Cr4+:YAG –He mea kūpono no ka hoʻololi ʻana i ka Q
Hōʻike huahana
Ua makemake ʻia ʻo Crystal Passive Q-switch no ka maʻalahi o ka hana ʻana a me ka hana, ke kumu kūʻai haʻahaʻa, a me ka nui o ka ʻōnaehana hoʻemi a me ke kaumaha.
Cr4+: ʻO YAG ka mea paʻa kemika, pale UV a paʻa.Cr4+: E hana ana ʻo YAG ma luna o nā ʻano wela a me nā kūlana.
ʻO ka conductivity thermal maikaʻi o Cr4 +: YAG ua kūpono no nā noi mana kiʻekiʻe.
Ua hōʻike ʻia nā hopena maikaʻi loa me ka hoʻohana ʻana iā Cr4+:YAG ma ke ʻano he passive Q-switch no nā lasers Nd:YAG.Ua ana ʻia ke kahe o ka saturation ma kahi o 0.5 J/cm2.ʻO ka manawa hoʻihoʻi lohi o 8.5 µs, i hoʻohālikelike ʻia me nā mea kala, pono ia no ka hoʻopau ʻana i ka laka ʻano.
Q-hoʻololi pulsewidths o 7 a 70 ns a me ka hana hou ana a hiki i 30 Hz ua loaʻa.Hōʻike nā hoʻāʻo ʻo Laser Damage Threshold iā AR i uhi ʻia i ka Cr4+: YAG passive Q-switch ua ʻoi aku ma mua o 500 MW/cm2.
ʻOi aku ka maikaʻi o ka optical a me ka homogeneity o Cr4 +: YAG.No ka hōʻemi ʻana i ka nalowale o ka hoʻokomo ʻana ua uhi ʻia nā kristal AR.Cr4 +: Hāʻawi ʻia nā kristal YAG me ke anawaena maʻamau, a me kahi ʻano o nā densities optical a me nā lōʻihi e kūlike i kāu mau kikoʻī.
Hiki ke hoʻohana ʻia no ka hoʻopaʻa ʻana meNd:YAGaNd, Ce:YAG, ka nui maʻamau e like meD5*(85+5)
Pono o Cr4+:YAG
● Paʻa kemika kiʻekiʻe a me ka hilinaʻi
● He maʻalahi ke hoʻohana ʻia
● paepae pōʻino kiʻekiʻe (>500MW/cm2)
● E like me ka mana kiʻekiʻe, ke kūlana paʻa a me ka Q-Switch passive paʻa
● lōʻihi ke ola manawa a me ka maikaʻi thermal conductivity
