Hoʻohālike: EFL-FHG-XX-YY-ZZ¹

ʻO ka wehewehe pōkole:

Hāʻawi ka pūʻulu Erbium i ka mana kiʻekiʻe, hoʻokahi-frequency tunable UV lasers mai 250 a 400 nm, no nā noi i nā ʻepekema quantum e like me nā ʻātoma anu, nā molekole ultra-anu, hoʻokahi-photon excitation o Rydberg atom a me ka maʻamau maʻamau.Loaʻa ka laser UV ma o ka hoʻohui ʻana i kahi mea hoʻonui fiber-fiber a pau i hua ʻia me ka laser linewidth ultra-narrow, kahi ʻāpana pālua pinepine-pālua me ka kristal PPLN a me kahi lua resonant hoʻonui cascaded.Loaʻa i kēia mau laser nā hiʻohiʻona o ka linewidth liʻiliʻi, linear polarization a me ke kani.Ma hope o ka mana ikaika, ʻoi aku ka liʻiliʻi o ka mana mana RMS o ka laser ma mua o 1.0% i loko o 3 mau hola.

Nā mea nui

● ʻO ka hoʻolālā maʻalahi hoʻokahi hele pinepine pālua

● High pono waho lua resonance alapinepine pālua

● mana kiʻekiʻe

● ka leo haʻahaʻa haʻahaʻa

● laina laina haiki

Nā noi

● Hoʻoulu ʻia ʻo Rydberg photon hoʻokahi o Rubidium atom (297 nm)

● ʻO ka hoʻoheheʻe ʻana i ka ion Beryllium (313 nm)

● Kākau paʻa (390 nm)

● Uaki ʻōpika calcium ion (397 nm)

● Ytterbium ʻātoma hoʻoluʻu (399 nm)
