LN–Q Whakawhiti Crystal

Whakaahuatanga Poto:

Kei te whakamahia nuitia a LiNbO3 hei kaihuri hiko me te Q-whakawhiti mo Nd:YAG, Nd:YLF me Ti:Sapphire lasers tae atu ki nga mea whakarereke mo te muka optics. Ka whakarārangihia e te ripanga e whai ake nei nga tohu o te karaihe LiNbO3 angamaheni i whakamahia hei whakahuri-Q me te whakahuri EO whakawhiti.

Whakaahuatanga Hua

Ka horahia te rama ki te tuaka-z, ka pa te mara hiko ki te tuaka-x. Ko nga taurangi hiko-optic o LiNbO3 ko: r33 = 32 pm / V, r31 = 10 pm / V, r22 = 6.8 pm / V i te auau iti me te r33 = 31 pm / V, r31 = 8.6 pm / V, r22 = 3.4 pm/V i te auau hiko teitei. Ko te ngaohiko haurua ngaru: Vπ=λd/(2no3r22L), rc=(ne/no)3r33-r13.LiNbO3 he karaihe acousto-optic pai hoki ka whakamahia mo te ngaru acoustic wave (SAW) angiangi me te AO modulators. Ka whakarato a CASTECH i nga tioata LiNbO3 karaehe oro (SAW) i roto i te angiangi, i te tapatapahi poua, i nga waahanga kua oti me nga mea hanga ritenga.
