I-Frequency hopping 589 nm fiber frequency double laser
Incazelo yomkhiqizo
I-Raman fiber single-pass frequency double hopping i-Raman fiber single-pass frequency laser (RFA-SSHG JF) yathuthukiswa iqembu le-Erbium ukuze ihlangabezane nesidingo se-sodium lidar ye-frequency eguqulwa ibe ngu-589 nm laser.Isebenzisa i-ECDL yobubanzi bomugqa obuncane kakhulu njengomthombo wembewu, Isebenzisa imodulator yesivinini esikhulu sokugxuma amaza, isebenzisa i-amplifier ye-fiber Raman yokuthuthukisa amandla e-laser kanye nekristalu ye-polarization edlulayo eyodwa edlulayo, iqembu le-Erbium lithola i-laser yamandla aphezulu ephindaphinda kabili nge-frequency jumping.Lo mkhiqizo ungafinyelela imiphumela emibili ye-laser engu-589 nm.Eyodwa isetshenziselwa ukukhiya i-laser emgqeni wokumuncwa kwe-athomu ye-sodium ngemvamisa engashintshi.Enye i-laser isekela i-f+ 630MHz, F +0 MHz, F-630mhz ukushintsha okusheshayo.Amandla e-laser angafinyelela ngaphezu kuka-1.8 W, ahambisana kahle nesidingo somthombo wembewu ye-sodium lidar.
