  Most of the saturable absorbers commonly used to perform mode locking in
laser cavities affect the trigger conditions of laser oscillation, which
requires manually forcing the laser start-up by various means such as
polarization controllers. We present a procedure for designing a laser cavity
driven by a nonlinear optical loop mirror, which allows the laser to operate
optimally without interfering with the oscillation triggering conditions, thus
opening up possibilities for integration of this type of laser.
