Laser hoʻololi Q a me Laser MOPA

I nā makahiki i hala iho nei, ua ulu wikiwiki ka noi ʻana o nā laser fiber pulsed i ke kahua o ka mākaʻikaʻi ʻana i ka laser, i waena o nā noi i nā ʻoihana o nā huahana uila 3C, nā mīkini, nā meaʻai, nā ʻōpala, a me nā mea ʻē aʻe.

I kēia manawa, ʻo nā ʻano o nā laser fiber pulsed i hoʻohana ʻia i ka mākaʻikaʻi ʻana i ka laser ma ka mākeke me ka ʻenehana Q-switched a me ka ʻenehana MOPA.ʻO ka laser MOPA (Master Oscillator Power-Amplifier) ​​e pili ana i kahi hoʻolālā laser kahi i hoʻolele ʻia ai kahi oscillator laser a me kahi mea hoʻonui.I loko o ka ʻoihana, ʻo ka laser MOPA e pili ana i kahi mea kūʻokoʻa a ʻoi aku ka "naʻauao" nanosecond pulse fiber laser i haku ʻia me kahi kumu kumu semiconductor laser i alakaʻi ʻia e nā pulu uila a me ka fiber amplifier.Hōʻike ʻia kona "naʻauao" i ka laulā pulse puka e hiki ke hoʻoponopono kūʻokoʻa (kahi 2ns-500ns), a hiki ke kiʻekiʻe ke kiʻekiʻe e like me ka megahertz.ʻO ke kumu kumu kumu o ka Q-switched fiber laser ʻo ia ka hoʻokomo ʻana i kahi modulator poho i loko o ka lua oscillator fiber, kahi e hoʻopuka ai i kahi kukui pulse nanosecond me kahi ākea pulse ma o ka hoʻololi ʻana i ka nalowale o ka optical i loko o ka lua.

ʻO ke ʻano o loko o ka laser

ʻO ka ʻokoʻa o loko ma waena o ka MOPA fiber laser a me ka Q-switched fiber laser ka mea nui i nā ʻano hana like ʻole o ka hōʻailona kukui hua pulse.Hoʻokumu ʻia ka MOPA fiber laser pulse seed optical signal e ka uila pulse driving semiconductor laser chip, ʻo ia hoʻi, ua hoʻololi ʻia ka hōʻailona optical output e ka hōʻailona uila hoʻokele, no laila ikaika loa ia no ka hana ʻana i nā ʻāpana pulse like ʻole (ka laulā puʻupuʻu, pinepine pinepine. , Pulse waveform a me ka mana, etc.) Hoʻololi.Hoʻopuka ka pulse seed optical signal o ka Q-switched fiber laser i ka puka kukui pulsed ma o ka hoʻonui pinepine ʻana a i ʻole ka hōʻemi ʻana i ka nalowale o ka optical i loko o ka lua resonant, me kahi ʻano maʻalahi a me ka uku kumukūʻai.Eia nō naʻe, ma muli o ka mana o nā mea hoʻololi Q, loaʻa i nā ʻāpana pulse kekahi mau palena.

Hoʻokuʻu i nā ʻāpana optical

MOPA fiber laser output pulse laula hiki ke hoʻololi kūʻokoʻa.ʻO ka laula pulse o ka MOPA fiber laser he mea hiki ke hoʻokō (kahi 2ns～500 ns).ʻOi aku ka liʻiliʻi o ka laula pulse, ʻoi aku ka liʻiliʻi o ka wahi i hoʻopili ʻia i ka wela, a hiki ke loaʻa ka pololei o ka hoʻoponopono kiʻekiʻe.ʻAʻole hiki ke hoʻololi ʻia ka laula pulse puka o ka laser fiber Q-switched, a paʻa mau ka laulā pulse ma kahi waiwai paʻa ma waena o 80 ns a me 140 ns.ʻOi aku ka laulā o ka hoʻopaʻi pinepine ʻana o ka laser MOPA fiber.Hiki i ka re-frequency o ka laser MOPA ke hiki i ka puka kiʻekiʻe o MHz.'O ke alapine o ka hana hou 'ana ki'eki'e, 'o ia ho'i, hiki i ka MOPA ke mālama i nā hi'ohi'ona mana ki'eki'e ma lalo o nā kūlana alapine ki'eki'e.Hoʻopili ʻia ka laser fiber Q-switched e nā kūlana hana o ka hoʻololi Q, no laila ua haiki ka laina alapine puka, a hiki i ke alapine kiʻekiʻe ke hiki wale i ~ 100 kHz.

