Soo noqnoqoshada soo noqnoqda 589 nm fibre soo noqnoqda labanlaabmaya laser
Sharaxaada badeecada
Soo noqnoqoshada soo noqnoqda ee Raman fiber hal-pass soo noqnoqoshada laser labanlaabmaya (RFA-SSHG JF) waxaa sameeyay kooxda Erbium si ay u buuxiso baahida sodium lidar ee inta jeer ee loo beddelay laser 589 nm.Qaadashada ECDL oo dhererkeedu aadka u cidhiidhi yahay oo ah isha abuurka, Isticmaalka modulator xawaaraha sare ee soo noqnoqoshada soo noqnoqda, qaadashada dhammaan-fiber Raman amplifier si kor loogu qaado awoodda laysarka iyo hal mar oo soo noqnoqda polarization crystal, kooxda Erbium waxay helaysaa soo noqnoqda awoodda sare ee labanlaabmaysa leysarka oo leh soo noqnoqoshada soo noqnoqda.Alaabtani waxay gaari kartaa laba wax soo saar 589 nm laser ah.Mid ayaa loo isticmaalaa in lagu xidho laysarka xariiqda nuugista atomiga soodiyamka oo joogto ah.Laysarka kale wuxuu taageeraa f+ 630MHz, F +0 MHz, F-630mhz si degdeg ah u beddelashada.Awoodda laysarka waxay gaari kartaa in ka badan 1.8 W, kaas oo si fiican ugu dhigma baahida isha abuurka lidar sodium.
