Inzira nyamukuru ya tekinike yo guhuzaInzira-ndendehamwe na semiconductor yo hanze

Impinduka zifunguye-umurongo wa lazeri nurufatiro rwibikorwa byinshi mubice nka fiziki ya atome, spekitroscopi, amakuru ya kwant, itumanaho rifatika, kumva kure, no gupima neza. Muri iyi mirima, yoroshye, ihendutse, irambuye umurongo mugari hamwe na lazeri yagutse izakomeza gutwara porogaramu nshya zikoranabuhanga.

Mu myaka 50 ishize, amateka yaisoko yumucyoTLS Laser ahanini yerekanye iterambere ryikoranabuhanga rya laser. Irangi ryambere ryirangi ryasimbujwe na lazeri yo hanze ya cavity diode (ECDLs), mugihe sisitemu yingufu nyinshi yiganjemo lazeri ikomeye ya reta (nka titanium-safiro) cyangwa lazeri ihinduranya Nd: YAG ikoresha oscillator optique (OPO). Lazeri ya diode idafite umwobo wimbere wuzuye yujuje ibiciro bidahenze kandi bidafite isoko rito birangirana nubucuruzi bwa DFB Laser na DBR ya diode, hamwe nubugari bwumurongo bugufi nka 500kHz. Vuba aha, fibre fibre hamwe na variable-frequency fibre lazeri yatangiye gusimbuza sisitemu nyinshi zikomeye-zuburyo butandukanye, zitanga imbaraga zisumba izindi kandi zihindagurika, cyangwa ubugari bwumurongo. Muri iki gihe, kugaragara kw'ibimamara bya franse bifasha lazeri-itajegajega ya lazeri kugerwaho ku burebure ubwo aribwo bwose mugihe hagumyeho umutekano uhamye kandi neza. Ariko, nubwo bimeze gurtyo, umwobo wo hanzesemiconductor laseriracyakomeza imiterere yayo nkisoko yumucyo ikoreshwa muri laboratoire nyinshi kubera ubworoherane, imikorere-myinshi, imikorere yubahwa nigiciro gito cyane.

Kugeza ubu, ibyuma bifata umurongo-bigabanya umurongo hamwe na semiconductor yo hanze byashyizwe mu bikorwa:

Gukonjesha no gufata

Bose-Einstein

Quantum Optics: Umucyo ucanye

Electromagnetic ibonerana kandi itinda

Ibihe hamwe ninshuro

Laser spectroscopy

Impinduka zifunganye-umurongo wa lazeri mubusanzwe igizwe numugenzuzi, diode ya laser hamwe na module yo guhitamo inshuro. Kurugero, ibishishwa bikoreshwa muguhitamo lazeri no guhuza, cyangwa kuyungurura bishingiye kumiterere yijisho ryinjangwe, nibindi. Kugirango ugere kumurongo mwinshi wa laser, ubwoko butandukanye bwa laser frequency-gufunga module irashobora kongerwamo. Kurugero, ukoresheje tekinoroji ya PDH yumwanya wo gufunga uburebure bwa laser kumurongo wa optique super-stabilite, umurongo wa lazeri urashobora kugabanuka kugera kurwego rwa 1 Hz, kandi guhagarara kwumurongo bishobora kugera kuri <3 × 10-15 @ 1 s.
