Galasi Lowala la Mkuwa Loziziritsidwa ndi Madzi Lozungulira

Galasi Lowala la Mkuwa Loziziritsidwa ndi Madzi Lozungulira

Galasi lowala la mkuwa loziziritsidwa ndi madzi ndi chinthu chowala chomwe chimagwira ntchito motsatira mfundo ya kuwala. Limawongolera kuwala kwa laser komwe kumachitika mbali zosiyanasiyana kuti lithe kutumiza ndi kuyang'ana kwambiri. Kapangidwe kophatikizana koziziritsira madzi kamalola kugwira ntchito kwamphamvu kwambiri, kumawonjezera nthawi yogwira ntchito ya galasi, kumachepetsa kuchuluka kwa nthawi yolisinthira, komanso kumachepetsa ndalama zosamalira, zomwe zimapangitsa kuti likhale loyenera kugwiritsa ntchito kilowatts ndi laser yoposa ma kilowatts.

Zinthu ndi Njira

Galasili limapangidwa kuchokera ku substrate yamkuwa yokhala ndi mphamvu yotenthetsera yoposa 400 W/(m·K), yomwe imachotsa kutentha komwe kumapangidwa ndi kuwala kwa laser mwachangu. Pamodzi ndi makina oziziritsira madzi, izi zimatsimikizira kuti kutentha kuli bwino, kupewa kusintha kwa pamwamba kapena kuwonongeka kwa utoto. Mabaibulo ena amagwiritsa ntchito substrate ya nickel-copper alloy (NiCu) kuti awonjezere mphamvu zamakanika komanso kukana dzimbiri.

Pamwamba pa kuwala pamakhala potembenuza diamondi kapena kulumikiza molondola, zomwe zimapangitsa kuti pamwamba pakhale chithunzi cha λ/4 PV (@633 nm) ndi mtundu wa pamwamba pa 20/10 (kukanda/kukumba). Izi zimatsimikizira kukhazikika kwa gawo la kuwala kowala komanso kugwirizana ndi zofunikira zowongolera kuwala kwa lasers za ulusi ndi solid state. Chophimba chagolide cholimba (nthawi zambiri chimakhala chakuda cha 0.1–1 μm) chimayikidwa pa substrate yopukutidwa, zomwe zimapangitsa kuti kuwala kuwoneke bwino >99.5% (@10.6 μm) komanso kukana kukanda bwino.

Chophimba Chowala Chachitsulo Chowonjezera, Kuwunikira >99.5% pa 10.6μm

(Dziwani: X-axis imayimira kutalika kwa mafunde mu ma micrometer, Y-axis imayimira kuchuluka kwa kuwunikira.)

Kapangidwe Koziziritsira Madzi

Mayendedwe oziziritsira amaikidwa mkati mwa galasi. Madzi ozungulira kapena choziziritsira chapadera chimachotsa kutentha, zomwe zimakweza mphamvu yogwiritsira ntchito laser kufika pa 20–40 kW. Mitundu yosankhidwa imaphatikizapo ma circuits odziyimira pawokha oziziritsira nkhope ya galasi ndi maziko oikira, zomwe zimapangitsa kuti kutentha kuyende bwino komanso kugwira ntchito mosalekeza kwa maola mazana ambiri kapena kuposerapo.

Mapulogalamu

Galasi iyi ndi yoyenera ma laser a ulusi (1–40 kW) ndi ma laser a CO₂ omwe amagwira ntchito pa 10.6 μm ndi ma wavelengths apafupi ndi infrared, zomwe zimakwaniritsa zofunikira pakukonza bwino komanso kokhazikika kwa chitsulo chosapanga dzimbiri, zitsulo zotayidwa, ndi zipangizo zina. Imagwiritsidwa ntchito kwambiri pakuphimba ma cladding a laser, kupanga zowonjezera, kusintha kwa pamwamba pa laser, kupanga ma bandi a laser, kutentha kwa laser, ndi njira zina zokhudzana nazo.
