Abstract Lithium niobate and potassium niobate crystals of near-stoichiometric composition were grown with the help of the Czochralski method with liquid and ceramic charging. Birefringence of the grown lithium niobate sample is Δn = 1.5 at 1 THz frequency, pleochroism in absorption on 1 THz frequency makes preferable the using of the extraordinary wave because of the lower absorption coefficient (14 cm−1). The absorption coefficient for the grown crystal of potassium niobate is 24 cm−1 at 1 THz frequency.

使用直拉法生长铌酸锂和铌酸钾单晶，液体和陶瓷充电

摘要 铌酸锂和铌酸钾晶体的接近化学计量组成是在直拉法的帮助下生长的，液体和陶瓷充电。生长的铌酸锂样品在 1 THz 频率下的双折射为 Δn = 1.5，在 1 THz 频率上吸收的多色性使得由于吸收系数较低（14 cm-1）而更适合使用非常波。在 1 THz 频率下，生长的铌酸钾晶体的吸收系数为 24 cm-1。
