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.]]>Balhorn, R., H. Kunzmann and F. Lebowsky,197211742744Chien, P.Y. and C.L. Pan,199162933935Eom, T.B., H.S. Choi and S.K.
