Guhuza guhuza tekinoroji ya ultrashort pulse

Kubububasha bukomeye ultrashort pulse laser, itanga agaciro gakomeye mubushakashatsi bwa siyanse, umusaruro winganda nubuzima bwa biomedical.Sisitemu isanzwe ya coherent ihuza tekinoroji ya ultrashort pulse yerekanwa nkigishushanyo 1.

                                                           Igishushanyo 1 Guteganya guhuza / gutandukanya uburyo

Imbuto ya Laser izagabanywa mubice byinshi, hanyuma imbaraga zayo zizongerwamo imbaraga na AMP, ibice byose bigabanijwe bizahurira hamwe kugirango bizamure imbaraga nimbaraga.Mu rwego rwo kwirinda ingaruka zidafite umurongo, tekinoroji ya CPA izakoreshwa mu kwagura imbuto ya laser pulse mbere yo kongera ingufu, hanyuma kugirango ihagarike ubugari bwa pulse.Hariho uburyo butatu bwo kugera kubintu bihuza ultrashort pulse: guhuza umwanya uhuza guhuza, kugabana-pulse amplification (DPA), hamwe na pulse stack.

Kubyerekeranye no guhuza umwanya uhuza (ishusho 1 (a)), tekinike yibanze ni kimwe na laser ikomeza.Imbuto ya Laser igabanijwemo ibice, buri gice kimwe cyongerewe imbaraga na moderi ya moderi na amplifier hanyuma amaherezo igahuza nkimwe.

Inzira ya kabiri ni DPA (ishusho 1 (b)) igabanya impiswi ya laser muri buri cyiciro cya laser gitandukanijwe kandi ntigire ingaruka kuri buriwese.Urutonde rwa lazeri ruzahurira muri laser pulse kugirango izamure imbaraga zumusaruro usohoka.

Indwara ya pulse (ishusho 1 (c)) irashobora gukora impiswi nyinshi zishira mumitsi imwe ishobora kugerwaho na GTI na SND (stack-na-dump).

Ni mugihe kimwe icyarimwe havumbuwe guhuza ikorana buhanga hamwe na lazeri, ibyo bikaba byageze ku ntera ishimishije kuri 10.3kw ultra-yihuta ya fibre laser coherent ihuza hamwe na 100-imiyoboro minini ya fibre laser coherent ihuza, ikanamenya agaciro kayo muguhindura laser frequency, laser radar na laser kuyobora inyenyeri.Gukomeza kuvugurura tekinoroji ya laseri itanga isoko rishya ryumucyo kugirango uhuze, mubisubizo, kuzamuka kwumucyo uturuka kumucyo gushingira kumikoreshereze ihuza ikoranabuhanga.

Ibisobanuro byinshi byibicuruzwa, urashobora kuza gusura urubuga rwacu:
