Effect of frequency modulation amplitude on Iodine stabilized He-Ne Laser, at λ ≈ 633nm

Abstract

The frequency-variation shifts of a He-Ne Laser stabilized by saturated absorption of iodine 127 I 2 arising from the modulation amplitude were determined. Modulation depths of the range 4 to 8 MHz p-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.
