390 nm igufi ya linewidth inshuro ebyiri fibre laser

Itsinda rya Erbium ritezimbere, ridafite uburyo bwo kwiringira, imbaraga nyinshi 390 nm ya laser (EFA-FHG-390).EFA-FHG-390 ikurikirana ikoresha 1560 nm fibre DFB laser hamwe na kHz umurongo wa kHz nkisoko yimbuto.Byose bya fibre amplifier byongera imbaraga za laser.390 nm laser iboneka binyuze mukubye kabiri inshuro ebyiri za polarisiyasi ya kirisiti hamwe na gahunda yahinduwe ya casade resonant inshuro ebyiri.Ugereranije na lazeri ya diode, urukurikirane rwa EFA-FHG-390 rufite ibiranga umurongo muto wa lazeri (ubugari bwumurongo wa Lorentz <50 kHz), nta buryo bwo gusimbuka munsi yubushyuhe bwinshi nubushyuhe bwo guhindagurika, ubuziranenge bwa laser (M² <1.3 ), hamwe nimbaraga nini zisohoka.
