Ingufu za Laser

Ingufu za Pulse za laser bivuga ingufu zatanzwe na laser pulse kuri buri gihe. Mubisanzwe, lasers irashobora gusohora imiraba ikomeje (cw) cyangwa ipakijwe, hamwe na nyuma ari ngombwa cyane mubisabwa byinshi nkibitunganya ibintu, kwiyubaha, ibikoresho byubuvuzi, nubushakashatsi bwubuvuzi. Gusobanukirwa ibiranga ingufu za laser pulse ningirakamaro kugirango utegure imikorere yayo no kuzamura imikorere myiza.

1. ibisobanuro no gupima ingufu za pulse

Ingufu za Laser Pulse ni ingufu zashyizwe ahagaragara na buri Laser Pulse, ubusanzwe yapimwe muri joules (j). Bitandukanye n'umuhengeri uhoraho (cw) lasers, lasers ya lasers itakaza ingufu mugihe gito, kandi ubunini bwingufu mubisanzwe bifitanye isano nibihe bya pulse (ubugari bwa pulse) nimbaraga za pulle.

Ingufu za Pulse zirashobora kubarwa ukoresheje formula ikurikira: e = pPak × τ. Aho e ari ingufu za pulse (sholes), PPAAK nimbaraga zimpanuka za pulse (watts), na τ nigihome cyinshi (amasegonda). Ibi bivuze ko ingufu za Pulse zifitanye isano itaziguye nimbaraga za peak nubugari bwa Pulse.

2. Ibintu bireba ingufu za pulse

Ibintu byinshi bigira ingaruka ku mbaraga za laser, harimo:

①Igishushanyo cya Laser n'ubwoko:
Ubwoko butandukanye bwa lazeri bugira ingaruka ku bunini bw'ingufu za pulse. Kurugero, abahiga bakomeye mubisanzwe batanze ingufu zisumba izindi, zibereye gusaba gusohoza amashanyarazi menshi. Abahinze fibre, kurundi ruhande, barashobora kubyara paki nimbaraga zisumba izindi zo guhindura uburebure.

②Igihe cya Pulse (Ubugari bwa Pulse):
Ubugari bugufi cyane, imbaraga zo hejuru cyane mugihe runaka, zituma ingufu zisumba izindi. Ubugari bwa Pulse muri Pulsers mubisanzwe buhinduka hagati ya Nanoseconds na PioseConds, hamwe na Plispindo ngufi ikoreshwa cyane mugukoresha neza cyane kubera imbaraga zabo zo hejuru.

③Imbaraga za Laser hamwe no guhindura ingufu:
Imikorere ya laser igena ibisohoka byingufu. Sisitemu zimwe za laser zirashobora kuzamura imikorere muguhindura igishushanyo mbonera cyimbogamizi cyangwa umwobo wa laser, bityo ukure imbaraga za pulse.

④Laser Amplifiers:
Muri sisitemu nyinshi za laser ya laser, amplifiers ikoreshwa mugutera imbaraga zisohoka. Binyuze muri byinshi-byongerewe, ingufu zijimye zirashobora kuzamuka cyane.

⑤Laser Drive Yubu:
Imodoka igezweho ya laser diode cyangwa laser sisitemu nigice cyingenzi kigira ingaruka kumiterere yacyo n'imbaraga za pulse. Muguhindura ikigezweho, imiterere yinkuru ya Laser irashobora guhinduka, bityo igira ingaruka kubisohoka byingufu.

3. Gusaba Laser ingufu

Ingano ya Laser Pulse ingufu igena ibyo ikwiranye mumirima itandukanye. Porogaramu zimwe zisanzwe zirimo:

①Gutunganya ibintu:
Muri Laser gusunika, gukata, no gushushanya, imbaraga za pulse birashobora kugenzurwa neza kugirango bigerweho neza kandi bihanitse. Ingufu zo hejuru zikwiranye no gutunganya ibikoresho by'icyuma, mugihe impimbaro yo hasi ikoreshwa mu kuvura neza.

②Gusaba Ubuvuzi:
Abapakiye barangije bakoreshwa cyane mu rwego rw'ubuvuzi, cyane cyane kubaga Laser, ubuvuzi, no kuvura amajwi. Kurugero, abapakiyeri barwaye ingufu nyinshi barashobora kwibanda ku mbaraga za laser yumurongo wihariye hejuru yuburebure bwo gukurura amarangi cyangwa kuvura amaso.

③Lidar na kure yunvikana:
Ikoranabuhanga rya Lidar ryishingikirije kuri pulses ndende ya pulse kugirango rike kandi zitekereze. Mu gukurikirana ibidukikije, gutwara ibinyabiziga byigenga, na Drone Kugenzura, ubunini bw'ingufu bugira ingaruka mu buryo butaziguye intera no gukemura gahunda ya Lidar.

④Ubushakashatsi bwa siyansi:
Abashakashatsi ba Pulsers nabo bagira uruhare runini mubushakashatsi muri fiziki, chimie, na biologiya. Mu kugenzura neza ingufu za letse, abahanga mu bya siyansi bashobora gukora neza muri Laser-yasunitseho, kwihuta kwihuta, n'ubushakashatsi bwa laser.

4. Uburyo bwo kongera ingufu za pulse

Uburyo Rusange bwo kongera ingufu za Laser Pulse harimo:

①Wunguke uburyo bwo hagati:
Muguhitamo uburyo bukwiye no guhitamo igishushanyo mbonera cya laser cavity, ibisohoka imbaraga za laser birashobora kwiyongera.

②Interuro-yibanze ya laser:
Amplifiers nyinshi zirashobora kongera buhoro buhoro imbaraga za laser kugirango zujuje ibisabwa na porogaramu zitandukanye.

③Kongera gutwara ubugari bwa none cyangwa pulse:
Guhindura ibinyabiziga bya laser ubugari cyangwa pulse birashobora kuvamo imbaraga nini.

④Ikoranabuhanga rya Pulse:
Gukoresha tekinike ya Pulse, igihembo cya pulse kirashobora kugabanywa, kongera imbaraga zayo no kurekura imbaraga nyinshi mugihe gito.

5. UMWANZURO

Ingufu za Laser Pulse nicyitegererezo cyingenzi kigira uruhare rutaziguye imikorere no gukoresha laser mumirima itandukanye. Hamwe niterambere ryakomeje gukorwa tekinoroji ya Laser, abahise bamaze gupakira bazagira porogaramu nini munganda nyinshi. Duhereye ku rugero rwo kwishima kwa kure no kuvura kwa muganga, umusaruro mwinshi w'ingufu za Lases ufungura bishoboka. Gusobanukirwa imyumvire yibanze yingufu hamwe nibibazo byayo birashobora gufasha gukora ubushakashatsi bwa siyansi mugihe ushushanya kandi ugashyira mubikorwa sisitemu ya laser.
