ʻO ka hoʻomohala ʻana a me ka hoʻohana ʻana o Laser Crystal

ʻO nā kristal laser a me kā lākou mau ʻāpana ke kumu kumu nui no ka ʻoihana optoelectronics.ʻO ia hoʻi ka mea koʻikoʻi o nā lasers solid-state e hana i ka kukui laser.I ka ʻike ʻana i nā mea maikaʻi o ka like ʻana o ka optical maikaʻi, nā waiwai mechanical maikaʻi, ke kūpaʻa kino a me ke kemika maikaʻi, a me ka conductivity thermal maikaʻi, ʻo nā kristal laser nā mea kaulana no nā lasers solid-state.No laila, hoʻohana nui ʻia i nā ʻoihana ʻoihana, lāʻau lapaʻau, noiʻi ʻepekema, kamaʻilio a me nā ʻoihana koa.E like me ka laser ranging, laser target indication, laser detection, laser marking, laser cutting processing (me ka ʻoki ʻana, drilling, welding and engraving, etc.), laser medical treatment, a me ka nani laser, etc.

ʻO ka laser e pili ana i ka hoʻohana ʻana i ka hapa nui o nā mea hana i loko o ka hau hauʻoli, a me ka hoʻohana ʻana i ka induction kukui o waho e hana ai i nā ʻāpana āpau o ka hau hauʻoli e hoʻopau i ka radiation hoʻoulu ʻia i ka manawa like, e hana ana i kahi kukui ikaika.ʻO nā lasers he alakaʻi maikaʻi loa, monochromaticity a me ka coherence, a ma ka nānā ʻana i kēia mau hiʻohiʻona, hoʻohana nui ʻia ia ma nā ʻano āpau o ke kaiāulu.

ʻElua mau ʻāpana o ka kristal laser, ʻo kekahi ka ion i hoʻāla ʻia ma ke ʻano he "luminescence center", a ʻo kekahi ʻo ka kristal host e like me ka "carrier" o ka ion i hoʻāla ʻia.ʻO ka mea nui ma waena o nā kristal hoʻokipa ʻo nā kristal oxide.Loaʻa i kēia mau kristal nā pono kūʻokoʻa e like me ke kiʻekiʻe heheʻe, ka paʻakikī kiʻekiʻe a me ka conductivity thermal maikaʻi.Ma waena o lākou, hoʻohana nui ʻia ka ruby ​​​​a me YAG, no ka mea, hiki i kā lākou lattice defects ke komo i ka mālamalama ʻike ʻia i kekahi ʻano spectral e hōʻike i kahi kala, a laila e ʻike ai i ka oscillation laser tunable.

Ma waho aʻe o nā laser kristal kahiko, ke ulu nei nā kristal laser i ʻelua ʻaoʻao: ultra-nui a me ultra-liʻiliʻi.Hoʻohana nui ʻia nā laser kristal ultra-nui i ka fusion nuklea laser, ka hoʻokaʻawale ʻana i ka isotope laser, ka ʻoki ʻana a me nā ʻoihana ʻē aʻe.ʻO nā laser kristal liʻiliʻi liʻiliʻi e pili ana i nā laser semiconductor.Loaʻa iā ia nā pōmaikaʻi o ka maikaʻi o ka pumping kiʻekiʻe, ka ukana wela liʻiliʻi o ke aniani, ka hopena laser paʻa, ke ola lōʻihi, a me ka liʻiliʻi o ka laser, no laila he manaʻo hoʻomohala nui i nā noi kikoʻī.
