PURPOSE: To improve separation efficiency, by providing a infrared light source suitable for a laser utilizing isotope separating method and the control system thereof.
CONSTITUTION: This isotope separation apparatus is based on such knowledge that oscillation wavelength of 16μm band coincided with absorption wavelength of UF6 can be easily developed if lead calcogen type semiconductive diode laser is used and the wavelength can be accurately adjusted by the control of a current or an element temp. An infrared light source for separation is constituted from wavelength changeable lead calcogen type semiconductive diode laser and a means for monitoring the separation amount of an isotope selectively excited by laser beam irradiation from said light source is provided to control the oscillation wavelength of the diode laser so as to make a separation ratio max. A gas cell containing the isotope to be separated is provided to control the oscillation wavelength of the diode laser in such 2 manner that the part of laser beam from the diode laser is introduced to detect permeated beam and the absorption amount of the laser beam in the gas cell is made max.
