Iyini i-laser ye-semiconductor yokuxhumana okubanzi
Kuyini i-laser ye-semiconductor yokuxhumana ebanzi. Ama-Laser asetshenziswa cishe kuzo zonke izinhlelo zokuzwa ze-fiber optic ezisabalalisiwe (i-DOFS) ngoba angafaka ngempumelelo ama-laser anamandla aphezulu kuma-fiber. Kodwa-ke, kunezinhlobo ezahlukene zama-laser, futhi lapha izinhlobo eziyinhloko zethulwa ngokulandelana kokwanda...Funda kabanzi -
Isingeniso esifushane se-Direct Modulation Laser
Isingeniso esifushane se-Direct Modulation Laser I-Direct Modulation Laser (i-DML Laser) ifinyelela ukuguqulwa kwamandla okukhanya ngokulawula ngqo amandla okushayela e-laser. I-DML laser inezinzuzo zesakhiwo esilula, izindleko eziphansi, kanye nokuhlanganiswa okulula, futhi isetshenziswa kakhulu kuma-com...Funda kabanzi -
I-laser eshayelayo inquma umkhawulo ophezulu womthombo wokukhanya we-laser we-attosecond
I-laser eshayelayo inquma umkhawulo ophezulu womthombo wokukhanya we-laser ye-attosecond. Njengamanje, ama-laser e-attosecond pulse akhiqizwa kakhulu ngokusebenzisa i-high-order harmonic generation (HHG) eqhutshwa amasimu aqinile. Ingqikithi yokukhiqizwa kwawo ingaqondwa njengama-electron aguqulwa abe yi-ion, asheshise...Funda kabanzi -
Umklamo wendlela yokubona we-laser ekhiyiwe ngemodi engu-66-femtosecond
Umklamo wendlela yokubona we-laser enemodi ekhiyiwe engu-66-femtosecond Le laser enemodi ekhiyiwe engu-66-femtosecond iyi-laser yefayibha ene-ytterbium egcina i-polarization yonke ene-shifter yesigaba esingashintshi. Ifinyelela ukukhiyiwa kwemodi yemvamisa eyisisekelo engu-147 MHz. Ngokulungisa ibanga phakathi...Funda kabanzi -
