Laser ya ulusi.
Ma laser a fiber amapereka njira yotsika mtengo yosinthira kuwala kwa ma laser a semiconductor amphamvu kwambiri. Ngakhale kuti ma wavelength multiplexing optics amatha kusintha ma laser a semiconductor omwe ndi owala pang'ono kukhala owala, izi zimachitika chifukwa cha kuchuluka kwa spectral width ndi photomechanical complexity. Ma laser a fiber atsimikizira kuti ndi othandiza kwambiri pakusintha kuwala.

Ulusi wopangidwa ndi double-clad womwe unayambitsidwa m'ma 1990, pogwiritsa ntchito single-mode core yozunguliridwa ndi multimode cladding, ukhoza kuyambitsa bwino ma multimode semiconductor pump lasers amphamvu kwambiri komanso otsika mtengo mu ulusi, zomwe zimapangitsa njira yotsika mtengo yosinthira ma high-power semiconductor lasers kukhala magwero owala kwambiri. Pa ulusi wa ytterbium-doped (Yb), pampu imakopa gulu lalikulu loyamwa lomwe lili pakati pa 915nm, kapena gulu loyamwa locheperako pafupi ndi 976nm. Pamene kutalika kwa mafunde kuyandikira kutalika kwa mafunde a fiber laser, chomwe chimatchedwa quantum deficit chimachepa, zomwe zimapangitsa kuti ntchito ikhale yogwira mtima kwambiri ndikuchepetsa kutentha komwe kumafunika kutayidwa.

Ma laser a ulusindi ma lasers a solid-state opangidwa ndi diode amadalira kuwonjezeka kwa kuwala kwalaser ya diodeKawirikawiri, pamene kuwala kwa ma diode lasers kukupitirira kukula, mphamvu ya ma lasers omwe amapompa imakulanso. Kuwongolera kuwala kwa ma semiconductor lasers kumalimbikitsa kusintha kwa kuwala bwino.

Monga momwe tikuyembekezerera, kuwala kwa malo ndi ma spectral kudzafunika pa machitidwe amtsogolo omwe adzalola kupopera kwa quantum deficit kochepa kuti zinthu zochepetsera kuyamwa zikhale zochepa mu ma laser olimba, komanso njira zogwiritsiranso ntchito ma wavelength ochuluka kwambiri pogwiritsira ntchito ma laser a semiconductor mwachindunji.

Chithunzi 2: Kuwala kowonjezereka kwa mphamvu yayikuluma laser a semiconductorimalola mapulogalamu kukulitsidwa

Msika ndi kugwiritsa ntchito

Kupita patsogolo kwa ma laser a semiconductor amphamvu kwambiri kwapangitsa kuti ntchito zambiri zofunika zitheke. Popeza mtengo wa watt pa kuwala kwa ma laser a semiconductor amphamvu kwambiri wachepetsedwa kwambiri, ma laser amenewa amalowa m'malo mwa ukadaulo wakale ndikupangitsa kuti mitundu yatsopano ya zinthu igwire ntchito.

Popeza mtengo ndi magwiridwe antchito zikukwera nthawi zoposa 10 pazaka khumi zilizonse, ma laser amphamvu kwambiri a semiconductor lasers asokoneza msika m'njira zosayembekezereka. Ngakhale kuti n'kovuta kulosera momwe ntchito zamtsogolo zidzagwiritsidwire ntchito molondola, ndikofunikanso kuyang'ana m'mbuyo m'zaka makumi atatu zapitazi kuti tiganizire zomwe zingatheke m'zaka khumi zikubwerazi (onani Chithunzi 2).

Pamene Hall adawonetsa ma laser a semiconductor zaka zoposa 50 zapitazo, adayambitsa kusintha kwaukadaulo. Monga Moore's Law, palibe amene akanatha kuneneratu kupambana kwabwino kwa ma laser a semiconductor amphamvu kwambiri omwe adatsatira ndi mitundu yosiyanasiyana yazatsopano.

Tsogolo la ma laser a semiconductor
Palibe malamulo oyambira a fizikisi omwe amalamulira kusinthaku, koma kupita patsogolo kwaukadaulo kungapangitse kuti chitukukochi chikhale chokongola kwambiri. Ma laser a semiconductor apitilizabe kulowa m'malo mwa ukadaulo wachikhalidwe ndipo asintha kwambiri momwe zinthu zimapangidwira. Chofunika kwambiri pakukula kwachuma, ma laser a semiconductor amphamvu kwambiri adzasinthanso zomwe zingapangidwe.
