Ugboro hopping 589 nm eriri ugboro ugboro abụọ laser
Nkọwa ngwaahịa
Otu Erbium mepụtara ngwa ngwa na-agba ọsọ Raman fiber single-pass ugboro ugboro abụọ laser (RFA-SSHG JF) iji gboo ọchịchọ nke sodium lidar maka ugboro ntụgharị nke laser 589 nm.Inweta ECDL ultra-warara linewidth dị ka isi mkpụrụ, N'iji modulator dị elu maka hopping ugboro ugboro, na-anakwere ihe niile-fiber Raman amplifier maka ịkwalite ike laser na otu kristal polarization na-agafe agafe, otu Erbium na-enweta ike dị elu ugboro abụọ na-agbagharị ugboro ugboro.Ngwaahịa a nwere ike nweta nsonaazụ laser 589 nm abụọ.A na-eji otu agbachi laser na eriri absorption sodium atomic n'otu oge.Laser ọzọ na-akwado f+ 630MHz, F +0 MHz, F-630mhz na-agbanwe ngwa ngwa.Ike laser nwere ike iru karịa 1.8 W, nke dabara nke ọma n'ọchịchọ nke isi mmalite mkpụrụ sodium lidar.
