Frequency hopping 589 nm fiber mita biyu Laser
Bayanin samfurin
Ƙungiya ta Erbium ta haɓaka mitar Raman fiber single-pass mitar Laser sau biyu (RFA-SSHG JF) don saduwa da buƙatar sodium lidar don mitar da aka canza na Laser 589 nm.Ɗauki ECDL matsananci-kunkuntar layi a matsayin tushen iri, Yin amfani da babban mai daidaita saurin saurin mita, ɗaukar duk-fiber Raman amplifier don haɓaka ikon Laser da kristal mai wucewa na lokaci-lokaci, ƙungiyar Erbium tana samun babban mitar wutar lantarki mai ninki biyu tare da hopping mita.Wannan samfurin zai iya cimma nau'ikan laser 589 nm guda biyu.Ana amfani da ɗaya don kulle Laser zuwa layin sha atom ɗin sodium a akai-akai.Sauran goyon bayan Laser f+ 630MHz, F +0 MHz, F-630mhz saurin sauyawa.Ikon Laser na iya kaiwa sama da 1.8 W, wanda yayi daidai da buƙatar tushen iri na lidar sodium.
