Correction of the astigmatic laser beam |
| |
| Abstract: | Two mathods for the correction of astigmatic laser beam are proposed: Astigmatism can be compensated by controlling the sign of surface flatness or by inserting an inclined lens in laser system. General formula to calculate the astigmatism and compensating parameters has been derived. Theoretical calculation is in good agreement with the experimental results. |
