Ke hoʻolauna nei i ka "ʻUhane" o nā lasers paʻa-mokuʻāina

Ka Waiwai Nuilaser paʻa-kūlananā mea hana

ʻO ke kikowaena o kēlā me kēia laser ka mea hana laser, a ʻo ka mea hana o kahi mokuʻāina paʻalaserhe paʻa maoli. ʻO ka hapa nui o nā mea hana laser paʻa-mokuʻu i haku ʻia me nā matrices kristal a me nā ʻātoma i hoʻohui ʻia a i ʻole nā ​​​​iona me ka hana laser, ʻoiai he mea kakaikahi nā matrices amorphous (aniani). Manaʻo ʻia ka hoʻomohala hou loa i ka ʻenehana hoʻomākaukau keramika e hoʻonui nui i ka laulā noi o nā mea laser haʻahaʻa a me ke kiʻekiʻe, hiki ke hana ʻia i kahi nui ʻoi aku ka nui ma mua o nā mea kristal.

Nā mea laser paʻa-mokuʻāina i hoʻohana pinepine ʻia

Ruby: ʻO kona ʻano kemika he chromium-doped aluminum oxide (Cr:Al₂O₃). He ʻano kemika like ko nā rubies artificial me nā rubies gem-quality, akā ʻoi aku ka maʻemaʻe a me ke ʻano. He ʻulaʻula ko lākou ʻano a he 694.3 nanometers ka lōʻihi o ka nalu laser.

2. Neodymium-doped yttrium aluminum garnet (Nd:YAG): ʻO ke aniani hana, me ka nalu laser o 1064 nanometers, pili ia i ka mālamalama kokoke-infrared a ʻike ʻole ʻia a palekana ʻole no nā maka. ʻO Nd:YAG ka mea laser paʻa i hoʻohana nui ʻia i kēia manawa, ʻoi aku ka nui ma mua o ka ruby. ʻO ke kumu nui, ʻoi aku ka haʻahaʻa o kona paepae laser, a hiki iā ia ke hoʻokō i ka ikehu hoʻopuka kiʻekiʻe ma lalo o ka ikehu hoʻokomo like.

3. Neodymium-doped yttrium vanadate (Nd:YVO₄) I kapa pinepine ʻia ʻo "vanadate", ua lilo ia i mea makemake ʻia no ka mana haʻahaʻa a waena (a hiki i kekahi mau watts) diode-pumped solid-state lasers ma muli o kona ʻāpana hoʻokuʻu hoʻoulu nui ʻia, ka paepae laser haʻahaʻa a me nā ʻano hoʻopuka polarized. ʻO nā nalu hana he 1064 nanometers a me 1340 nanometers, a ma hope o ka pālua ʻana o ke alapine, hiki iā ia ke hoʻopuka i nā lasers me nā nalu o 532 nanometers a me 670 nanometers.

4. Ke Aniani Neodymium-doped (Nd:Glass): Ke hoʻohana nei i ke aniani amorphous ma ke ʻano he matrix, ua like kona mau waiwai laser me ko Nd:YAG. ʻO kona hemahema nui, ʻo ia ka haʻahaʻa o kona conductivity thermal, 1/10 wale nō o ke kristal, e paʻakikī ai ke hoʻomaʻalili i nā noi mana kiʻekiʻe. Eia nō naʻe, aia kona pono i ka ʻoiaʻiʻo hiki ke hana ʻia i loko o nā media laser me ke anawaena ma mua o hoʻokahi kapuaʻi, e kaohi pono ana i ka nui o ka ikehu, e pale ana i ka hōʻino ʻana i nā ʻāpana optical ma ka pae kilojoule.laser pulsed, a he haʻahaʻa ke kumukūʻai.

ʻO nā mea laser paʻa koʻikoʻi ʻē aʻe, nā mea i hoʻopili ʻia me ka erbium: me ka erbium-doped yttrium aluminum garnet (Er:YAG, ka nalu hoʻopuka 2940 nanometers) a me ke aniani erbium-doped (Er:Glass, ka nalu hoʻopuka 1540 nanometers). Nā mea i hoʻopili ʻia me ka holmium: me ka holmium doped yttrium aluminum garnet (Ho:YAG), holmium doped lithium yttrium fluoride (Ho:YLF), a me ka holmium doped Glass (Ho: aniani, ka nalu hoʻopuka 2000 a 2100 nanometers). Nā mea i hoʻopili ʻia me ka Thulium: me ka thulium-doped yttrium aluminum garnet (Tm:YAG), thulium-doped lutetium aluminum garnet (Tm:LuAG), a me ka thulium-holmium co-doped lithium yttrium fluoride (Tm,Ho:YLF, ka nalu hoʻopuka 2000 a 2030 nanometers). Nā mea i hoʻopili ʻia me Ytterbium: e like me ka ytterbium-doped potassium gadolinium tungstate (Yb:KGW, ka nalu hoʻopuka 1025 a 1045 nanometers). Alexandrite (ka nalu hoʻopuka 655 a 815 nanometers). Sapphire i hoʻopili ʻia me Titanium (Ti:Sapphire, ka nalu hoʻopuka 840 a 1100 nanometers)
