Lazeri.
Fibre ya fibre itanga uburyo buhendutse bwo guhindura urumuri rwinshi rwa semiconductor laseri.Nubwo uburebure bwumurongo wa optique bushobora guhindura lazeri nkeya-yumucyo wa semiconductor lazeri ukayangana, ibi biza kubiciro byubwiyongere bwubugari bwikigereranyo hamwe nuburemere bwamafoto.Lazeri ya fibre yerekanye ko ifite akamaro kanini muguhindura umucyo.

Fibre yambaye kabiri yatangijwe mu myaka ya za 90, ikoresheje intoki imwe yuburyo bumwe ikikijwe na multimode yambaye, irashobora kwinjiza neza imbaraga-zohejuru, zihenze cyane za multimode semiconductor pomp lazeri muri fibre, bigashyiraho uburyo bwubukungu bwo guhindura lazeri zifite ingufu nyinshi. mu mucyo.Kuri fibre ya ytterbium (Yb), pompe ishimisha umurongo mugari winjiza hagati ya 915nm, cyangwa umurongo muto wo kwinjiza hafi ya 976nm.Mugihe uburebure bwa pompe bwegereje uburebure bwumurambararo wa fibre laser, icyo bita kwant defisit iragabanuka, bigakorwa neza kandi bikagabanya ubushyuhe bwimyanda igomba gukwirakwizwa.

Lazerina diode-pompe ikomeye-leta ya laseri zombi zishingiye kubwiyongere bwurumuri rwadiode laser.Muri rusange, uko urumuri rwa diode rukomeza gutera imbere, imbaraga za lazeri bavoma nazo ziriyongera.Umucyo utezimbere ya semiconductor laseri ikunda guteza imbere urumuri rwiza.

Nkuko tubyitezeho, umucyo utagaragara hamwe nuburyo bugaragara bizakenerwa muri sisitemu zizaza zizafasha kwipompa nkeya ya pompe ya pompe kugirango igabanye ibintu bito cyane muri lazeri-ikomeye, kimwe nuburebure bwumurongo wogukoresha gahunda ya semiconductor laser ikoreshwa.

Isoko no gusaba

Iterambere muri power-semiconductor laseri yatumye ibintu byinshi byingenzi bishoboka.Kuva ikiguzi kuri watt ya power-semiconductor lazeri yagabanutse cyane, izo lazeri zombi zisimbuza tekinoroji ishaje kandi igafasha ibyiciro bishya.

Hamwe nigiciro hamwe nibikorwa bizamura inshuro zirenga 10 buri myaka icumi, lazeri zifite ingufu nyinshi za semiconductor zahungabanije isoko muburyo butunguranye.Mugihe bigoye guhanura ibizakurikiraho neza, biratwigisha kandi gusubiza amaso inyuma mumyaka mirongo itatu ishize kugirango utekereze ibishoboka mumyaka icumi iri imbere (reba Ishusho 2).

Igihe Hall yerekanaga lazeri ya semiconductor mu myaka irenga 50 ishize, yatangije impinduramatwara mu ikoranabuhanga.Kimwe n'Amategeko ya Moore, ntamuntu numwe washoboraga guhanura ibyagezweho nibyiza bya lazeri zifite ingufu nyinshi zikurikira hamwe nudushya dutandukanye.

Kazoza ka semiconductor laseri
Nta mategeko shingiro ya fiziki agenga iri terambere, ariko gukomeza iterambere ryikoranabuhanga birashoboka ko bizakomeza iryo terambere ryiza cyane.Laser ya Semiconductor izakomeza gusimbuza tekinoroji gakondo kandi izahindura uburyo ibintu bikorwa.Icy'ingenzi mu kuzamuka mu bukungu, laseri ifite ingufu nyinshi za semiconductor nayo izahindura ibishobora gukorwa.
