Abstract:

Negative branch unstable resonators have the advantage over positive branch unstable resonators of not being as susceptible to mirror misalignment effects. Specifically, as a negative branch resonator mirror is misaligned, the angle at which lasing ceases is significantly larger. The theoretical cease lasing angle is derived using ray optics. The experimental cease-lasing angle is found to lie between this theoretical angle and the best case angle.
