Laser ya fibre.
Fiber laser itanga uburyo buhendutse bwo guhindura urumuri rwa laser za semiconductor zifite imbaraga nyinshi. Nubwo optique ya wavelength multiplexing ishobora guhindura laser za semiconductor zifite urumuri ruto cyane zikajyamo iz’urumuri rwinshi, ibi biza ku giciro cy’ubwiyongere bw’ubugari bwa spectral n’ubuhanga bwo gufotora. Fiber lasers zagaragaye ko zifite akamaro kanini mu guhindura urumuri.

Imigozi ibiri yatangijwe mu myaka ya za 1990, ikoresheje igice cy’imbere cy’uburyo bumwe kizengurutswe n’ingufu za multimode, ishobora kwinjiza neza imigozi ya multimode semiconductor pump lasers ifite imbaraga nyinshi kandi ihendutse muri iyo migozi, bigatuma habaho uburyo buhendutse bwo guhindura imigozi ya high-power semiconductor lasers ikaba isoko y’urumuri rwinshi. Ku migozi ya ytterbium-doped (Yb), iyo migozi ikora umugozi munini wo kwinjizamo uherereye kuri 915nm, cyangwa umugozi muto wo kwinjizamo hafi ya 976nm. Uko umugozi wo kwinjizamo ugenda wegereza umugozi ugenda ushira wa fibre laser, icyitwa quantum deficit kiragabanuka, bigatuma imikorere irushaho kuba myiza kandi bikagabanya ubushyuhe bugomba gukurwaho.

Lazeri za fibrena lasers za solid-state zikoreshwa na diode zombi zishingira ku kwiyongera k'urumuri rwalaser ya diodeMuri rusange, uko urumuri rwa laser za diode rukomeza kwiyongera, imbaraga za laser zitanga nazo ziyongera. Kunoza urumuri rwa laser za semiconductor bikunze gutuma urumuri ruhinduka neza kurushaho.

Nkuko tubyiteze, urumuri rw’ahantu n’urumuri ruzakenerwa kuri sisitemu z’ejo hazaza zizafasha kohereza ubusembwa buke bwa quantum kugira ngo habeho uburyo bwo kwinjiza ibintu mu buryo buciriritse muri laser za state solid-state, ndetse no gukoresha neza uburebure bw’umurambararo mu gukoresha laser za semiconductor mu buryo butaziguye.

Isoko n'ikoreshwa

Iterambere mu mikoreshereze ya laser za semiconductor zifite imbaraga nyinshi ryatumye habaho byinshi by'ingenzi. Kubera ko ikiguzi cya watt y'ubushyuhe kuri buri watt ya laser za semiconductor zifite imbaraga nyinshi cyagabanutse cyane, izi laser zombi zisimbura ikoranabuhanga rishaje kandi zigatuma habaho ibyiciro bishya by'ibicuruzwa.

Kubera ko ikiguzi n'imikorere byazamutse inshuro zirenga 10 buri myaka icumi, laser za semiconductor zifite imbaraga nyinshi zahungabanyije isoko mu buryo butunguranye. Nubwo bigoye guhanura ikoreshwa ry'ejo hazaza mu buryo bunonosoye, ni byiza kandi gusubiza amaso inyuma mu myaka mirongo itatu ishize kugira ngo utekereze ku mahirwe yo mu myaka icumi iri imbere (reba Ishusho ya 2).

Ubwo Hall yerekanaga imirasire ya semiconductor mu myaka irenga 50 ishize, yatangije impinduramatwara mu ikoranabuhanga. Kimwe n'amategeko ya Moore, nta muntu n'umwe washoboraga guhanura ibyagezweho by'imirasire ya semiconductor ikomeye cyane byakurikiyeho hamwe n'udushya twinshi dutandukanye.

Ahazaza ha laser za semiconductor
Nta mategeko shingiro ya fiziki agenga izi ntambwe, ariko iterambere ry’ikoranabuhanga rikomeje rishobora gukomeza iri terambere rikomeye mu bwiza. Lazeri za semiconductor zizakomeza gusimbura ikoranabuhanga gakondo kandi zizakomeza guhindura uburyo ibintu bikorwamo. Icy'ingenzi kurushaho kugira ngo ubukungu burusheho gutera imbere, lazeri za semiconductor zikomeye nazo zizahindura ibishobora gukorwa.
