Berger, J; Scifres, D R

This patent describes a laser consisting of an active medium in a resonant optical cavity. A first laser source emits a laser light beam so as to direct the beam into an end of the active medium, the active medium thereby having an optically pumped volume portion allowing oscillation of only single desired transverse cavity mode so as to produce a coherent light output, the coherent light output having an intensity. A second laser source emits a beam of laser light so as to direct additional laser light into a side of the active medium and thereby amplify the intensity of the coherent light output effectively eliminating spiking and delays. The laser also has means for modulating at least one of the laser sources at a high frequency rate with well-controlled high-quality pulses thereby providing modulation of the coherent light output in a stable transverse cavity mode.
