ʻAʻole mākou ʻike i ka ʻenehana laser
ʻAʻole mākou ʻike i ka ʻenehana laser, ʻo 1960 wale nō ka hana laser kūleʻa mua loa.I ka hihia o ka laser mea theoretical hoomakaukau a me ka hana hana hana urgently pono kāʻei kua puka mai, ua puka mai, e kiʻi i ka hoʻokēʻai hoʻomohala 'ana o ka mea maʻamau,ʻaʻole wale ka ulu ana o ka laser no laila, i ka 'epekema kahiko o ka optics a me ka 'ike loea hou i loaʻa i ke ola hou. akā alakaʻi pū i ka puka ʻana o kahi puka ʻoihana hou.ʻO ka mīkini ʻoki ʻoki ʻana i ka laser hiki i ka poʻe ke hoʻohana pono i nā ʻano hana holomua a me nā ala, e loaʻa ai nā pōmaikaʻi a me nā hopena i ʻike ʻole ʻia, i mea e hoʻoikaika ai i ka hoʻomohala ʻana i nā mana huahana.
Eia nō naʻe, e like me ka ʻoki ʻana i ka laser laser, ka welding laser, ka mīkini ʻoki laser i hoʻohana nui ʻia i ke ola ma waena o ka hana ʻana, akā ʻo ke aniani laser hoʻi, ʻo ka laser terahertz ka ʻike like ʻole, ʻaʻole mākou i hoʻopili i ka mea kākau o kēia ʻatikala alakaʻi i nā mea a pau e nānā i nā mea a mākou ʻaʻole. kamaʻāina me ka ʻenehana laser.
Hiki ke hoʻolako ʻia ka mīkini ʻokiʻoki ʻoki ʻoki ʻana i ka ikehu aniani e ka lua optical waho i loko o ka spatial a me ke kino coherence i nā mea crystalline i kūlike loa a me ka kukui laser monochromatic.ʻO ka mea hana he laser kristal.ʻO ke aniani laser e nā kikowaena luminescence a me nā kristal matrix i haku ʻia i ʻelua ʻāpana.ʻO ka hapa nui o ke kikowaena hoʻomāmā ma o ka hoʻāla ʻana i ka hoʻolālā kristal ion, ua hoʻololi ʻia nā ion ikaika i ka cation matrix crystals doped laser crystals.Ke ho'ā ʻoe i ka ion e lilo i ʻāpana o nā ʻāpana aniani hoʻokipa, ʻo ia kahi aniani laser hoʻōla ponoʻī.
Hoʻohana nui ʻia ka mīkini ʻoki ʻoki ʻoki laser no nā ion metala hoʻololi ionic ikaika a me nā iona honua laha ʻole.Optical uila transition metala ion i loko o ka waho papa 3 d electrons i crystals e like me optical uila vulnerable i ka hopena pololei o ke aniani kahua a puni, no laila, okoa 'ano o ka hale aniani, kona spectral hiʻona okoa loa.ʻO Trivalent rare earth ions 4 f electrons he shielding effect 5 s a me 5 p waho electrons, no laila, i ka crystal field weakening o kona kuleana, akā, i ka hana o ka crystal field perturbation kumu ua papaia 4 f electron transitions hiki ke hana haiki absorption. a me ka laina fluorescence.No laila, ʻekolu mau ʻiona honua laha ʻole i loko o ke ʻano o nā ʻiona metala hoʻololi like ʻole e like me ka loli nui.
