Kafaffen Cavity Diode Laser na waje
Bayanin samfurin
Idan aka kwatanta da laser diode cavity na waje na gargajiya, FECL (kafaffen cavity diode laser) ba shi da abubuwa masu motsi a cikin tsarin.Don haka yana iya yin aiki a ƙarƙashin matsanancin yanayin zafin yanayi da rawar jiki, har yanzu babu yanayin hop.
Karɓar fasahar marufi na diode Laser sadarwar gani, ƙungiyar Erbium ta haɓaka FECL a cikin ƙaramin fakitin malam buɗe ido.A halin yanzu tare da ƙaramar amo da babban direba-bandwidth mai daidaitawa, Precilasers' FECL yana nuna kunkuntar layin layi (< 10 kHz), ƙaramin ƙarar ƙarar ƙarar (<-150 dBc / Hz @ 100 kHz) , da babban bandwidth modulation (> 5MHz). ).
Ana amfani da FECL sosai a cikin yankuna kamar agogon atomic mai ɗaukar nauyi, da mitar nauyi, lattice na gani, radar, sadarwa mai daidaituwa, ingantaccen tsinkaye na gani, ƙididdigar ƙima.
