− | The histogram above was fitted with a second order polynomial and used to correct for fluctuations in the laser energy from row to row. | + | The histogram above was fitted with a second order polynomial and used to correct for fluctuations in the laser energy from row to row. Stacking laser pulses on top of each other increases the amount of diamond material removed within the region of overlap. This method was used to account for laser energy fluctuations while deferentially ablating diamond to within ±0.5µm surface variation. |
