He aha ka Optical Pumping ma Laser?

Nā ʻano like ʻole o nā Lasers Optically Pumped

1. Nā Lasers Paʻa-Mokuʻāina me nā Insulators Doped

· Nānā Laulā:Hoʻohana kēia mau lasers i kahi kikowaena kikowaena hoʻokaʻawale uila a hilinaʻi i ka pamu optical e hoʻoikaika i nā ion laser-active. ʻO kahi laʻana maʻamau ka neodymium i nā lasers YAG.

·Nā Noiʻi Hou:Ke kūkākūkā nei kahi noiʻi na A. Antipov et al. i kahi laser kokoke-IR solid-state no ka spin-exchange optical pumping. Hōʻike kēia noiʻi i nā holomua i ka ʻenehana laser solid-state, ʻoi aku hoʻi i ka spectrum kokoke-infrared, he mea koʻikoʻi ia no nā noi e like me ke kiʻi lapaʻau a me nā kelepona.

Heluhelu Hou Aʻe:He Laser Kokoke-IR no ka Spin-Exchange Optical Pumping

2. Nā Lasers Semiconductor

·ʻIke Laulā: Ma ke ʻano maʻamau, hiki i nā lasers semiconductor ke pōmaikaʻi mai ka pamu optical, ʻoi aku hoʻi i nā noi e pono ai ka ʻōlinolino kiʻekiʻe, e like me Vertical External Cavity Surface Emitting Lasers (VECSELs).

·Nā Hoʻomohala Hou: ʻO ka hana a U. Keller ma nā hui alapine optical mai nā lasers solid-state ultrafast a me semiconductor e hāʻawi i ka ʻike i ka hana ʻana o nā hui alapine paʻa mai nā lasers solid-state diode-pumped a me semiconductor. He mea nui kēia holomua no nā noi ma ka metrology alapine optical.

3. Nā Lasers Kinoea

·ʻO ka hoʻopili ʻana i ka ʻike maka i nā lasers kinoea: Hoʻohana kekahi mau ʻano lasers kinoea, e like me nā lasers mahu alkali, i ka hoʻopili ʻana i ka ʻike maka. Hoʻohana pinepine ʻia kēia mau lasers i nā noi e pono ai nā kumu kukui kūlike me nā waiwai kikoʻī.

Nā Kumu no ka Pumping Optical

Nā kukui hoʻokuʻuʻO ka mea maʻamau i nā lasers i hoʻoulu ʻia e ke kukui, hoʻohana ʻia nā kukui hoʻokuʻu no ko lākou mana kiʻekiʻe a me ka laulā ākea. Ua hoʻomohala ʻo YA Mandryko et al. i kahi kumu hoʻohālike mana o ka hana hoʻokuʻu arc impulse i nā kukui xenon pumping optical media ikaika o nā lasers solid-state. Kōkua kēia kumu hoʻohālike i ka hoʻonui ʻana i ka hana o nā kukui pumping impulse, he mea nui no ka hana laser kūpono.

Nā Diode Laser:Hoʻohana ʻia i nā lasers diode-pumped, hāʻawi nā diodes laser i nā pono e like me ka hana kiʻekiʻe, ka nui compact, a me ka hiki ke hoʻonohonoho pono ʻia.

Heluhelu hou aku:He aha ka diode laser?

Nā kukui uilaʻO nā kukui uila he mau kumu kukui ākea a ikaika hoʻi i hoʻohana pinepine ʻia no ka hoʻoulu ʻana i nā lasers solid-state, e like me ka ruby ​​a i ʻole Nd:YAG lasers. Hāʻawi lākou i kahi pahū kukui kiʻekiʻe e hoʻonāukiuki i ka medium laser.

Nā kukui ʻākuhiE like me nā kukui uila akā i hoʻolālā ʻia no ka hana mau, hāʻawi nā kukui arc i kahi kumu paʻa o ka mālamalama ikaika. Hoʻohana ʻia lākou i nā noi kahi e pono ai ka hana laser nalu mau (CW).

Nā LED (Nā Diode Hoʻopuka Mālamalama)ʻOiai ʻaʻole maʻamau e like me nā diode laser, hiki ke hoʻohana ʻia nā LED no ka pamu optical i kekahi mau noi mana haʻahaʻa. He pono lākou ma muli o ko lākou ola lōʻihi, ke kumukūʻai haʻahaʻa, a me ka loaʻa ʻana i nā nalu like ʻole.

LāMa kekahi mau hoʻonohonoho hoʻokolohua, ua hoʻohana ʻia ka lā i hoʻopaʻa ʻia ma ke ʻano he kumu pamu no nā lasers i hoʻopili ʻia e ka lā. Hoʻohana kēia ʻano hana i ka ikehu o ka lā, e lilo ia i kumu hou a kūpono hoʻi i ke kumukūʻai, ʻoiai ʻaʻole ia he mea hiki ke kaohi ʻia a emi iki ka ikaika ke hoʻohālikelike ʻia me nā kumu kukui artificial.

Nā Diode Laser i Hoʻopili ʻia me ka FiberʻO kēia nā diode laser i hoʻopili ʻia i nā olonā optical, e hāʻawi ana i ke kukui pamu me ka ʻoi aku ka maikaʻi i ka medium laser. He mea pono loa kēia ʻano hana i nā lasers fiber a i nā kūlana kahi e koʻikoʻi ai ka hāʻawi pololei ʻana o ke kukui pamu.

Nā Lasers ʻē aʻeI kekahi manawa, hoʻohana ʻia kekahi laser e pamu i kekahi. No ka laʻana, hiki ke hoʻohana ʻia kahi laser Nd: YAG i pāpālua ʻia i ke alapine (frequency-dual) e pamu i kahi laser dye. Hoʻohana pinepine ʻia kēia ʻano hana ke koi ʻia nā nalu kikoʻī no ke kaʻina hana pamu i hiki ʻole ke hoʻokō maʻalahi ʻia me nā kumu kukui maʻamau.
