Ukutsiba rhoqo 589 nm ifayibha frequency kabini laser
Inkcazo yemveliso
I-fiber ekhawulezayo yokutsiba i-Raman fiber single-pass frequency double double laser (RFA-SSHG JF) yaphuhliswa liqela le-Erbium ukuhlangabezana nemfuno ye-sodium lidar yokuguqulwa kwamaxesha ngama-589 nm laser.Ukwamkela i-ECDL yobubanzi obumxinwa kakhulu njengomthombo wembewu, Ukusebenzisa imodyuli yesantya esiphezulu sokutsiba rhoqo, ukwamkela yonke i-fiber Raman amplifier yokuphucula amandla e-laser kunye nekristale edlulayo yepolarization, iqela le-Erbium lifumana amandla aphezulu aphindaphinda i-laser ngokuxhuma rhoqo.Le mveliso inokufezekisa iziphumo ezimbini ze-laser ye-589 nm.Enye isetyenziselwa ukutshixa i-laser kumgca wokufunxa i-athomu yesodium ngokuphindaphindiweyo.Enye inkxaso ye-laser f+ 630MHz, F +0 MHz, F-630mhz yokutshintsha ngokukhawuleza.Amandla e-laser anokufikelela ngaphezu kwe-1.8 W, ehambelana ngokugqibeleleyo nemfuno yomthombo wembewu ye-sodium lidar.
