ʻO ke ala ʻenehana koʻikoʻi o nā lasers haiki-linewidth hiki

ʻO ke ala ʻenehana nui onā lasers ākea ākea hiki ke hoʻokō ʻia

ʻO nā ala ʻenehana nui o tunablenā laser ākea laina haikime nā lua waho semiconductor

ʻO nā lasers narrow-linewidth Tunable ke kumu no nā noi ākea i nā kula e like me ka atomic physics, spectroscopy, quantum information, coherent communication, remote sensing, a me ke ana pololei. Ma kēia mau kahua, ʻoi aku ka maʻalahi, ʻoi aku ka liʻiliʻi, ʻoi aku ka liʻiliʻi o ka laina laina a me ka nui o ka hoʻopaʻa ʻana i nā lasers e hoʻomau i nā noi hou o kēia ʻenehana.

I loko o nā makahiki he 50 i hala iho nei, ʻo ka mōʻaukala o kakumu kukui hoʻolimaUa hōʻike nui ʻo TLS Laser i ka hoʻomohala ʻana o ka ʻenehana laser. Ua pani ʻia nā laser dye mua e nā laser cavity diode o waho (ECDLs), aʻo nā ʻōnaehana mana kiʻekiʻe e hoʻomalu ʻia e nā lasers solid-state tunable (e like me nā lasers titanium-sapphire) a i ʻole nā ​​lasers Nd: YAG i hoʻololi pinepine ʻia me ka hoʻohana ʻana i nā optical parametric oscillators (OPO). ʻO nā lasers diode me ka ʻole o nā lua waho paʻa ua hoʻopiha i ka hopena haʻahaʻa haʻahaʻa a me ka haʻahaʻa haʻahaʻa o ka mākeke me nā diodes DFB Laser a me DBR, me ka laulā laina e like me 500kHz. I kēia mau lā, ua hoʻomaka nā laser fiber a me nā lasers fiber frequency variable e hoʻololi i nā ʻōnaehana solid-state me nā hoʻolālā like ʻole, e hāʻawi ana i ka mana kiʻekiʻe a me ka tunability ʻoi aku, a i ʻole ka laulā laina haiki. I kēia mau lā, hiki i ka puka ʻana mai o nā pulupulu alapine ke hoʻokō i nā lasers i hoʻopaʻa pinepine ʻia i kēlā me kēia nalu i ka mālama ʻana i ka paʻa a me ka pololei. Eia naʻe, ʻoiai kēia, ka lua waholaser semiconductorke hoʻomau nei i kona kūlana ma ke ʻano he kumu kukui maʻamau i hoʻohana ʻia i nā laboratories he nui ma muli o kona maʻalahi, multi-functionality, hana hanohano a haʻahaʻa loa ke kumu kūʻai.

I kēia manawa, ua hoʻohana nui ʻia nā lasers ākea ākea me nā semiconductors lua waho i:

ʻO ka hoʻoluʻu laser a me ka hopu ʻana

ʻO Bose-Einstein condensation

Quantum Optics: Māmā i hoʻopili ʻia

Electromagnetic malamalama a me ka māmā māmā

Nā kūlana manawa a me ka pinepine

ʻO ke kiʻi kiʻi laser

Hoʻokumu pinepine ʻia nā lasers narrow-linewidth Tunable me kahi mea hoʻoponopono, kahi diode laser a me kahi module koho alapine. No ka laʻana, hoʻohana ʻia nā gratings no ke koho alapine laser a me ke kani ʻana, a i ʻole nā ​​kānana e pili ana i ke ʻano o ka maka o ka pōpoki, a me nā mea ʻē aʻe. No ka hoʻokō ʻana i ke kūpaʻa kiʻekiʻe o ka laser, hiki ke hoʻohui ʻia nā ʻano like ʻole o nā modula paʻa pinepine laser. No ka laʻana, ma ka hoʻohana ʻana i ka ʻenehana hoʻopaʻa pinepine PDH e hoʻopaʻa i ka lōʻihi o ka hawewe laser ma ka lua optical super-stable, hiki ke hōʻemi ʻia ka laina laina o ka laser i ke kiʻekiʻe o 1 Hz, a hiki i ke kūpaʻa alapine ke hiki i <3 × 10-15 @ 1 s.
