METHOD FOR CONTROLLING THE ABSOLUTE VALUE OF THE WAVELENGTH OF SPECIAL LASERS WITH INTERIOR MIRRORS IN HE-NE IN TWO MODES

摘要

P Method for controlling the absolute value of the frequency of special lasers with interior mirrors, in He-Ne, in two modes in which a mixture of filling gas is used consisting of helium and neon not containing of isotopes, characterized in that the absolute value of the laser frequency is determined from the measured value of the difference in mode intensities and using an initial calibration measurement. /P
