Frequency hopping 589 nm fiber frequency double laser
Tlhaloso ea sehlahisoa
Raman fiber single-pass frequency doubling laser (RFA-SSHG JF) e potlakileng ea maqhubu a hopping e entsoe ke sehlopha sa Erbium ho fihlela tlhoko ea sodium lidar bakeng sa frequency e fetoletsoeng ea 589 nm laser.Ho amohela ECDL ea bophara bo moqotetsane joalo ka mohloli oa peo, Ho sebelisa modulator ea lebelo le phahameng bakeng sa ho tlola khafetsa, ho amohela amplifier ea fiber ea Raman bakeng sa ho matlafatsa matla a laser le kristale e fetang e le 'ngoe ea polarization, sehlopha sa Erbium se fumana laser ea matla a phahameng a imenang habeli ka ho tlola khafetsa.Sehlahisoa sena se ka fihlella liphetho tse peli tsa laser 589 nm.E 'ngoe e sebelisetsoa ho notlela laser moleng oa ho monya athomo ea sodium ka makhetlo a mangata.Laser e 'ngoe e tšehetsa f+ 630MHz, F +0 MHz, F-630mhz e fetohang ka potlako.Matla a laser a ka fihla ho feta 1.8 W, e lumellanang hantle le tlhoko ea mohloli oa peo ea sodium lidar.
