Frequency hopping 589 nm faibha frequency kaviri laser
Tsanangudzo yechigadzirwa
Iyo inokurumidza frequency hopping Raman fiber single-pass frequency doubling laser (RFA-SSHG JF) yakagadziriswa neErbium boka kuti isangane nezvinodiwa zve sodium lidar ye frequency inoshandurwa ye589 nm laser.Kutora yekupedzisira-yakatetepa mutsara mutsara ECDL sesosi yembeu, Ichishandisa yakakwira yekumhanya modulator yekusvetuka-svetuka, kutora ese-fiber Raman amplifier yekunatsiridza laser simba uye imwe chete inopfuura periodic polarization crystal, Erbium boka rinowana yakakwira simba frequency yakapetwa kaviri laser ine frequency hopping.Ichi chigadzirwa chinogona kuwana maviri 589 nm laser kubuda.Imwe inoshandiswa kuvhara laser kune sodium atomic absorption mutsara pane inogara frequency.Imwe laser inotsigira f+ 630MHz, F +0 MHz, F-630mhz inokurumidza kuchinja.Simba relaser rinogona kusvika kupfuura 1.8 W, iro rinonyatsoenderana nekudiwa kwesodium lidar mhodzi sosi.
