Murakaza neza kuri Ruijie Laser

nigute fibre laser ikora? –Lisa wo muruganda rwa Ruijie fibre laser

Fibre ikoreshwa nkibikoresho byo hagati ya laser yawe izaba yarakuwe mubintu bidasanzwe-isi, kandi uzasanga akenshi ari Erbium.Impamvu ibi bikorwa nuko urwego rwa atom rwibintu byisi bifite urwego rwingufu zingirakamaro cyane, rutanga isoko ya diode ya laser pompe ihendutse gukoreshwa, ariko ibyo bizatanga umusaruro mwinshi mwinshi.

Kurugero, mugukata fibre muri Erbium, urwego rwingufu zishobora gukurura fotone ifite uburebure bwa 980nm yangirika kugeza meta-ihagaze ihwanye na 1550nm.Icyo bivuze ni uko ushobora gukoresha isoko ya pompe ya laser kuri 980nm, ariko ugakomeza kugera kumurongo wo hejuru, ingufu nyinshi hamwe nimbaraga za laser beam ya 1550nm.

Atome ya Erbium ikora nk'icyuma cya laser muri fibre ikozwe, kandi fotone isohoka iguma muri fibre yibanze.Kurema akavuyo fotone ikomeza gufatwa, ikintu kizwi nka Fibre Bragg Grating yongeyeho.

Gushimira Bragg ni igice cyikirahure gifite imirongo muri yo - niho hagaragazwa indangagaciro.Igihe icyo aricyo cyose urumuri rwanyuze kumupaka hagati yurutonde rumwe rwakurikiyeho, urumuri ruto rusubizwa inyuma.Byibanze, Bragg Grating ituma fibre laser ikora nkindorerwamo.

Lazeri ya pompe yibanda kumyenda yicaye hafi ya fibre, kuko fibre fibre ubwayo ari nto cyane kuburyo idafite lazeri yo mu rwego rwo hasi yibandaho.Mugusunika lazeri mukuzenguruka kwimbere, lazeri isunikwa imbere, kandi burigihe iyo inyuze mumutwe, byinshi kandi byinshi mumucyo wa pompe byinjizwa ninturusu.
