ʻO ke ala loea nui o nā lasers narrow-linewidth hiki ke hoʻololi ʻia

ʻO ke ala ʻenehana nui onā lasers laina haiki hiki ke hoʻololi ʻia

ʻO nā ala loea nui o ka tunablenā lasers laina haikime nā lua waho semiconductor

ʻO nā lasers narrow-linewidth hiki ke hoʻololi ʻia ke kumu no nā noi ākea ma nā kahua e like me ka physics atomic, spectroscopy, ʻike quantum, kamaʻilio kūlike, ʻike mamao, a me ke ana pololei. Ma kēia mau kahua, ʻo nā lasers linewidth maʻalahi, ʻoi aku ka liʻiliʻi, ʻoi aku ka haiki a me ka laulā tuning ākea e hoʻomau i ka hoʻokele ʻana i nā noi hou o kēia ʻenehana.

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

I kēia manawa, ua hoʻohana nui ʻia nā lasers linewidth haiki hiki ke hoʻololi ʻia me nā semiconductors lua waho i:

Hoʻoluʻolu a me ka hopu ʻana o ka laser

Hoʻohuihui Bose-Einstein

ʻIke Kuantum: Mālamalama i hoʻopaʻa ʻia

ʻIke electromagnetic a me ke kukui lohi

Nā kūlana manawa a me ke alapine (pinepine)

ʻIke laser

ʻO ka maʻamau, ua haku ʻia nā lasers narrow-linewidth tunable me kahi mea hoʻokele, kahi diode laser a me kahi module koho alapine. No ka laʻana, nā gratings i hoʻohana ʻia no ke koho alapine laser a me ka hoʻonohonoho ʻana, a i ʻole nā ​​​​kānana e pili ana i ke ʻano o ka maka o ka pōpoki, a pēlā aku. ʻO nā ʻano koʻikoʻi o nā lasers narrow-linewidth tunable me nā semiconductors lua waho e komo pū me ka laina laser narrow, ka haʻahaʻa alapine haʻahaʻa, a me ka laulā tuning ākea, a pēlā aku. A hilinaʻi kēia mau ʻano koʻikoʻi i kahi kaapuni hoʻokele laser maikaʻi loa, ke kūpaʻa mechanical holoʻokoʻa o ka laser, a me ke kumumanaʻo o ke koho alapine. No ka hoʻokō ʻana i ke kūpaʻa alapine kiʻekiʻe o ka laser, hiki ke hoʻohui ʻia nā ʻano modula laka alapine laser like ʻole. No ka laʻana, ma ka hoʻohana ʻana i ka ʻenehana hoʻopaʻa alapine PDH e laka i ka nalu laser ma ka lua optical super-stable, hiki ke hoʻemi ʻia ka laina o ka laser i ka pae o 1 Hz, a hiki i ke kūpaʻa alapine ke hiki i <3 × 10-15 @ 1 s.
