Enhanced laser conditioning using temporally shaped pulses
Abstract
Laser conditioning was investigated as a function of the temporal shape and duration of 351-nm, nanosecond pulses for fused-silica substrates polished via magnetorheological finishing. Here, the aim is to advance our understanding of the dynamics involved to enable improved control of the interaction of laser light with the material to optimize laser conditioning. Gaussian pulses that are temporally truncated at the intensity peak are observed to enhance laser conditioning, in comparison to a Gaussian pulse shape.

Figure 1: Laser‐induced–damage testing (LIDT) results versus pulse duration and shape. The 1‐on‐1 (green) Gaussian results fit to a power‐ law pulse‐width scaling of $$\tau^{0.52}$$ and the canonical $$\tau^{0.5}$$ is plotted (solid line). The N‐on‐1 (blue) results indicate that laser conditioning is strongly dependent on pulse shape and duration (Gaussianmore »
