| Abstract: | The mode of coherent combination of laser arrays is set up based on self-imaging confocal resonator.One-dimensional coherent combination and two-dimensional coherent combination are calculated and the intensity distribution of the field is obtained.Spatial filter used for mode selection is studied.Besides,the effect of the place and the width of the special filter on the coherent combination is analyzed,which gives the basis to the experiment. |
| Keywords: | Coherent combination Mode selection Self-imaging confocal resonator patial filter |
