ʻO nā lasers paʻakikī Microcavity mai ka mea i kauoha ʻia i nā mokuʻāina ʻino

ʻO ka laser maʻamau he ʻekolu mau mea kumu: kahi puna puna, kahi mea waiwai e hoʻonui ai i ka radiation hoʻoulu ʻia, a me kahi ʻano lua e hoʻohua ai i kahi resonance optical. I ka nui o ka lua o kalaserkokoke i ka micron a i ʻole submicron pae, ua lilo ia i hoʻokahi o nā wahi hotspots noiʻi i kēia manawa ma ke kaiāulu hoʻonaʻauao: microcavity lasers, hiki ke hoʻokō i ka mālamalama nui a me ka pilina mea ma kahi leo liʻiliʻi. ʻO ka hoʻohui ʻana i nā microcavities me nā ʻōnaehana paʻakikī, e like me ka hoʻokomo ʻana i nā palena o ka lua ʻole a i ʻole ka hoʻokomo ʻana i nā media hana paʻakikī a i ʻole nā ​​​​mea hana ʻino i loko o nā microcavities, e hoʻonui i ke kiʻekiʻe o ke kūʻokoʻa o ka hoʻopuka laser. ʻO nā hiʻohiʻona non-cloning kino o nā cavities disordered e lawe mai i nā ʻano mana multidimensional o nā ʻāpana laser, a hiki ke hoʻonui i kona hiki ke noi.

Nā ʻōnaehana like ʻole o ka randomnā laser microcavity
I loko o kēia pepa, ua hoʻokaʻawale ʻia nā laser microcavity random mai nā ana lua ʻokoʻa no ka manawa mua. ʻAʻole hōʻike wale kēia ʻokoʻa i nā hiʻohiʻona kūʻokoʻa o ka laser microcavity random i nā ʻāpana like ʻole, akā wehewehe pū kekahi i nā pono o ka ʻokoʻa nui o ka microcavity random i nā ʻano hoʻoponopono a me nā kahua noi. ʻO ka microcavity solid-state ʻekolu-dimensional he ʻano liʻiliʻi ka leo, no laila e loaʻa ai ka ʻoi aku ka ikaika o ka māmā a me ka pilina mea. Ma muli o kona ʻano paʻa ʻekolu-dimensional, hiki ke hoʻokaʻawale ʻia ke kahua māmā i ʻekolu mau ʻāpana, pinepine me kahi kumu kiʻekiʻe (Q-factor). Kūpono kēia mau hiʻohiʻona no ka ʻike kiʻekiʻe kiʻekiʻe, ka mālama ʻana i nā photon, ka hoʻoili ʻike quantum a me nā ʻenehana ʻenehana holomua ʻē aʻe. ʻO ka ʻōnaehana kiʻiʻoniʻoni lahilahi wehe ʻelua he kahua kūpono no ke kūkulu ʻana i nā hale hoʻolālā ʻino. Ma ke ʻano he mokulele dielectric maʻi ʻelua-dimensional me ka loaʻa a me ka hoʻopuehu ʻana, hiki i ka ʻōnaehana kiʻiʻoniʻoni lahilahi ke komo ikaika i ka hana o ka laser random. E maʻalahi ka hoʻopili ʻana a me ka hōʻiliʻili ʻana i ka hopena hawewe planar. Me ka hoemi hou ana o ke ana o ka lua, hiki i ka hoohui ana o ka pane a me ka loaa ana o ka media i ke alakai nalu hookahi ke hoopau i ka hoopuehu ana i ka malamalama radial me ka hoonui ana i ka resonance a me ka hoohui. ʻO kēia ala hoʻohui e hoʻomaikaʻi i ka maikaʻi o ka hana laser a me ka hoʻohui ʻana.

Nā hiʻohiʻona hoʻoponopono o nā laser microcavity random
ʻO nā hōʻailona he nui o nā laser maʻamau, e like me ka coherence, threshold, output direction a me nā hiʻohiʻona polarization, ʻo ia ke kumu nui e ana i ka hana hoʻopuka o nā lasers. Hoʻohālikelike ʻia me nā lasers maʻamau me nā lua symmetric paʻa, hāʻawi ka laser microcavity random i ʻoi aku ka maʻalahi o ka hoʻoponopono ʻana i nā ʻāpana, i ʻike ʻia i nā ʻano he nui me ka domain time, spectral domain a me spatial domain, e hōʻike ana i ka controllability multi-dimensional o ka laser microcavity random.

Nā hiʻohiʻona noi o nā laser microcavity random
Haʻahaʻa spatial coherence, mode randomness a me ka sensitivity i ke kaiapuni e hāʻawi i nā kumu maikaʻi no ka hoʻohana ʻana i nā lasers stochastic microcavity. Me ka hopena o ka mana mode a me ka mana kuhikuhi o ka laser random, ua hoʻohana nui ʻia kēia kumu kukui kūʻokoʻa i ke kiʻi kiʻi, ka maʻi maʻi maʻi, ka ʻike, ke kamaʻilio ʻike a me nā kahua ʻē aʻe.
E like me ka laser micro-cavity disordered ma micro and nano scale, ʻo ka microcavity laser random ka mea maʻalahi loa i nā loli kaiapuni, a hiki i kāna mau hiʻohiʻona parametric ke pane i nā ʻano hōʻailona koʻikoʻi e nānā ana i ka kaiapuni o waho, e like me ka mahana, ka haʻahaʻa, ka pH, ka ʻike wai, refractive index, etc., ka hana ʻana i kahi paepae ʻoi aku ka maikaʻi no ka hoʻokō ʻana i nā noi ʻike kiʻekiʻe. Ma ke kahua o ke kiʻi, ka mea kūponokumu kukuiPono e loaʻa i ka mānoanoa spectral kiʻekiʻe, ka puka kuhikuhi ikaika a me ka hoʻopili spatial haʻahaʻa e pale i nā hopena speckle interference. Ua hōʻike ka poʻe noiʻi i ka maikaʻi o nā laser random no ke kiʻi kikoʻī ʻole i loko o ka perovskite, biofilm, nā mea hoʻopuehu aniani wai a me nā mea lawe pūnaewele. Ma ka hōʻoia olakino, hiki i ka laser microcavity random ke lawe i ka ʻike i hoʻopuehu ʻia mai ka pūʻali olaola, a ua hoʻohana maikaʻi ʻia e ʻike i nā ʻiʻo olaola like ʻole, e hāʻawi i ka maʻalahi no ka maʻi lapaʻau non-invasive.

I ka wā e hiki mai ana, ʻoi aku ka piha o ka loiloi ʻōnaehana o nā ʻōnaehana microcavity pilikia a me nā mīkini hana laser paʻakikī. Me ka holomua mau o ka ʻepekema waiwai a me ka nanotechnology, ua manaʻo ʻia e hana ʻia nā hale microcavity disordered maikaʻi a maikaʻi hoʻi, i hiki ke hoʻoikaika i ka noiʻi kumu a me nā noi kūpono.
