Igipimo cy'ubugari bw'umurongo wa laser
Gupima ubugari bw'umurongo wa laser Hari uburyo bwinshi bwo gupima ubugari bw'umurongo wa laser: 1. Iyo ubugari bw'umurongo wa laser ari bunini (> 10 GHz, iyo uburyo bwinshi buzunguruka muri resonators nyinshi za laser), spectrometer zisanzwe zikoresha imigozi ya diffraction zishobora gukoreshwa mu gupima. Ariko, ubu buryo...Soma byinshi -
Laser yihuta cyane ku bumenyi bwa attosecond
Laser yihuta cyane ku bumenyi bwa attosecond. Muri iki gihe, imirasire ya attosecond iboneka ahanini binyuze mu gukora harmonic yo mu rwego rwo hejuru (HHG) iyobowe n'ibice bikomeye. Ishingiro ry'ikorwa ryabyo rishobora kumvikana nk'ibinyabutabire bihindurwamo iyoni, byihutishwa, kandi bigahuzwa n'umuriro ukomeye w'amashanyarazi wa laser...Soma byinshi -
Laser ya semiconductor ikoreshwa mu gukoranaho cyane ni iki?
Laser ya semiconductor ikoreshwa mu buryo bwagutse ni iki? Laser ikoreshwa hafi ya zose mu buryo bwo kumenya fibre optique (DOFS) kuko ishobora gushyira lasers zikomeye mu migozi. Ariko, hari ubwoko butandukanye bwa lasers, kandi hano ubwoko bw'ingenzi bushyirwa mu byiciro bikurikirana uko coh...Soma byinshi -
Incamake ngufi kuri Laser yo Guhindura Uburyo Buziguye
Incamake y'ibanze kuri Laser ya Direct Modulation Laser (DML Laser) igera ku ihinduka ry'ubushyuhe bw'urumuri binyuze mu kugenzura neza umuvuduko w'amashanyarazi wa laser. Laser ya DML ifite ibyiza byo kuba imiterere yoroshye, ihendutse, kandi yoroshye kuyihuza, kandi ikoreshwa cyane cyane mu ntera ngufi...Soma byinshi -
Laser iyobora igena aho urumuri rwa laser rwa attosecond rugarukira.
Laser iyobora igena aho urumuri rwa attosecond rugarukira. Kuri ubu, laser za attosecond pulse zikorwa ahanini binyuze mu gukora harmonic yo mu rwego rwo hejuru (HHG) itwarwa n'ibice bikomeye. Ishingiro ry'ikorwa ryazo rishobora kumvikana nk'i-electron zishyirwa mu buryo bwa iyoni, zikihutisha...Soma byinshi -
