Okokuqala, ukuguquguquka kwangaphakathi nokuguqulwa kwangaphandle
Ngokusho kobudlelwano obuhlobene phakathi kwesimondi kanye ne-laser, theUkushintshwa kwe-laseringahlukaniswa ngokushintshana kwangaphakathi nokuguquguquka kwangaphandle.
01 Ukushintshwa Kwangaphakathi Kwangaphakathi
Isiginali yokushintshashintsha yenziwa ngenqubo ye-laser oscillation, okungukuthi, amapharamitha we-laser oscillation aguqulwa ngokuya ngomthetho wesiginali yokushintshanisa, ukuze ashintshe izici zomphumela we-laser futhi afeze ukushintshashintsha.

02 Ukushintshwa Kwangaphandle Kwangaphandle
Ukuguqulwa kwangaphandle ukwahlukanisa kwesizukulwane se-laser nokushintshashintsha. Kubhekiswa ekuthathweni kwesiginali elungiselelwe ngemuva kokwakhiwa kwe-laser, okungukuthi, i-modulator ibekwa endleleni ye-laser resonator.
I-Modal Signal Voltage ingezwe ku-modulator ukwenza izici ezithile zomzimba zeSigaba Sokuguqula Isigaba, kwathi lapho i-laser idlula kuyo, amanye amapharamitha egagasi aguqukayo, ngaleyo ndlela ephethe imininingwane okufanele idluliselwe kuyo. Ukuguquguquka kwangaphandle akuwona ukuguqula amapharamitha we-laser, kepha ukushintsha amapharamitha we-laser yokuphuma, njengokuqina, imvamisa, njalonjalo.
Okwesibili,I-Laser Modulatorukuhlela ngohlobo oluthile
Ngokwendlela yokusebenza yesimondi, ingahlukaniswa kuyoUkushintshwa kwe-electro-optic, Ukuguqulwa kwe-Acoustooptic, ukuguquguquka kwe-magneto-optic nokuguquguquka okuqondile.
01 Ukushintshwa okuqondile
Ukushayela kwamanjeI-Semiconductor Lasernoma i-diode ekhanyayo ekhanyayo ilungiswe ngokuqondile ngesiginali kagesi, ukuze ukukhanya okuphuma kuguqulwe ngokushintshwa kwesiginali kagesi.
(1) Ukushintshwa kwe-TTL ekushintshisaneni okuqondile
Isiginali yedijithali ye-TTL yengezwa kumandla we-laser wamandla, ukuze i-laser drive yamanje ingalawulwa ngesiginali yangaphandle, bese kuthi imvamisa ye-laser akepuct ingalawulwa.
(2) Ukushintshwa kwe-analog kuguquko oluqondile
Ngaphezu kwesiginali ye-analog yamandla we-laser (amplitude ngaphansi kwe-5V Translary Guqula i-wave ye-5v
Ukuguqulwa kwe-electro-optic
Ukushintshwa kwe-Electro-Optic Effect kubizwa ngokuthi ukuguquguquka kwe-electro-optic. Isisekelo somzimba se-Electro-Optic Effection yi-Electro-Optic Effect, okungukuthi, ngaphansi kwesenzo senkambu kagesi esetshenzisiwe, inkomba yamakristalu athile izoshintsha, futhi lapho igagasi elikhanyayo lidlula kulolu hlelo, izici zalo zokuhambisa zizothinteka futhi ziguqulwe.
Ukushintshwa kwe-Acousto-Optic
Isisekelo somzimba sokuguqulwa kwe-acousto-optic i-acousousto-optic umphumela, obhekise emcimbini onamagagasi akhanyayo asetshenziswa noma asakazeke yinkambu yegagasi engaphezu kwemvelo lapho kusakazwa okuphakathi nendawo. Lapho inkomba evumayo yezinguquko eziphakathi nendawo ukwakha i-Index ye-Index ye-Index, i-DifTraction izovela lapho amagagasi akhanyayo asakazeka endaweni ephakathi nendawo, futhi ubukhulu kanye nokuqondisa kokukhanya okuhlukile kuzoshintsha ngoshintsho lwensimu ye-supergenated wave.
Ukushintshwa kwe-Acousto-Optic kuyinqubo ebonakalayo esebenzisa umphumela we-acousto-optic umphumela wokulayisha imininingwane kwi-Optical Frequency Carrier. Isiginali elungisiwe senziwa ku-Electro-Acoustic TransDucer ngesibonakaliso sikagesi (Amplitude Modal), kanye nesiginali kagesi ehambisanayo iguqulwa ibe yinkambu ye-ultrasonic. Lapho igagasi elikhanyayo lidlula nge-acousousto-optic medium, i-optical carrier ilungisiwe futhi iba yigagasi elilinganiselwe elilinganiselwe elithi "lithwala" imininingwane.
04 Ukushintshwa kwe-Magneto-Optical
I-Magneto-Optic Movie - Ukusetshenziswa kwe-FaraDay's Electromagnetic Aptical Rocketation Detation Effect. Lapho amagagasi akhanyayo asakazeka ngokusebenzisa i-Magneto-Optical Medium Parallel ekuqondisweni kwamandla kazibuthe, into yokujikeleza kwendiza yokugwaza yokukhanya okukhanyayo okuqondile kubizwa ngokuthi ukukhanya kwama-polarized.
Kusetshenziswa amandla kazibuthe ahlala njalo kusetshenziswa ku-Medium ukufeza ukugcwala kwamandla. Ukuqondiswa kwamandla kazibuthe wesekethe kusesiholweni se-axial se-medium, kanye ne-faraday ukujikeleza kuncike kwi-axial yama-magnetic yama-magnetic yama-axial yamanje. Ngakho-ke, ngokulawula okwamanje kwekhoyili ephezulu kakhulu futhi eshintsha amandla esikhunzi ama-axial, i-angle ejikelezayo yendiza ye-optical vibration ingalawulwa, ukuze ukukhanya okukhanyayo nge-polarizer kushintsha ngokushintshwa kwe-θ angle, ukuze kufinyelelwe ukuguquguquka.
