Ọkụ Diode Laser Edobere
Nkọwa ngwaahịa
N'iji ya na laser diode cavity mpụga nke ọdịnala, FECL (laser cavity cavity diode laser) enweghị ihe nwere ike ibugharị na nhazi ahụ.Ya mere, ọ na-enwe ike ịrụ ọrụ n'okpuru oke ọnọdụ okpomọkụ mgbanwe na ịma jijiji, ka na-enweghị mode-hop.
N'ịnabata teknụzụ nkwakọ ngwaahịa laser diode ngwa anya, otu Erbium mepụtara FECL n'ime obere ngwugwu urukurubụba.Ka ọ dị ugbu a na onye na-anya ụgbọ ala na-eme mkpọtụ na nnukwu modulation-bandwidth, Precilasers' FECL na-egosi eriri dị warara dị warara (< 10 kHz), mkpọtụ obere ike dị ala (<-150 dBc / Hz @ 100 kHz), na nnukwu bandwidth modulation (> 5MHz). ).
A na-eji FECL eme ihe n'ọtụtụ ebe dị ka elekere atomiki na-ebugharị, na mita ike ndọda, lattice anya, radar, nkwurịta okwu anya na-arụkọ ọrụ ọnụ, nghọta anya dị elu nke ọma, metrology quantum.
