LN–Q Hoʻololi Crystal

ʻO ka wehewehe pōkole:

Hoʻohana nui ʻia ʻo LiNbO3 e like me nā modulators electro-optic a me nā Q-switch no Nd:YAG, Nd:YLF a me Ti: Sapphire lasers a me nā modulators no nā fiber optics.Hoʻopili ka papa ma lalo nei i nā kikoʻī o kahi aniani LiNbO3 maʻamau i hoʻohana ʻia ma ke ʻano he Q-switch me ka modulation EO transverse.
