Semiconductor lasers |
| abstract |
In a semiconductor laser comprising a body of semiconductor laser material which is caused to radiate coherent light by a pumping input, at least two electrodes are provided adjacent the reflective end surfaces or longitudinal edges and a control voltage is impressed across the electrodes to reduce multifrequency modes to a single central frequency mode or to a central frequency mode with a minority of side band modes. |
