Using spectra and Amplitude to stabilize an injection locked laser
An unstable laser can be stabilized by being injection locked by a more stable laser. However, this method is limited because the injection lock only functions when the natural frequencies of both lasers are close together. When the unstable laser drifts too far, it ceases to be stabilized. By analysing the spectral output of the laser, or by analysing the over all power output, we can provide active feedback to stabilize the injection lock.
