Analysis of Hysteresis Behavior of the Lock-In Range in a Zeeman Ring Laser

Key Points

• This research aims to explore the hysteresis behavior in the lock-in range of a Zeeman ring laser and develop a theoretical model for its description.
• Experimental studies on the hysteresis of the lock-in range in a Zeeman ring laser.
• Development of a new model accounting for the absorption of laser radiation in the resonator mirrors.
• Derivation of expressions for coupling coefficients of counterpropagating waves due to absorption gratings.
• Numerical simulations based on the proposed model to validate experimental findings.
• Wide hysteresis regions in the lock-in range have been observed experimentally.
• The proposed model qualitatively agrees with the experimental results.
• The model also successfully accounts for the diffraction effects due to absorption in the resonator mirrors.
