Hoʻopuka ʻelua fiber i ka laser alapine hoʻokahi ma 780 nm Kiʻi Hōʻike

ʻO ka hoʻopuka ʻana i ka fiber pālua hoʻokahi laser frequency ma 780 nm

Hoʻohālike:

ʻO ka wehewehe pōkole:

Hoʻokumu ka hui Erbium i ka laser fiber frequency ʻelua me ka mana kiʻekiʻe loa a hiki i 1W/2W no Gravimeter gradiometer e pili ana i ka Rb cold atom.Hiki ke laka ʻia ka ʻokoʻa alapine ma waena o nā ala ʻelua e ka beat frequency/phase locking technique.Hiki ke kauoha ʻia nā awa puka o 1560/780 nm laser, e hāʻawi ana i ke kumu kukui hana kiʻekiʻe no ka gravimeter, quantum optics a pēlā aku.Hoʻohui ʻia ka laser seed, amplifier a me ka pālua pālua ʻelua o ka laser ʻelua-kanal 1560 nm i kahi pahu hoʻoluʻu liʻiliʻi.Loaʻa i ka mīkini holoʻokoʻa kahi hoʻolālā paʻa, paʻa a hilinaʻi hoʻi ka hana, a hiki ke hele i ka vibration a me nā hoʻokolohua wela haʻahaʻa.

█Laina laina haiki<20 kHz(e like me 2 kHz)

█ʻO ka walaʻau haʻahaʻa haʻahaʻa koho (RIN <-130 dBc/Hz @ 100 kHz)

█Mana kiʻekiʻe (2W)

█ʻOi aku ka maikaʻi o ka lāʻau kukui (M² <1.1)

█Paʻa mana (PP<1% @25℃, <2% @15-35℃)

■Kiʻekiʻe a me ka haʻahaʻa wela hopena hopena

■ Paʻa pinepine ma lalo o ka hopena wela kiʻekiʻe a haʻahaʻa

■ Waihona wela haahaa kiekie

ʻO ka neʻe pinepine ʻana o ke kikowaena waena o 0 ℃ -50 ℃ ma kahi o 340 MHz, a ʻo ke kikowaena o 25 ℃ no 2 mau hola ma kahi o 40 MHz.

Ua hōʻike ka hoʻokolohua o ke kiʻekiʻe a me ka haʻahaʻa haʻahaʻa i ka mālama ʻana i ka neʻe ʻana o ka neʻe ʻana ma -30 ℃ -70 ℃ i ka hana maʻamau o ka laser ma hope o ka haʻalulu haʻahaʻa haʻahaʻa.

■ Paʻa mana RMS ma lalo o ka hopena wela kiʻekiʻe a haʻahaʻa

Ua ana 'ia ke kupaa o ke kanal mua ma kela me keia wahi wela ma ka hoao ana wela kiekie.ʻOi aku ka maikaʻi o ka mana paʻa o ka RMS 2-hola ma ka palena palena o 0 ℃ a me 50 ℃ ma mua o 0.2%

ʻOi aku ka maikaʻi o ka mana o ke kahawai ʻelua ma mua o 0.2% (kahi mahana hoʻokahi, RMS)

Loaʻa i ka hua ka mea i hoʻopaʻa ʻia i ka sweep sweep interface, a ʻo ka 780nm laser frequency sweep range ma kahi o 3.2GHz.

Ke koho ʻana i kahi kiko laka alapine kūpono a me ka hoʻomalu ʻana i kahi ʻokoʻa alapine kūpono a me ka neʻe pinepine ʻana ma waena o nā kaha ʻelua, hiki i nā kaha lua ʻelua 780 nm laser i hana ʻia e PreciLasers hiki ke hāʻawi i nā lasers āpau e pono ai no ka hoʻokolohua o rubidium atomic gravimeter.Hiki i ka huahana ke hoʻololi i ke kaiapuni maikaʻi a he koho maikaʻi loa ia no ke kumu laser o transportable atomic gravimeter.
