Fiber laser.
Fiber lasers imapereka njira yotsika mtengo yosinthira kuwala kwa ma lasers amphamvu kwambiri a semiconductor. Ngakhale kuwala kwa mafunde ophatikizika kwa mafunde amatha kusintha ma semiconductor lasers otsika kwambiri kukhala owala, izi zimabwera pamtengo wa kuchuluka kwa mawonekedwe a mawonekedwe ndi zovuta za photomechanical. Ma fiber lasers atsimikizira kukhala othandiza kwambiri pakusintha kowala.

Ulusi wovala kawiri womwe unayambika m'zaka za m'ma 1990, pogwiritsa ntchito njira imodzi yokha yozunguliridwa ndi multimode cladding, imatha kuyambitsa ma lasers apamwamba kwambiri, otsika mtengo a multimode semiconductor pump mu fiber, kupanga njira yotsika mtengo yosinthira ma lasers amphamvu kwambiri. ku magwero owala kwambiri. Pamanyuzi a ytterbium-doped (Yb), pampu imakondwera ndi bandi yayikulu yoyamwa yomwe ili pa 915nm, kapena bandi yocheperako pafupi ndi 976nm. Pamene mphamvu yopopera ikuyandikira kutalika kwa laser fiber laser, zomwe zimatchedwa quantum deficit zimachepetsedwa, kupititsa patsogolo mphamvu ndi kuchepetsa kutentha kwa zinyalala zomwe zimayenera kutayidwa.

Fiber lasersndi ma diode-pumped solid-state lasers onse amadalira kuwonjezeka kwa kuwala kwalaser diode. Nthawi zambiri, kuwala kwa ma lasers a diode kukupitilirabe, mphamvu zama lasers omwe amapopa nawonso zimawonjezeka. Kuwongolera kowala kwa ma semiconductor lasers kumalimbikitsa kutembenuka kowala bwino.

Monga momwe tikuyembekezera, kuwala kwa malo ndi mawonekedwe owoneka bwino kudzakhala kofunikira pamakina amtsogolo omwe apangitse kupopera kocheperako pang'ono kwa mawonekedwe ocheperako mu ma lasers olimba, komanso njira zogwiritsanso ntchito mafunde amphamvu a semiconductor laser application.

Market ndi ntchito

Kupita patsogolo kwa ma lasers amphamvu kwambiri a semiconductor kwapangitsa kuti ntchito zambiri zofunika zitheke. Popeza mtengo wa watt wowala wa ma laser amphamvu kwambiri a semiconductor wachepetsedwa mokulira, ma laser onsewa amalowetsa matekinoloje akale ndikupangitsa magulu atsopano.

Popeza mtengo ndi magwiridwe antchito zikupitilira kuwirikiza ka 10 pazaka khumi zilizonse, ma laser amphamvu a semiconductor asokoneza msika m'njira zosayembekezereka. Ngakhale kuli kovuta kulosera zam'tsogolo molunjika, ndizophunzitsanso kuyang'ana mmbuyo pazaka makumi atatu zapitazi kuti tiganizire zotheka zazaka khumi zikubwerazi (onani Chithunzi 2).

Hall atawonetsa ma semiconductor lasers zaka 50 zapitazo, adayambitsa kusintha kwaukadaulo. Monga Chilamulo cha Moore, palibe amene akananeneratu zakuchita bwino kwa ma lasers amphamvu kwambiri a semiconductor omwe adatsata ndi zatsopano zosiyanasiyana.

Tsogolo la semiconductor lasers
Palibe malamulo ofunikira afizikiki omwe amayang'anira kusinthaku, koma kupita patsogolo kwaukadaulo ndizotheka kupititsa patsogolo chitukuko chodabwitsachi. Ma laser a semiconductor apitilizabe kusintha ukadaulo wakale ndipo asinthanso momwe zinthu zimapangidwira. Chofunika kwambiri pakukula kwachuma, ma laser amphamvu kwambiri a semiconductor asinthanso zomwe zingapangidwe.
