Stabilization of Laser Frequency Based on the Combination of Frequency Locking and Power Balance Methods

Saeed Olyaee and Shahram Mohammad Nejad

Abstract:
In this study, a new laser frequency stabilizer based on the combination of power balance and frequency locking methods is presented. These methods have been widely used in the two-mode laser frequency stabilizers. But in this study, we design and simulate an optical setup and thermal cavity controller to improve the frequency stability of three-mode He-Ne laser. Stabilization of the secondary beat frequency (frequency locking) and amplitudes of three modes (power balance) cause standing position of them to be fixed in the gain profile. The results of simulations by SIMULINK indicate that thermal coefficient of the laser cavity and frequency stability are equal to 1.2 Hz/nm and 3 parts in 1010, respectively.
