Kuthamanga pafupipafupi kwa 589 nm fiber frequency kuwirikiza laser
Kufotokozera kwazinthu
Makina othamanga pafupipafupi a Raman fiber single-pass frequency double double laser (RFA-SSHG JF) adapangidwa ndi gulu la Erbium kuti akwaniritse kufunikira kwa sodium lidar pafupipafupi kutembenuzidwa kwa 589 nm laser.Kutengera utali wopapatiza kwambiri wa ECDL ngati gwero la mbewu, Kugwiritsa ntchito modulitsa wothamanga kwambiri podumphira pafupipafupi, kugwiritsa ntchito amplifier ya Fiber Raman kuti muwonjezere mphamvu ya laser ndi kristalo wapolarization wodutsa nthawi imodzi, gulu la Erbium limapeza laser yamphamvu pafupipafupi yowirikiza kawiri ndi kudumpha pafupipafupi.Izi zitha kukwaniritsa zotulutsa ziwiri za 589 nm laser.Imodzi imagwiritsidwa ntchito kutseka laser ku mzere wa sodium atomic mayamwidwe pafupipafupi.Laser ina imathandizira f+ 630MHz, F +0 MHz, F-630mhz kusintha mwachangu.Mphamvu ya laser imatha kupitilira 1.8 W, yomwe imagwirizana bwino ndi gwero lambewu ya sodium lidar.
