Eriri laser.
Laser eriri na-enye ụzọ dị ọnụ ala iji gbanwee ìhè nke laser semiconductor ike dị elu. Ọ bụ ezie na optics multiplexing wavelength nwere ike ịgbanwe laser semiconductor na-enwu nke ọma ka ọ bụrụ nke na-enwu enwu, nke a na-abịa na mmụba nke obosara spectral na mgbagwoju anya fotomechanical. Laser fiber egosila na ọ dị irè karịsịa na ntụgharị ìhè.

Eriri ndị e ji ihe mkpuchi abụọ mee nke e tinyere n'ime afọ 1990, site n'iji otu ụdị isi nke e ji ihe mkpuchi multimode gbaa gburugburu, nwere ike itinye lasers multimode semiconductor pump lasers nke nwere ike dị elu, nke dị ọnụ ala karịa n'ime eriri ahụ, na-emepụta ụzọ ka mma iji gbanwee lasers semiconductor dị ike ka ọ bụrụ isi iyi ọkụ na-enwu gbaa. Maka eriri ytterbium-doped (Yb), ọkpọkọ ahụ na-akpali eriri absorption sara mbara nke dị na 915nm, ma ọ bụ eriri absorption dị warara nke dị nso na 976nm. Ka ogologo oge mgbapụta na-eru nso ogologo oge nke laser eriri ahụ, ihe a na-akpọ quantum deficit na-ebelata, na-eme ka arụmọrụ dịkwuo elu ma na-ebelata oke okpomọkụ mkpofu nke kwesịrị ka a gbasaa.

Eriri laserna lasers steeti siri ike nke diode na-agbapụta ma na-adabere na mmụba nke ìhè nkelaser diodeN'ozuzu, ka ìhè nke laser diode na-akawanye mma, ike nke laser ha na-agbapụta na-abawanyekwa. Mmezi ìhè nke laser semiconductor na-akwalite mgbanwe ìhè dị irè karị.

Dịka anyị tụrụ anya ya, ìhè oghere na spectral ga-adị mkpa maka sistemụ ndị ga-eme n'ọdịnihu nke ga-eme ka obere mkpọtụ quantum deficit pumping maka atụmatụ nnabata dị warara na lasers siri ike, yana atụmatụ ojiji ogologo oge dị ukwuu maka ngwa laser semiconductor kpọmkwem.

Ahịa na ngwa

Ọganihu dị na laser semiconductor ike dị elu emeela ka ọtụtụ ngwa dị mkpa kwe omume. Ebe ọ bụ na ọnụ ahịa kwa watt nke laser semiconductor ike dị elu ebelatala nke ukwuu, laser ndị a na-anọchi teknụzụ ochie ma na-eme ka ụdị ngwaahịa ọhụrụ dị.

Ebe ọnụ ahịa na arụmọrụ ya na-akawanye mma karịa ugboro iri kwa afọ iri, laser semiconductor nwere ike dị elu emebiela ahịa ahụ n'ụzọ ndị a na-atụghị anya ya. Ọ bụ ezie na ọ siri ike ịkọ amụma maka ojiji n'ọdịnihu na nkenke, ọ na-enyekwa aka n'ileghachi anya azụ n'ime afọ iri atọ gara aga iji chee echiche banyere ihe ga-eme n'ime afọ iri na-abịa (lee eserese nke 2).
