A 1 W injection locked cw titanium:sapphire laser
E. A. Cummings, M. S. Hicken, S. D. Bergeson
We report an injection-locked cw titanium:sapphire ring laser at 846 nm. It produces 1.00 W in a single frequency when pumped with 5.5 W. Single frequency operation requires only a…

Exploring closed-loop feedback control using experiments in optics
K. A. Jensen, R. J. Larson, S. D. Bergeson +1
We present two experiments in closed-loop feedback control. In the first experiment, students control the pointing angle of a laser to "lock" the laser onto a "target." In the seco…
