Nd:YVO4 – Nā Lasers Mokuʻāina Paʻa Paʻa Diode
Hōʻike huahana
Nd:YVO4 hiki ke hana i nā lasers IR ikaika a paʻa, ʻōmaʻomaʻo, polū me ka hoʻolālā ʻana o Nd:YVO4 a me nā kristal pālua pālua.No nā noi i makemake ʻia ai ka hoʻolālā paʻakikī a me ka hoʻopuka hoʻokahi-longitudinal-mode, hōʻike ʻo Nd:YVO4 i kona mau pono kūikawā ma mua o nā kristal laser i hoʻohana mau ʻia.
Pono o Nd:YVO4
● Haʻahaʻa lasing paepae a me kiʻekiʻe slope pono
● Nui hoʻoulu ʻia emission cross-section ma lasing wavelength
● Kiʻekiʻe absorption ma luna o ka laulā hawewe lōʻihi bandwidth
● Optitically uniaxial a nui birefringence emits polarized laser
● Ke hilinaʻi haʻahaʻa i ka lōʻihi o ka nalu a hoʻomaka i ka puka ʻana o ke ʻano hoʻokahi
