Ua ʻōlelo ʻo BWT i ke kumumanaʻo o ka hoʻonohonoho spatial spatial (DSBC) a hōʻoia i ka pololei o DSBC ma o ka hoʻokolohua ʻana i ke kumu punawai kilowatt-level.I kēia manawa, ua hoʻonui ʻia ka mana o kahi paipu hoʻokahi i 15W-30W@BPP≈5-12mm*mrad a ʻo ka pono electro-optical he> 60%, e hiki ai i ka puna wai mana kiʻekiʻe i hui pū ʻia me ka fiber output e mālama kiʻekiʻe. ka puka ʻana o ka mālamalama i ka wā e hoʻemi ana i ka leo, Hiki ke hoʻemi i ke kaumaha a hoʻomaikaʻi i ka pono hoʻololi electro-optical.

Ke hoʻohana nei i ka chip o kēia manawa, ua ʻike ʻo BWT i kahi puna puna me ke anawaena kumu o 135μm NA0.22 fiber-coupled output 420W wavelength-locked ma 976nm, quality ≈ 500g;a me ke anawaena koʻikoʻi o 220μm NA0.22 fiber i hui pū ʻia me ka puka 1000W hoʻokahi hawewe lōʻihi 976nm (a i ʻole 915nm), maikaʻi ≈ 400g puna puna.

I ka wā e hiki mai ana, me ka hoʻomaikaʻi ʻana o ka ʻālohilohi semiconductor chip a me ka electro-optical efficiency, māmā a me nā puna wai mana kiʻekiʻe e pāʻani i kahi hana i hiki ʻole ke hoʻololi ʻia i ka hana ʻana i nā kumu kukui laser fiber liʻiliʻi, a e hoʻoikaika ikaika i ka hoʻomohala ʻana. o na noi hana.

Ua ulu wikiwiki nā laser fiber ma muli o ka maikaʻi o ka beam maikaʻi a me ka hiki ke hoʻonui i ka mana (fiber combiners).I kēia mau makahiki i hala iho nei, ua kaupalena ʻia nā laser fiber fiber single-mode e TMI (transverse mode instability) a me nā hopena SRS, a ua kaupalena ʻia ka mana o ka semiconductor direct pumping fiber laser oscillators i 5kW.
[1].Hoʻopau ʻia ka mea hoʻonui laser ma 10kW
[2].ʻOiai hiki ke hoʻonui ʻia ka mana hoʻopuka ma ka hoʻonui ʻana i ke anawaena koʻikoʻi, ua emi pū ka maikaʻi o ka beam puka -1.Eia nō naʻe, ʻo ke koi no ka hoʻomaikaʻi ʻana i ka ʻōlinolino o nā kumu puna semiconductor e koi mau nei.
ʻO nā koi no ka maikaʻi o ka beam i nā noi hana ʻoihana ʻaʻole pono ke ʻano hoʻokahi.I mea e hoʻonui ai i ka mana o ka fiber-fiber, ua ʻae ʻia kekahi mau ʻano haʻahaʻa haʻahaʻa.A hiki i kēia manawa, kakaikahi-mode single-fiber a me ka beam-combined multi-mode laser light source e pili ana i ka 976nm pumping of more than 5kW Me nā noi puʻupuʻu (ʻoi aku ka ʻoki ʻana a me ka hoʻopili ʻana i nā mea metala), ka hana ʻana i nā kumu puna mana kiʻekiʻe. he pūʻali koa.
ʻOi aku ka liʻiliʻi, māmā a paʻa
ʻO ka pilina ma waena o ka BPP chip semiconductor a me ka mālamalama o ke kumu puna
ʻEkolu mau makahiki i hala aku nei, ʻo ka ʻōlinolino o nā chips 9xxnm ka hapa nui ma ke kiʻekiʻe o 3W/mm*mrad@12W-100μm ākea ākea & 2W/mm*mrad@18W-200μm ākea ākea.Ma muli o ia mau ʻāpana, loaʻa ka BWT i 600W a me 1000W 200μm NA0.22 fiber-coupled output-1.
I kēia manawa, ua loaʻa ka ʻōlinolino o 9xxnm chips 3.75W/mm*mrad@15W-100μm strip width & 3W/mm*mrad@30W-230μm strip width, a ua mālama ʻia ka pono electro-optical ma kahi o 60%.
Wahi a ke kumumanaʻo o ka hoʻonohonoho spatial ākea [6], ua helu ʻia e like me ka awelika fiber coupling efficiency o 78% (laser emission mai ka chip a fiber coupling output: single-wavelength spatial beam combining and polarization beam e hui pū ana me ka VBG), a ua manaʻo ʻia e hana ka chip ma ka mana kiʻekiʻe loa ( He ʻokoʻa ka chip BPP i nā ʻano ʻokoʻa), ua hōʻuluʻulu mākou i kahi palapala ʻikepili penei:

* ʻO ka ʻālohilohi chip VS ʻokoʻa ʻokoʻa ʻokoʻa anawaena Fiber Coupling Output Power

Hiki ke ʻike ʻia mai ka kiʻi ma luna aʻe i ka wā e loaʻa ai kahi fiber (ka anawaena kumu a me NA) i kahi mana hoʻohui pū ʻana, no nā ʻāpana me nā ʻōlinolino like ʻole, ʻokoʻa ka helu o nā pahu, a me ka nui a me ke kaumaha o ka puna puna. ʻokoʻa nō hoʻi.No nā koi ʻana o ka laser fiber, inā koho ʻia ke kumu puna i hana ʻia i nā ʻāpana i luna me nā ʻōlino like ʻole, ʻokoʻa loa ke kaumaha a me ka nui o ka laser fiber o ka mana like, a ʻo ka hoʻonohonoho ʻana o ka ʻōnaehana hoʻoluʻu wai. ʻokoʻa loa.
ʻO ka hana kiʻekiʻe, ka liʻiliʻi a me ka paona māmā nā ʻano hiki ʻole i ka hoʻomohala ʻana i nā kumu kukui laser e hiki mai ana (inā he diode lasers, solid-state lasers a i ʻole fiber lasers), a me ka ʻōlinolino, ka pono a me ka mana o nā ʻāpana semiconductor e pāʻani i ke kuleana koʻikoʻi i loko. .
Māmā, ʻōlinolino kiʻekiʻe, kumu puna mana kiʻekiʻe
I mea e hoʻololi ai i ka fiber combiner, ua koho mākou i nā kikoʻī kikoʻī maʻamau: 135μm NA0.22 a me 220μm NA0.22.Hoʻohana ka hoʻolālā optical o nā puna wai ʻelua i ka hoʻonohonoho spatial ākea a me ka hui ʻana o ka polarization beam.
Ma waena o lākou, hoʻohana ka 420WLD i ka 3.75W / mm * mrad@15W chip a me 135μm NA0.22 fiber, a loaʻa iā VBG ka lōʻihi o ka hawewe, e hoʻokō ana i nā koi o 30-100% paʻa hawewe, a ʻo ka hana electro-optical he 41% .Hana ʻia ke kino LD me nā mea alumini alumini a me ka hana sandwich [5].Kaʻana like nā ʻāpana o luna a me lalo i ke kahawai hoʻoluʻu wai, kahi e hoʻomaikaʻi ai i ka hoʻohana ʻana i ka lewa.Hōʻike ʻia ka hoʻonohonoho kiko māmā, spectrum a me ka mana (ka mana i ka fiber) i ke kiʻi:

Ua koho mākou i 6 mau LD no ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa a me nā hoʻokolohua haʻalulu.ʻO ka ʻikepili hōʻike penei:
