Nūhou - Ke Koʻikoʻi o nā Lasers i nā noi pale kaua

E kākau inoa i kā mākou pāpili kaiapili no ka pou wikiwiki

Ua lilo nā lasers i mea koʻikoʻi i nā noi pale kaua, e hāʻawi ana i nā hiki i hiki ʻole i nā mea kaua kuʻuna ke hoʻokūkū. Ke noiʻi nei kēia blog i ke koʻikoʻi o nā lasers i ka pale kaua, e hōʻike ana i ko lākou versatility, pololei, a me nā holomua ʻenehana i hoʻolilo iā lākou i kihi o ka hoʻolālā koa hou.

Hoʻolauna

Ua hoʻololi ka hoʻomaka ʻana o ka ʻenehana laser i nā ʻāpana he nui, me ke kelepona, ka lāʻau lapaʻau, a ʻo ka mea nui, ka pale kaua. ʻO nā lasers, me ko lākou mau waiwai kūikawā o ke kūlike, ka monochromaticity, a me ka ikaika kiʻekiʻe, ua wehe i nā ʻano hou i nā hiki koa, e hāʻawi ana i ka pololei, ka malū, a me ka versatility i waiwai nui ʻia i nā hoʻolālā kaua a me nā pale kaua hou.

Ka Pololei a me ka Pololei

Ua kaulana nā lasers no ko lākou pololei a me ka pololei. ʻO ko lākou hiki ke kālele i nā pahuhopu liʻiliʻi ma nā mamao loa e lilo ai lākou i mea nui no nā noi e like me ke kuhikuhi ʻana i ka pahuhopu a me ke alakaʻi missile. Hōʻoia nā ʻōnaehana kuhikuhi laser kiʻekiʻe i ka hāʻawi pololei ʻana o nā mea kaua, e hōʻemi nui ana i ka pōʻino collateral a hoʻonui i nā helu holomua misionari (Ahmed, Mohsin, & Ali, 2020).

Ka Versatility ma nā Paepae āpau

ʻO ka hiki ke hoʻololi i nā lasers ma nā kahua like ʻole - mai nā mea paʻa lima a hiki i nā ʻōnaehana nui i kau ʻia ma ke kaʻa - e hōʻike ana i ko lākou versatility. Ua hoʻohui pono ʻia nā lasers i loko o nā kahua honua, moana, a me ka lewa, e lawelawe ana i nā kuleana he nui e like me ka nānā ʻana, ka loaʻa ʻana o ka pahuhopu, a me nā mea kaua ikehu pololei no nā kumu hoʻouka kaua a me ka pale ʻana. ʻO ko lākou nui liʻiliʻi a me ka hiki ke hoʻopilikino ʻia no nā noi kikoʻī e hoʻolilo i nā lasers i koho maʻalahi no nā hana pale (Bernatskyi & Sokolovskyi, 2022).

Hoʻonui ʻia ke kamaʻilio a me ka nānā ʻana

Hāʻawi nā ʻōnaehana kamaʻilio laser i kahi ala palekana a maikaʻi hoʻi no ka hoʻouna ʻana i ka ʻike, he mea nui ia no nā hana koa. ʻO ka haʻahaʻa o ka hiki ke hoʻopaʻa a me ka ʻike ʻana i nā kamaʻilio laser e hōʻoiaʻiʻo ana i ka hoʻololi ʻikepili palekana a manawa maoli ma waena o nā ʻāpana, e hoʻonui ana i ka ʻike kūlana a me ka hoʻonohonoho ʻana. Eia kekahi, he kuleana koʻikoʻi nā lasers i ka nānā ʻana a me ka ʻimi ʻana, e hāʻawi ana i nā kiʻi kiʻekiʻe no ka hōʻiliʻili ʻike me ka ʻike ʻole ʻia (Liu et al., 2020).

Nā Mea Kaua Ikehu i Kuhikuhi ʻia

ʻO ka hoʻohana nui ʻana paha o nā lasers i ka pale kaua ʻana ma ke ʻano he mau mea kaua ikehu i kuhikuhi ʻia (DEWs). Hiki i nā lasers ke hāʻawi i ka ikehu i hoʻopaʻa ʻia i kahi pahuhopu e hōʻino a luku paha iā ia, e hāʻawi ana i kahi hiki ke hahau pololei me ka liʻiliʻi o ka pōʻino collateral. ʻO ka hoʻomohala ʻana i nā ʻōnaehana laser ikehu kiʻekiʻe no ka pale kaua missile, ka luku drone, a me ka hiki ʻole o ke kaʻa ke hōʻike i ka hiki o nā lasers ke hoʻololi i ke ʻano o nā hoʻouka kaua koa. Hāʻawi kēia mau ʻōnaehana i nā pono koʻikoʻi ma luna o nā mea kaua kuʻuna, me ka wikiwiki o ka lawe ʻana i ka mālamalama, ke kumukūʻai haʻahaʻa no kēlā me kēia pana, a me ka hiki ke hoʻopili i nā pahuhopu he nui me ka pololei kiʻekiʻe (Zediker, 2022).

