Ubugari bwa pulse igenzura tekinoroji ya laser

Kugenzura ubugari bwa pulsekugenzuraikoranabuhanga

Igenzura rya pulse ya laser nimwe murwego rwingenzi muritekinoroji ya laser, bigira ingaruka ku buryo butaziguye imikorere n'ingaruka za laser. Uru rupapuro ruzatondekanya gahunda yo kugenzura ubugari bwa pulse, kugenzura impanuka ya tekinoroji hamwe na tekinoroji yo guhinduranya, kandi uharanira kuba umunyamwuga, wuzuye kandi wumvikana.

1. Igitekerezo cyubugari bwa pulse

Ubugari bwa Pulse bwa laser bivuga igihe cya laser pulse, nikintu cyingenzi kugirango dusobanure ibihe biranga ibisohoka. Kuri ultras-short pulse lasers (nka nanosekond, picosekond na femtosekond laseri), igihe kigufi kigari, imbaraga zo hejuru, hamwe ningaruka ziterwa nubushyuhe, bikwiranye no gutunganya neza cyangwa ubushakashatsi bwa siyansi.

2. Ibintu bigira ingaruka ku bugari bwa laser pulse Ubugari bwimpanuka ya laser bugira ingaruka kubintu bitandukanye, cyane cyane harimo ibi bikurikira:

a. Ibiranga inyungu ziciriritse. Ubwoko butandukanye bwunguka itangazamakuru rifite imbaraga zidasanzwe zurwego rwimiterere hamwe na fluorescence mubuzima bwose, bigira ingaruka muburyo bwibisekuru nubugari bwimisemburo ya laser pulse. Kurugero, ibyuma-bikomeye bya laseri, Nd: YAG kristu na Ti: kristu ya safiro nibisanzwe bikomeye-bya laser itangazamakuru. Lazeri ya gaze, nka lazeri ya karuboni (CO₂) na lazeri ya helium-neon (HeNe), ubusanzwe itanga impiswi ndende bitewe n'imiterere ya molekile hamwe na leta ishimishije; Amashanyarazi ya Semiconductor, mugucunga igihe cyo gutwara ibintu, irashobora kugera kubugari bwa pulse kuva kuri nanosekondi kugeza picosekond.

Igishushanyo mbonera cya laser gifite ingaruka zikomeye kubugari bwa pulse, harimo: uburebure bwurwobo, uburebure bwurwobo rwa laser bugena igihe gisabwa kugirango urumuri rugende rimwe na rimwe mu cyuho, umwobo muremure uzana ubugari burebure, mu gihe umwobo mugufi ufasha kubyara uduce duto duto cyane; Kuzirikana: Icyuma kigaragaza cyane kirashobora kongera ubwinshi bwa fotone mu cyuho, bityo bikagira ingaruka ku nyungu, ariko kugaragarira cyane birashobora kongera igihombo mu mwobo kandi bikagira ingaruka ku bugari bw’imitsi; Umwanya wo kunguka hagati hamwe nu mwanya wo kunguka hagati mu cyuho nabyo bizagira ingaruka kumikoranire hagati ya foton ninyungu zunguka, hanyuma bigire ingaruka mubugari bwa pulse.

c. Q-guhinduranya tekinoroji hamwe nuburyo bwo gufunga uburyo nuburyo bubiri bwingenzi bwo kumenya impanuka ya laser isohoka no kugenzura ubugari bwa pulse.

d. Inkomoko ya pompe nuburyo bwa pompe Imbaraga zihamye za pompe no guhitamo uburyo bwa pompe nabyo bigira ingaruka zikomeye mubugari bwa pulse.

3. Uburyo busanzwe bwo kugenzura ubugari

a. Hindura uburyo bwo gukora bwa laser: uburyo bwakazi bwa laser buzahindura muburyo bugari. Ubugari bwa pulse burashobora kugenzurwa muguhindura ibipimo bikurikira: inshuro nuburemere byamasoko ya pompe, ingufu zituruka kumasoko ya pompe, hamwe nurwego rwimibare yabaturage ihindagurika muburyo bwo kunguka; Kugaragaza ibyasohotse bisohora guhindura ibitekerezo neza muri resonator, bityo bikagira ingaruka kumikorere.

b. Kugenzura imiterere ya pulse: hindura mu buryo butaziguye ubugari bwimpiswi uhindura imiterere ya laser pulse.

c. Modulisiyo yubu: Muguhindura ibyasohotse mumashanyarazi kugirango agabanye ikwirakwizwa ryingufu za elegitoronike murwego rwa laser, hanyuma uhindure ubugari bwa pulse. Ubu buryo bufite umuvuduko wihuse kandi burakwiriye kubisabwa bisaba guhinduka byihuse.

d. Hindura modulasiyo: mugucunga imiterere ya laser kugirango uhindure ubugari bwa pulse.

e. Kugenzura ubushyuhe: ihinduka ryubushyuhe rizagira ingaruka kumurongo wa ingufu za electron, bityo bigira ingaruka kuburyo butaziguye ubugari bwa pulse.

f. Koresha tekinoroji ya modulisiyo: Tekinoroji ya modulasi nuburyo bwiza bwo kugenzura neza ubugari bwimitsi.

Guhinduratekinoroji ni tekinoroji ikoresha lazeri nk'itwara kandi ikayishyiraho amakuru. Ukurikije isano na lazeri irashobora kugabanywa muburyo bwimbere no guhinduranya hanze. Guhinduranya imbere bivuga uburyo bwo guhindura uburyo ibimenyetso byahinduwe byapakiwe murwego rwo guhindagurika kwa laser kugirango uhindure ibipimo bya lazeri bityo uhindure ibiranga lazeri. Guhinduranya hanze bivuga uburyo bwo guhinduranya ibimenyetso byongeweho nyuma yo gukora lazeri, kandi ibisohoka bya laser birahinduka bidahinduye ibipimo bya oscillation ya laser.

Tekinoroji ya modulasiyo irashobora kandi gushyirwa muburyo ukurikije uburyo bwo gutwara ibintu, harimo kugereranya, guhinduranya impiswi, guhinduranya imibare (pulse code modulasi); Ukurikije ibipimo byo guhindura, bigabanijwemo ubukana bwo guhindura no guhinduranya icyiciro.

Modulator: Ubugari bwa pulse bugenzurwa no guhindura ihinduka ryumucyo wa laser.

Icyiciro: Ubugari bwa pulse bwahinduwe muguhindura icyiciro cyumucyo.

Icyiciro gifunze amplifier: Binyuze mu cyiciro gifunze amplifier modulation, ubugari bwa laser pulse burashobora guhinduka neza.
