Umuvuduko wikurikiranya 589 nm fibre inshuro ebyiri laser
Ibisobanuro ku bicuruzwa
Umuvuduko wihuse wiringira Raman fibre imwe-pass inshuro ebyiri lazeri (RFA-SSHG JF) yakozwe nitsinda rya Erbium kugirango ihuze icyifuzo cya sodium lidar kuri frequency yahinduwe na 589 nm laser.Kwemera ultra-تارarike ya linewidth ECDL nkisoko yimbuto, Gukoresha modulator yihuta kugirango uhindure inshuro nyinshi, gukoresha fibre ya Raman amplifier yo kongera ingufu za laser hamwe na kode imwe ya polarisiyasi ya kirisiti, itsinda rya Erbium ryabonye ingufu nyinshi zikubye kabiri lazeri hamwe no kwizerwa.Ibicuruzwa birashobora kugera kubintu bibiri 589 nm bya laser.Imwe imwe ikoreshwa mugufunga lazeri kumurongo wa sodium atomic absorption kumurongo uhoraho.Ubundi laser ishyigikira f + 630MHz, F +0 MHz, F-630mhz yihuta.Imbaraga za laser zirashobora kugera kuri 1.8 W, zihuye neza nibisabwa nimbuto ya sodium lidar.