I nā noi pale kaua, hoʻohana ʻia nā ʻano laser like ʻole, e lawelawe ana kēlā me kēia i nā kumu hana like ʻole e pili ana i kā lākou mau waiwai kūikawā a me nā hiki. Eia kekahi o nā ʻano laser i hoʻohana nui ʻia i nā noi pale kaua:

Nā ʻano Laser i hoʻohana ʻia ma ke kahua pale

Nā Lasers Paʻa-Mokuʻāina (SSLs)Hoʻohana kēia mau lasers i kahi medium loaʻa paʻa, e like me ke aniani a i ʻole nā mea crystalline i hoʻohui ʻia me nā mea honua laha ʻole. Hoʻohana nui ʻia nā SSL no nā mea kaua laser ikehu kiʻekiʻe ma muli o ko lākou mana hoʻopuka kiʻekiʻe, ka pono, a me ke ʻano o ka kukuna. Ke hoʻāʻo ʻia nei a hoʻolaha ʻia no ka pale kaua missile, ka luku drone, a me nā noi mea kaua ikehu pololei ʻē aʻe (Hecht, 2019).

Nā Lasers FiberHoʻohana nā lasers fiber i kahi fiber optical doped ma ke ʻano he mea hoʻonui, e hāʻawi ana i nā pono ma ke ʻano o ka maʻalahi, ka maikaʻi o ke kukuna, a me ka pono. He mea hoihoi loa lākou no ka pale ʻana ma muli o ko lākou liʻiliʻi, ka hilinaʻi, a me ka maʻalahi o ka hoʻokele wela. Hoʻohana ʻia nā lasers fiber i nā noi koa like ʻole, me nā mea kaua ikehu i kuhikuhi ʻia me ka mana kiʻekiʻe, ka hoʻolālā pahuhopu, a me nā ʻōnaehana countermeasure (Lazov, Teirumnieks, & Ghalot, 2021).

Nā Lasers KemikaHoʻopuka nā lasers kemika i ka mālamalama laser ma o nā hopena kemika. ʻO kekahi o nā lasers kemika i ʻike nui ʻia i ka pale ʻana ʻo ia ka Chemical Oxygen Iodine Laser (COIL), i hoʻohana ʻia i nā ʻōnaehana laser ea no ka pale kaua missile. Hiki i kēia mau lasers ke hoʻokō i nā pae mana kiʻekiʻe loa a he pono ia ma nā mamao lōʻihi (Ahmed, Mohsin, & Ali, 2020).

Nā Lasers Semiconductor:ʻIke ʻia hoʻi he mau diode laser, he mau lasers liʻiliʻi a kūpono hoʻi kēia i hoʻohana ʻia i nā ʻano noi like ʻole mai nā rangefinders a me nā mea hoʻolālā pahuhopu i nā countermeasures infrared a me nā kumu pump no nā ʻōnaehana laser ʻē aʻe. ʻO ko lākou liʻiliʻi a me ka pono e kūpono ai lākou no nā ʻōnaehana pale lawe lima a me nā ʻōnaehana pale i kau ʻia ma ke kaʻa (Neukum et al., 2022).

Nā Lasers Hoʻopuka ʻIli Kū i luna (VCSELs)Hoʻopuka nā VCSEL i ke kukui laser e kū pono ana i ka ʻili o kahi wafer i hana ʻia a hoʻohana ʻia i nā noi e koi ana i ka hoʻohana ʻana i ka mana haʻahaʻa a me nā mea ʻano liʻiliʻi, e like me nā ʻōnaehana kamaʻilio a me nā mea ʻike no nā noi pale (Arafin & Jung, 2019).

Nā Lasers Polū:Ke noiʻi ʻia nei ka ʻenehana laser polū no nā noi pale ma muli o kona mau ʻano omo i hoʻonui ʻia, hiki ke hōʻemi i ka ikehu laser e pono ai ma ka pahuhopu. ʻO kēia ka mea e hiki ai i nā laser polū ke lilo i mau moho no ka pale drone a me ka pale missile hypersonic, e hāʻawi ana i ka hiki ke hoʻohana i nā ʻōnaehana liʻiliʻi a māmā me nā hopena kūpono (Zediker, 2022).
