390 nm kunkuntar layin nisa mita ninki biyu fiber Laser

Ƙungiyar Erbium tana haɓaka kunkuntar, yanayin hopping, babban ikon 390nm Laser jerin (EFA-FHG-390).EFA-FHG-390 jerin amfani da 1560 nm fiber DFB Laser tare da kHz linewidth a matsayin iri tushen.All-fiber amplifier yana ƙara ƙarfin laser.Ana samun Laser 390nm ta hanyar mitar ninki biyu na kristal polarization na lokaci-lokaci da tsarin sauya mitar mitar mitar cascade.Idan aka kwatanta da laser diode, jerin EFA-FHG-390 yana da halaye na kunkuntar layin layin laser (Layin layin Lorentz <50 kHz), babu yanayin tsalle a ƙarƙashin babban yanayin zafin jiki da yanayin girgiza, mafi kyawun ingancin katako na Laser (M² <1.3). ), da kuma babban ƙarfin fitarwa.
