Feedback Single Frequency Fiber Laser

Single-frequency fiberlaser ili ndi mwayi waukulu kwambiri wotulutsa laser-frequency single-frequency laser wokhala ndi mizere yopapatiza.

Single-frequency fiber laser yomwe imaperekedwa ndi gulu la Erbium imagwiritsa ntchito ukadaulo wogawa mayankho kuti apange laser yolumikizana pafupipafupi pamapangidwe amtundu wonse.Ntchito ya single-frequency ndiyokhazikika komanso yothandiza potengera luso lapadera lopondereza pafupipafupi.Msonkhano wapadera umagwiritsidwanso ntchito kudzipatula kukhudzidwa kwa kugwedezeka kwachilengedwe kwakunja ndi kusintha kwa kutentha, potero kumapangitsa kuti kukhazikika kwa nthawi yaitali kumafupikitsidwe ndi kuchepetsa mzere wa mzere.Komanso motere, njira ya laser sichidzadumphidwa.Pakalipano, mphamvu zotulutsa mphamvu ndizoposa 10 mW, 40 mW ndi 10 mW pamagulu a 1 μm, 1.5 μm ndi 2 μm, motero.Kutalika kwa mawonekedwe ake kumasinthasintha ndipo kutalika kwa mzere kumakhala kosakwana 20 kHz.Kutalika kwa matenthedwe amtundu wa matenthedwe ndi okwera mpaka 0.8 nm ndipo kusinthasintha pafupipafupi kumatha kufika 3-5 GHz.Laser imakhalanso ndi kukhazikika kwamphamvu (RMS<0.5% @3 hrs) komanso mtengo wabwino kwambiri (M2 <1.05).Chifukwa chake, ma frequency fiberlaser omwe amaperekedwa ndi Precilasers ndiye chisankho chabwino kwambiri pafiziki ya atomu yozizira, makina opangira mphamvu kwambiri, zomverera komanso kugwiritsa ntchito lidar.
