Cov pab pawg Suav tau tsim tsa 1.2μm band high-fais fab ziab raman fiber ntau laser

Ib pab neeg Suav tau tsim tsa 1.2μm band muaj lub zog ramanFiber laser

Laser kom muaj txiaj ntsigKev khiav hauj lwm nyob rau hauv 1.2μm band muaj qee cov kev siv tshwj xeeb hauv photodynamic txoj kev kho, biomedical kuaj mob, thiab kev pom zoo oxygen. Ib qho ntxiv, lawv tuaj yeem siv los ua cov twj tso kua mis rau cov parametric tiam ntawm mid-infrared lub teeb thiab rau tsim kom pom kev lub teeb ci los ntawm zaus doubling. Lasers nyob rau hauv lub 1.2 μm band tau ua tiav nrog sib txawvKhoom-Lub Xeev Lasers, suav nroglasmicoductor lasers, Pob zeb diamond Raman lasers, thiab lasers fiber ntau. Ntawm peb lub pas dej no, fiber laser muaj qhov zoo ntawm cov qauv yooj yim thiab kev xaiv zoo ua kom tsim tau 1.2μm band laser.
Tsis ntev los no, pab neeg tshawb fawb tau coj los ntawm xibfwb teeb PU ZHOT nyob hauv Suav teb yog txaus siab rau cov roj muaj zog siab hauv 1.2μm band. Cov Hluav Taws Xob Cov Hluav Taws Xob Tam Sim NolasersFeem ntau yog Ytterbium-doped fiber ntau lasers nyob rau hauv tus qib 1 W. Lawv cov haujlwm ua haujlwm rau Raman Fiber Laser ntawm 1.2μm WaveBand, "yog Luam tawm nyob rau hauv FrontiersOptoelectronics.

Daim duab. 1: (a) Kev sim ua kev sim ntawm lub zog raman raman fiber ntau tshaj thiab (b) PDF: Phosphorus-doped fiber; QBH: Quartz loj; WDM: wavelength division multxer; SFS: Superfuloratorcent fiber ntau lub hauv paus; P1: Chaw nres nkoj 1; P2: Chaw nres nkoj 2. P3: Qhia tau tias: Zhang Yang linan Fiber ntau Al. Frontasers ntawm Optoelectronics (2024).
Lub tswv yim yog los siv cov txiaj ntsig Raman ua rau muaj kev vam meej ua kom muaj fiber ntau ntxiv kom tsim lub zog high-fais fab hauv 1.2μm band. Kev ua kom muaj zog Raman tawg yog qhov kev txiav txim siab thib peb uas tsis yog waverks kom ntev ntev.

Daim duab 2: tunable random rfledit spectra ntawm (a) 1065-1074 nm thiab (b) 1077 nm waversths (Δλ yog hais txog 3 DB Linewidth). Tau qhov twg los: Zhang Yang li al.
Cov kws tshawb fawb tau siv cov nyhuv raman scatuling cuam tshuam hauv phosphorus-doped Heaped HePed Htterbium-doped fiber ntawm 1 μm band. Ib lub teeb liab Raman nrog lub zog ntawm txog 735.8 W tau txais ntawm 1252.7 nm, uas yog qhov tso zis ntau tshaj plaws ntawm lub 1.2 μm band fiber ntau laser tau tshaj tawm rau hnub tim.

Daim duab 3: (a) Qhov siab tshaj plaws tso zis lub zog thiab cov tso zis tso zis tawm ntawm cov teeb liab sib txawv wavelengths. (b) tag nrho cov zis tawm ntawm cov paib sib txawv wavelengths, hauv DB (Δλ yog hais txog 3 DB LINEWIDTH). Tau qhov twg los: Zhang Yang li al.

Daim duab: 4: (a) lub zog hloov kho ntawm lub zog hluav taws xob siab Raman Fiber amplifier ntawm lub wavelengting ntawm 1074 nm. Tau qhov twg los: Zhang Yang li al.
