    • A process for producing a purified aqueous hydrogen peroxide solution, comprising passing a charged aqueous hydrogen peroxide solution containing impurities through a purifier tower packed with an ion exchange resin, a chelate resin or an adsorption resin to thereby purify the charged aqueous hydrogen peroxide solution, wherein there are provided a feed pump of given output capable of causing the charged aqueous hydrogen peroxide solution to flow to the purifier tower and further a flow sensor capable of sensing a flow rate of charged aqueous hydrogen peroxide solution being fed to the purifier tower and wherein the output of the feed pump is controlled in cooperation with the flow sensor so as to bring the charged aqueous hydrogen peroxide solution into contact with the ion exchange resin, chelate resin or adsorption resin while maintaining the flow of charged aqueous hydrogen peroxide solution at a constant rate. In this process, not only can remaining of bubbles in the purifier tower be avoided but also pressure and temperature increases can be prevented in the purification operation, so that the aqueous hydrogen peroxide solution can be brought into contact with the ion exchange resin, etc. safely and efficiently.

    • An optical wavelength converting apparatus comprises an optical wavelength converting device, which is constituted of a crystal of a nonlinear optical material and converts a wavelength of an incident fundamental wave into a different wavelength, a holder, which is constituted of a metal and to which the optical wavelength converting device is adhered and secured, and a device for adjusting the temperature of the region containing the optical wavelength converting device. The optical wavelength converting device is secured to the holder by adhering only the surface of the optical wavelength converting device to the holder, which surface is normal to the direction of a crystallographic axis that has a coefficient of thermal expansion most different from the coefficient of thermal expansion of the metal constituting the holder among the coefficients of thermal expansion of the crystallographic axes of the optical wavelength converting device. The optical wavelength converting device is thus reliably secured to the holder and prevented from breaking or being distorted due to a change in environmental temperature, and the accuracy, with which the temperature of the optical wavelength converting device is adjusted, is kept high.
    • 光波长转换装置包括由非线性光学材料的晶体构成并将入射基波的波长转换为不同波长的光波长转换装置,由金属构成的保持器, 光波长转换装置被粘附和固定,以及用于调节包含光波长转换装置的区域的温度的装置。 光波长转换装置通过仅将光波长转换装置的表面粘附到保持器固定到保持器,该保持器的表面垂直于具有与热系数最不同的热膨胀系数的结晶轴方向 构成保持器的金属在光波长转换装置的结晶轴的热膨胀系数中的膨胀。 因此,光波长转换装置被可靠地固定到保持器,并且防止由于环境温度的变化而导致的断裂或变形,并且将光学波长转换装置的温度调节的精度保持为高。
