Self-pulsing in medium-power He-Ne lasers
Abstract
An analytical model was developed to describe self-pulsing in medium-power He-Ne laser. The numerical results show that the oscillating modes can be coupled by population pulsation such that the resonant dispersion can be linearized as required for undistorted pulse propagation while simultaneously satisfying the uniform gain condition across the inhomogeneous bandwidth. The analyses also predict an increase in pulse velocity as well as power output as the laser becomes locked. Experimental measurements indeed show that when the laser is switched from partially unlocked to fully self-locked operation, the pulse velocity increases by about 9 part in 1,000,000 and the average output power increases by about 0.5 percent.