Hoʻolālā noi

Loaʻa i ka MOPA fiber laser kahi ākea hoʻoponopono hoʻololi.No laila, ma waho aʻe o ka uhi ʻana i nā noi hana o nā laser nanosecond maʻamau, hiki iā ia ke hoʻohana i kona ākea pulse haiki kūʻokoʻa, kiʻekiʻe repetition frequency, a me ka mana kiʻekiʻe kiʻekiʻe e hoʻokō i kekahi mau noi hoʻoponopono kikoʻī.e like me:

1. Ka hoʻohana ʻana i ka wehe ʻana i ka ʻili o ka pepa alumini oxide

ʻO nā huahana uila o kēia lā e lilo i mea lahilahi a māmā.Nui nā kelepona paʻalima, papa, a me nā lolouila e hoʻohana ana i ka alumini oxide lahilahi a māmā e like me ka pūpū huahana.I ka hoʻohana ʻana i ka laser Q-switched e hōʻailona i nā kūlana conductive ma kahi pā alumini lahilahi, hiki ke maʻalahi i ka hoʻololi ʻana o ka mea, e hopena i nā "hulls convex" ma ke kua, e pili pono ana i ka aesthetics o ka helehelena.ʻO ka hoʻohana ʻana i nā ʻāpana laula pulse liʻiliʻi o ka MOPA laser hiki ke hana i ka mea ʻaʻole maʻalahi ke hoʻololi ʻia, a ʻoi aku ka maʻalahi a me ka mālamalama o ka pale.ʻO kēia no ka hoʻohana ʻana o ka laser MOPA i kahi pānaʻi ākea pulse liʻiliʻi e hoʻolōʻihi i ka noho ʻana o ka laser ma luna o ka mea, a loaʻa iā ia ka ikehu kiʻekiʻe e hoʻoneʻe i ka papa anode, no laila no ka hana ʻana o ka wehe ʻana i ka anode ma luna o ka ʻili o ka alumini oxide. papa, MOPA Lasers kahi koho maikaʻi loa.

2.Anodized alumini blackening noi

Ke hoʻohana nei i nā lasers e hōʻailona i nā hōʻailona ʻeleʻele, nā hiʻohiʻona, nā kikokikona, etc.

Ma muli o ka MOPA pulsed fiber laser he ākea pulse ākea a me ka repetition frequency adjustment range, hiki i ka hoʻohana ʻana i ka laulā pulse liʻiliʻi a me nā ʻāpana alapine kiʻekiʻe ke hōʻailona i ka ʻili o ka mea me ka hopena ʻeleʻele.Hiki i nā hui like ʻole o nā ʻāpana ke hōʻailona i nā pae hina like ʻole.hopena.

No laila, ʻoi aku ka nui o ke koho ʻana no nā hopena kaʻina o ka ʻeleʻele like ʻole a me ka manaʻo lima, a ʻo ia ke kumu kukui i makemake ʻia no ka blackening anodized alumini ma ka mākeke.Hana ʻia ka mākaʻikaʻi ʻana ma nā ʻano ʻelua: mode dot a me ka mana kiko i hoʻoponopono ʻia.Ma ka hoʻoponopono ʻana i ka nui o nā kiko, hiki ke hoʻohālikelike ʻia nā hopena grayscale like ʻole, a hiki ke hōʻailona ʻia nā kiʻi maʻamau a me nā mea hana pilikino ma ka ʻili o nā mea alumini anodized.

