Mid-infrared single-frequency fiber laser

Chitsanzo:

Kufotokozera Kwachidule:

Gulu la Erbium limapanga laser-fiber single-pass differential frequency laser (FA-SDFG) imakulitsa kutalika kwa mafunde mpaka Mid-infrared range.Mndandanda wa FA-SDFG umagwiritsa ntchito mzere wopapatiza kwambiri wa DFB ngati gwero la mbewu.All-fiber amplifier amakulitsa mphamvu ya laser.The periodic polarization crystal imatengedwa kuti ipange laser yamphamvu yosiyana kwambiri.Mafunde amtundu wa FA-SDFG akuphimba 2.4-4.0 um.Laser ili ndi mawonekedwe amtundu wopapatiza wa laser linewidth (Lorentz linewidth <10kHz), palibe njira yodumphira pansi pamitundu yambiri ya kutentha ndi kugwedezeka, mtundu wabwino kwambiri wa laser mtengo (M² <1.2), mphamvu yotulutsa kwambiri komanso phokoso lotsika kwambiri.

Technical Parameter

Zolemba Zamalonda

Mapulogalamu

● Kumverera patali

● Laser sipekitiramu

● Kuzindikira gasi

Zofunika Kwambiri

● Mphamvu zazikulu, utali wocheperako, kusinthasintha, kusinthasintha kwa mzere

● Palibe kudumphadumpha

● Kutentha kwakukulu ndi kutsika, kugwedezeka kwamphamvu

● Beam yabwino kwambiri (M² <1.2)
