Qhia Txog Cov Lus Qhia Txog Laser Modulator Tshuab

Luv luv Cov lus qhia ntawm lasertus modulatortej txuj ci tshiab
Laser yog lub zog hluav taws xob ntau hauv hluav taws xob, vim yog nws txoj kev sib tw zoo, zoo li siv hluav taws xob thiab TV), raws li cov cab kuj mus xa cov ntaub ntawv. Cov txheej txheem ntawm cov ntaub ntawv thauj mus rau laser hu ua kev hloov pauv, thiab cov cuab yeej uas ua cov txheej txheem no yog hu ua tus modulator. Hauv cov txheej txheem no, laser ua raws li cov cab kuj, thaum lub teeb liab qis uas tau xa cov ntaub ntawv hu ua cov teeb liab modulated.
Laser hloov feem ntau muab faib ua kev ua haujlwm sab hauv thiab kev sib kho sab nraud ob txoj kev. Kev hloov kho sab hauv: yog hais txog kev hloov kho hauv cov txheej txheem laser oscillation, yog li cuam tshuam rau cov khoom tawm ntawm cov yam ntxwv ntawm lub laser. Muaj ob txoj hauv kev ntawm kev hloov kho sab hauv: 1. Ncaj ncees lub zog tso hluav taws xob ntawm lub laser kom kho qhov siv ntawm cov zis laser. Los ntawm kev siv lub teeb liab los tswj cov roj av siv hluav taws xob laser hluav taws xob, lub laser log zog tuaj yeem tswj tau los ntawm lub teeb liab. 2. Cov ntsiab lus tswj tau muab tso rau hauv tus resonator, thiab cov yam ntxwv ntawm lub teeb liab uas tau hloov pauv kom ua tiav cov kev hloov kho ntawm laser. The advantage of internal modulation is that the modulation efficiency is high, but the disadvantage is that because the modulator is located in the cavity, it will increase the loss in the cavity, reduce the output power, and the bandwidth of the modulator will also be limited by the passband of the resonator. Kev Tawm Tsam Sab Nraud: txhais tau tias tom qab tsim ntawm lub laser, tus modulator tau hloov pauv nrog cov teeb tsa kho qhov muag, thiab thaum lub teeb ci ntsa iab los ntawm cov qauv hloov kho ntawm lub teeb dej hiav txwv. The advantages of external modulation are that the output power of the laser is not affected and the bandwidth of the controller is not limited by the passband of the resonator. Qhov tsis zoo yog qhov muaj kev ua haujlwm tsawg.
Laser kev hloov kho tuaj yeem muab faib ua qhov hloov pauv, zaus kev hloov kho, theem hloov kho thiab cov khoom siv hloov kho raws li cov khoom siv. 1, qhov dav tawm hloov kho: qhov kev tawm tsam yog cov oscillation uas lub ncu ntawm cov cab kuj hloov nrog txoj cai ntawm cov teeb liab modulated. 2, Zaus Tes Tesulation: los hloov cov teeb liab los hloov cov zaus ntawm laser oscillation. 3, theem hloov kho: los hloov cov teeb liab los hloov cov theem ntawm laser oscillation laser.

Electro-optical siv modulator
Lub hauv paus ntsiab lus ntawm electro-optic kev siv tshuab yog kom paub qhov kev cuam tshuam ntawm kev cuam tshuam lub teeb ci ntsa iab los ntawm kev siv lub electro-optic cuam tshuam ntawm cov siv leado. Lub tshuab hluav taws xob tawm ntawm lub crystal yog hais txog qhov tshwm sim ntawm lub teeb ntawm lub crystal kev hloov pauv hauv qab, yog li ntawd lub xeev hloov pauv.

Electro-Optic Theem Modulator
Electro-optical theem modelation compulation cov ntsiab cai: theem kaum ntawm Laser Oscillation hloov tau hloov los ntawm txoj cai ntawm kev teeb tsa.

Ntxiv rau cov saum toj Electro-optic siv tshuab hluav taws xob thiab muaj ntau yam kev kho mob
