarka diode ee soo jireenka ah ee dibadda, FECL (laser leyser diode cavity dibadda ah oo go'an) kuma laha wax la dhaqaajin karo oo ku jira qaab dhismeedka.Sidaas awgeed waxay awood u leedahay inay ku shaqeyso kala duwanaanshaha heerkulka deegaanka ee culus iyo gariirka, oo weli xor ka ah hab-hop.
Qaadashada tignoolajiyada xidhidhiyaha laysarka diode isgaadhsiinta, kooxda Erbium waxay FECL ku soo saartay xidhmo-balbalisooyin yar.Dhanka kale iyada oo leh sawaxan yar iyo darawal sare-bandwidth-bandhige, Precilasers' FECL waxay muujinaysaa xariiqda aadka u cidhiidhi ah (< 10 kHz), qaylada xoogga hoose ee aadka u hooseeya (<-150 dBc / Hz @ 100 kHz), iyo xajmiga xajmiga weyn (> 5MHz). ).
FECL waxaa si weyn loogu isticmaalaa meelaha sida saacada atomiga la qaadi karo, iyo mitirka cuf-jiidadka, muraayad indhaha, radar, isgaarsiinta indhaha ee isku xiran, dareenka indhaha ee saxda ah, cabbirka quantum
