The frequency-variation shifts of a He-Ne Laser stabilized by saturated
absorption of iodine 127I2 arising from the modulation amplitude were
determined. Modulation depths of the range 4 to 8 MHzp-p were chosen. At the
recommended operating temperature of 15 ◦C for the iodine cell, the linear
coefficients have been determined from a sets of matrix measurements for
individual components d, f, g, h, i, j in the range of modulation amplitude for
test laser.
