ʻO nā hiʻohiʻona nui o ka medium gain laser

He aha nā hiʻohiʻona nui o ka media gain laser?

ʻO ka laser gain medium, ka mea i ʻike ʻia he mea hana laser, e pili ana i ka ʻōnaehana waiwai i hoʻohana ʻia no ka hoʻohuli ʻana i ka heluna kanaka a hoʻoulu i ka radiation hoʻoulu ʻia e hoʻokō i ka hoʻonui māmā. ʻO ia ka mea nui o ka laser, e lawe ana i ka nui o nā ʻātoma a i ʻole nā ​​molekole, ʻo kēia mau ʻātoma a i ʻole nā ​​mole ma lalo o ka hauʻoli o ka ikehu o waho, hiki ke hoʻololi i ke kūlana hauʻoli, a ma o ka hoʻoulu ʻana i hoʻokuʻu ʻia nā photons, pēlā e hana ai i kahikukui laser. Hiki ke paʻa, wai, kinoea a i ʻole semiconductor ka laser loaʻa medium.
I loko o nā lasers solid-state, ʻo ka mea hoʻohana maʻamau i loaʻa i ka media he mau kristal i hoʻopaʻa ʻia me nā ion honua laha a i ʻole nā ​​​​iona metala hoʻololi, e like me Nd:YAG crystals, Nd:YVO4 crystals, etc. Hoʻohana nā laser gas i ke kinoea ma ke ʻano he kumu waiwai, e like me ke kinoea carbon dioxide i nā laser carbon dioxide, a me ka helium a me ke kinoea neon i nā lasers helium-neon.Nā laser semiconductorE hoʻohana i nā mea semiconductor ma ke ʻano he mea waiwai, e like me gallium arsenide (GaAs).
ʻO nā hiʻohiʻona koʻikoʻi o ka medium gain laser ka:
Ka hoʻolālā pae ikehu: Pono nā ʻātoma a i ʻole nā ​​molekole i loko o ka ʻenehana loaʻa i kahi ʻano pae ikehu kūpono i mea e hoʻokō ai i ka huli ʻana o ka heluna kanaka ma lalo o ka hauʻoli o ka ikehu o waho. ʻO ke ʻano maʻamau, pono ka ʻokoʻa o ka ikehu ma waena o nā pae ikehu kiʻekiʻe a haʻahaʻa e like me ka ikehu photon o kekahi lōʻihi hawewe.

Nā waiwai hoʻololi: Pono nā ʻātoma a i ʻole nā ​​molekole i nā mokuʻāina hauʻoli e loaʻa nā waiwai hoʻololi paʻa i mea e hoʻokuʻu ai i nā kiʻi paʻi like ʻole i ka wā hoʻohiwahiwa hauʻoli. Pono kēia i ka medium loaʻa e loaʻa ka maikaʻi quantum kiʻekiʻe a me ka poho haʻahaʻa.
ʻO ke kūpaʻa wela a me ka ikaika mechanical: I nā noi kūpono, pono ka loaʻa ʻana o ka medium e kū i ke kukui uila mana kiʻekiʻe a me ka hoʻopuka laser, no laila pono e loaʻa ka paʻa wela maikaʻi a me ka ikaika mechanical.
ʻO ka maikaʻi Optical: ʻO ka maikaʻi o ka optical medium ka mea koʻikoʻi i ka hana o ka laser. Pono e loaʻa i ka transmittance māmā kiʻekiʻe a me ka nalowale haʻahaʻa haʻahaʻa e hōʻoia i ka maikaʻi a me ke kūpaʻa o ka kukuna laser. ʻO ke koho ʻana o ka laser gain medium ma muli o nā koi noi o kalaser, ka nalu hana, ka mana puka a me nā mea ʻē aʻe. Ma ka hoʻonui ʻana i ka waiwai a me ke ʻano o ka medium gain, hiki ke hoʻomaikaʻi hou ʻia ka hana a me ka pono o ka laser.
