Ka Hopena o ka Nalu ma nā Kaʻina Hana ʻenehana Laser

Hoʻopilikia nui ka nalu o ka laser i ke kaʻina hana, ʻoi aku hoʻi no nā mea e like me ke kila kūkulu. Ua kālailai ʻia nā lasers e hoʻopuka ana i nā wahi ultraviolet, ʻike ʻia, kokoke a mamao o ka infrared no ko lākou mana koʻikoʻi no ka hoʻoheheʻe ʻana a me ka mahu (Lazov, Angelov, & Teirumnieks, 2019).

Nā noi like ʻole e pili ana i nā nalu

ʻAʻole koho wale ʻia ke koho ʻana o ka nalu laser akā hilinaʻi nui ia i nā waiwai o ka mea a me ka hopena i makemake ʻia. No ka laʻana, ʻoi aku ka maikaʻi o nā lasers UV (me nā nalu pōkole) no ke kahakaha pololei a me ka micromachining, no ka mea hiki iā lākou ke hana i nā kikoʻī maikaʻi aʻe. ʻO kēia ka mea kūpono iā lākou no nā ʻoihana semiconductor a me microelectronics. I ka hoʻohālikelike ʻana, ʻoi aku ka maikaʻi o nā lasers infrared no ka hana ʻana i nā mea mānoanoa ma muli o ko lākou hiki ke komo hohonu, e kūpono ai lākou no nā noi ʻoihana kaumaha. (Majumdar & Manna, 2013). Pēlā nō, ʻo nā lasers ʻōmaʻomaʻo, e hana pinepine ana ma kahi nalu o 532 nm, loaʻa i ko lākou niche i nā noi e koi ana i ka pololei kiʻekiʻe me ka hopena wela liʻiliʻi. He kūpono loa lākou i ka microelectronics no nā hana e like me ke ʻano circuit, i nā noi lapaʻau no nā kaʻina hana e like me ka photocoagulation, a ma ka ʻāpana ikehu hou no ka hana ʻana o nā cell solar. ʻO ka nalu kū hoʻokahi o nā lasers ʻōmaʻomaʻo e kūpono iā lākou no ka hōʻailona a me ke kahakaha ʻana i nā mea like ʻole, me nā plastics a me nā metala, kahi e makemake ʻia ai ke ʻano kiʻekiʻe a me ka pōʻino liʻiliʻi o ka ʻili. Hōʻike kēia hoʻololi o nā lasers ʻōmaʻomaʻo i ke koʻikoʻi o ke koho ʻana i ka nalu i ka ʻenehana laser, e hōʻoiaʻiʻo ana i nā hopena maikaʻi loa no nā mea kikoʻī a me nā noi.

ʻO kaKukuna ʻōmaʻomaʻo 525nmhe ʻano kikoʻī o ka ʻenehana laser i hōʻike ʻia e kāna hoʻokuʻu kukui ʻōmaʻomaʻo ʻokoʻa ma ka nalu o 525 nanometers. Loaʻa i nā lasers ʻōmaʻomaʻo ma kēia nalu ka hoʻohana ʻana i ka photocoagulation retinal, kahi e pono ai ko lākou mana kiʻekiʻe a me ka pololei. He mea pono nō hoʻi lākou i ka hana ʻana i nā mea, ʻoi aku hoʻi i nā kahua e pono ai ka hana ʻana i ka hopena wela pololei a me ka liʻiliʻi..ʻO ka hoʻomohala ʻana o nā diode laser ʻōmaʻomaʻo ma ka substrate c-plane GaN i nā nalu lōʻihi ma 524-532 nm e hōʻailona ana i kahi holomua koʻikoʻi i ka ʻenehana laser. He mea koʻikoʻi kēia hoʻomohala ʻana no nā noi e koi ana i nā ʻano nalu kikoʻī.

Nā Kumu Nalu Hoʻomau a me nā Kumu Laser i Hoʻohālike ʻia

ʻO nā kumu laser hoʻomau (CW) a me nā kumu laser quasi-CW i hoʻohālikelike ʻia ma nā nalu like ʻole e like me ka infrared kokoke (NIR) ma 1064 nm, ʻōmaʻomaʻo ma 532 nm, a me ka ultraviolet (UV) ma 355 nm e noʻonoʻo ʻia no ka hoʻopili ʻana o ka laser i nā cell solar emitter koho. Loaʻa nā hopena o nā nalu like ʻole no ka hana ʻana i ka hoʻololi a me ka pono (Patel et al., 2011).

Nā Lasers Excimer no nā Mea Wide Band Gap

ʻO nā lasers Excimer, e hana ana ma kahi nalu UV, he kūpono ia no ka hana ʻana i nā mea ākea-bandgap e like me ke aniani a me ka polymer carbon-reinforced fiber (CFRP), e hāʻawi ana i ka pololei kiʻekiʻe a me ka hopena wela liʻiliʻi (Kobayashi et al., 2017).

Nā Lasers Nd:YAG no nā noi ʻoihana

ʻO nā lasers Nd:YAG, me ko lākou hiki ke hoʻololi i ke ʻano o ka hoʻonohonoho ʻana i ka nalu, hoʻohana ʻia i nā ʻano hana like ʻole. ʻO ko lākou hiki ke hana ma 1064 nm a me 532 nm e ʻae i ka maʻalahi i ka hana ʻana i nā mea like ʻole. No ka laʻana, ʻo ka nalu 1064 nm he kūpono no ke kahakaha hohonu ʻana ma nā metala, ʻoiai ʻo ka nalu 532 nm e hāʻawi i ke kahakaha ʻana i ka ʻili kiʻekiʻe ma nā plastics a me nā metala i uhi ʻia. (Moon et al., 1999).

Kuʻihao Laser Fiber Mana Kiʻekiʻe

Hoʻohana ʻia nā lasers me nā nalu kokoke i 1000 nm, nona ke ʻano kukuna maikaʻi a me ka mana kiʻekiʻe, i ka hoʻopili ʻana i ka laser keyhole no nā metala. Hoʻoheheʻe pono kēia mau lasers i nā mea, e hana ana i nā hoʻopili kiʻekiʻe (Salminen, Piili, & Purtonen, 2010).

Hoʻohui ʻana o ka Hana ʻana o ka Laser me nā ʻenehana ʻē aʻe

ʻO ka hoʻohui ʻana o ka hana laser me nā ʻenehana hana ʻē aʻe, e like me ke kāpili ʻana a me ka wili ʻana, ua alakaʻi i nā ʻōnaehana hana ʻoi aku ka maikaʻi a me ka maʻalahi. He mea pono loa kēia hoʻohui ʻana i nā ʻoihana e like me ka hana ʻana i nā mea hana a me nā make a me ka hoʻoponopono ʻenekini (Nowotny et al., 2010).