3. Hōʻailona laser kala

I loko o ka noi kala kila kila, pono ka laser e hana me ka liʻiliʻi a me ka liʻiliʻi pulse ākea a me nā alapine kiʻekiʻe.Hoʻololi nui ʻia ka hoʻololi kala e ka pinepine a me ka mana.Hoʻopili nui ʻia ka ʻokoʻa o kēia mau kala e ka ikehu pulse hoʻokahi o ka laser ponoʻī a me ka nui o ka overlap o kona wahi ma ka mea.No ka mea hiki ke hoʻololi kūʻokoʻa ka laulā pulse a me ka pinepine o ka laser MOPA, ʻo ka hoʻoponopono ʻana i kekahi o lākou ʻaʻole ia e pili i nā ʻāpana ʻē aʻe.Hana pū lākou me kekahi i kekahi e hoʻokō i nā ʻano like ʻole, ʻaʻole hiki ke hoʻokō ʻia e ka laser Q-switched.Ma nā noi kūpono, ma ka hoʻoponopono ʻana i ka laulā pulse, frequency, power, speed, fill method, fill spacing and other parameters, permuting a hoʻohui i nā ʻāpana like ʻole, hiki iā ʻoe ke hōʻailona i ka nui o kona mau hopena kala, nā kala momona a me ka palupalu.Ma luna o ka papa ʻaina kila kila, nā mea lapaʻau a me nā mea hana lima, nā logo nani a i ʻole nā ​​hiʻohiʻona hiki ke kaha ʻia e pāʻani i kahi hopena hoʻonaninani nani.

Ma keʻano laulā, hiki ke hoʻololi kūʻokoʻa ka laulā pulse a me ka pinepine o ka MOPA fiber laser, a he nui ka laulā o ka hoʻoponopono, no laila maikaʻi ke kaʻina hana, haʻahaʻa ka hopena wela, a loaʻa iā ia nā pōmaikaʻi maikaʻi loa i ka hōʻailona alumini oxide, alumini anodized. ʻeleʻele, a me ke kala kila.E hoʻomaopopo i ka hopena i hiki ʻole ke hoʻokō i ka laser fiber Q-switched ʻO ka Q-switched fiber laser ka mea i hōʻike ʻia e ka mana kaha kaha, aia kekahi mau mea maikaʻi i ka hana ʻana i nā metala hohonu, akā ʻoi aku ka paʻakikī o ka hopena.Ma nā palapala hoailona maʻamau, ua hoʻohālikelike ʻia nā laser fiber pulsed MOPA me nā laser fiber Q-switched, a ua hōʻike ʻia kā lākou mau hiʻohiʻona nui ma ka papa ma lalo.Hiki i nā mea hoʻohana ke koho i ka laser kūpono e like me nā pono maoli o ka mākaʻikaʻi ʻana i nā mea a me nā hopena.

ʻO ka MOPA fiber laser pulse ākea a me ke alapine hiki ke hoʻololi kūʻokoʻa, a nui ka laulā o ka hoʻoponopono ʻana, no laila maikaʻi ke kaʻina hana, haʻahaʻa ka hopena wela, a loaʻa iā ia nā pōmaikaʻi maikaʻi loa i ka hoʻopaʻa ʻana i ka pepa alumini oxide, anodized alumini blackening, stainless steel kala, a me ka wili metala.ʻO ka hopena i hiki ʻole ke hoʻokō i ka laser fiber Q-switched.Hōʻike ʻia ka laser fiber Q-switched e ka mana kaha kaha, aia kekahi mau pono i ka hoʻoili ʻana i nā metala hohonu, akā ʻoi aku ka paʻakikī o ka hopena.

Ma keʻano laulā, hiki i nā laser fiber MOPA ke hoʻololi i nā laser fiber Q-switched i ka laser high-end marking a me nā noi wili.I ka wā e hiki mai ana, ʻo ka hoʻomohala ʻana o nā laser fiber MOPA e lawe i nā ākea pulse a me nā alapine kiʻekiʻe e like me ke kuhikuhi, a ma ka manawa like e hele ai i ka mana kiʻekiʻe a me ka ikehu kiʻekiʻe, e hoʻomau i ka hoʻokō i nā koi hou o ka hoʻoponopono maikaʻi ʻana i nā mea laser, a hoʻomau i ka hoʻomohala e like me ka laser derusting a me ka lidar.A me nā wahi noi hou ʻē aʻe.
