390 nm haiki linewidth alapine palua fiber laser

Hoʻokumu ka hui Erbium i ka haiki, non mode hopping, mana kiʻekiʻe 390 nm laser series (EFA-FHG-390).Hoʻohana ʻo EFA-FHG-390 i ka laser 1560 nm fiber DFB me ka laina laina kHz ma ke ʻano he kumu hua.Hoʻonui ʻia ka mana laser a pau-fiber amplifier.Loaʻa ka laser 390 nm ma o ka pālua pinepine ʻana o ka aniani polarization periodic a me ka hoʻololi pinepine ʻana o ka cascade resonant frequency pālua.Ke hoʻohālikelike ʻia me nā lasers diode, ʻo ka EFA-FHG-390 series nā hiʻohiʻona o ka laina laina laina lorentz (Lorentz line width <50 kHz), ʻaʻohe mode lele ma lalo o kahi ākea nui o ka mahana a me nā kūlana vibration, ʻoi aku ka maikaʻi o ka beam laser (M² <1.3). ), a me ka mana puka nui.
