Yambitsani gwero laposachedwa la kuwala kwa laser lamphamvu kwambiri

Fotokozani zatsopano zamphamvu kwambirigwero la kuwala kwa laser

Magwero atatu apakati a kuwala kwa laser amaika mphamvu yayikulu mu ntchito zamagetsi amphamvu kwambiri

Mu gawo la ntchito za laser zomwe zimatsata mphamvu yayikulu komanso kukhazikika kotheratu, mayankho okwera mtengo kwambiri a pampu ndi laser akhala akufunidwa kwambiri ndi makampani. Masiku ano, tikupereka zinthu zitatu zazikulu zomwe zimasiyana kwambiri pankhani ya magwiridwe antchito ndi kudalirika: magwero a kuwala kwa laser opompedwa ndi single-mode, magwero a kuwala kwa laser opompedwa ndi multi-mode, ndi 1550nm continuous fiber lasers (CW laser), zomwe zimakuthandizani kuchita khama kwambiri pa kafukufuku wasayansi ndi ntchito zamafakitale.

Gwero la kuwala kwa laser lopopedwa ndi njira imodzi

Sikuti ndi gwero lokha la kuwala komanso "mtima wamphamvu" wa makina omwe amafunidwa kwambiri. Amagwiritsa ntchito njira imodzi yokhalaser ya semiconductorndi grating ya FBG yokhazikika pa mafunde, yomwe imatha kutulutsa laser yokhala ndi mafunde okhazikika komanso mphamvu yamphamvu. Yokonzedwa bwino kuti igwiritsidwe ntchito molimbika monga ma amplifiers amphamvu kwambiri komanso mode-lockedlaser ya ulusiTikudziwa bwino za kuopsa kwa kuwala kwa ASE komwe kumapangidwa ndi ulusi wochita kuwala ku gwero la pampu. Chifukwa chake, tapanga njira yodzitetezera pampu kuti tipange chingwe cholimba choteteza kuti makina anu azigwira ntchito bwino.

2. Gwero la kuwala kwa laser lopopedwa ndi multimode

Lowetsani mphamvu yamphamvu mulaser yamphamvu kwambirindi ma amplifiers. Ili ndi laser yopompedwa ndi chubu chimodzi yogwira ntchito bwino kwambiri, yomwe imapangitsa kuti pakhale bwino pakati pa mphamvu yayikulu ndi kuwala kwakukulu. Pakati pake pali makina owongolera anzeru ophatikizidwa ndi microprocessor yapamwamba, yophatikizidwa ndi ma circuits a ATC (Automatic Temperature Control) ndi ACC/APC (Automatic current/Power Control), kuti zitsimikizire kuti kutulutsa kwake kuli kokhazikika kwambiri. Ntchitoyi ndi yosavuta komanso yothandiza, ndipo imathandizira ma interface olumikizirana ndi mapulogalamu owongolera, zomwe zimapangitsa kuti kuphatikiza ndi kulamulira kodziyimira pawokha kukhale kosavuta.

3.1550nmLaza ya CW

Kutengera ndi gulu la "chitetezo cha maso", tikutsegula mutu watsopano pakugwiritsa ntchito mphamvu zambiri. Pogwiritsa ntchito kapangidwe kophatikizana ndi ulusi wonse, chifukwa cha ukadaulo wopopera ulusi wovala kawiri, imatha kutulutsa ma lasers amphamvu kuyambira 200mW mpaka 10W. Dongosolo lowongolera lozikidwa pa ma microprocessor limatsimikizira kukhazikika kwake kwa nthawi yayitali komanso mawonekedwe osakonza. Gulu lakutsogolo la chitsanzo cha desktop lili ndi chophimba cha LCD, chomwe chimatha kuyang'anira magawo ofunikira monga mphamvu ndi kutentha komanso chidziwitso cha alamu nthawi yeniyeni. Mawonekedwe ake ndi omveka bwino ndipo ntchitoyo ndi yosavuta kuyidziwa. Nthawi yomweyo, timaperekanso njira zosinthira zophatikizira, zomwe zimathandiza kwambiri kuphatikiza makina anu.

Kaya ndi kufunafuna kukhazikika kwathunthu pakufunika kwa kupopera kapena kufunikira kwa kutulutsa kwa laser yamphamvu kwambiri komanso chitetezo cha maso chapamwamba, mitundu yathu yazinthu zitha kupereka mayankho aukadaulo komanso odalirika.
