Abstract

We produce minimally disruptive breakdown in water by using tightly focused 100-fs laser pulses and demonstrate the potential use of this technique in microsurgery of the eye. Using time-resolved imaging and piezoelectric pressure detection, we measure the magnitude and speed of propagation of the pressure wave produced in the breakdown. Compared with breakdown with longer pulses, here there is a much lower energy threshold for breakdown of 0.2µJ , a smaller shock zone diameter (11µm for 1-µJ pulses), and consistent energy deposition.

  11. Water is a good basic model for studies of breakdown and shock wave propagation in tissue for two reasons: First, breakdown thresholds for femtosecond pulses differ little from one transparent material to another (see text). Second, shock dynamics are similar in water and tissue because tissue is composed largely of water and thus has nearly the same density, compressibility, and sound velocity. The similarity of the shock wave dynamics has been confirmed by experiments comparing water with bovine corneas T. Juhasz, X. H. Hu, L. Turi, and Z. Bor, Lasers Surg. Med. 15, 91 (1994).

  15. The larger value of the energy threshold in water is likely due to spherical abberation introduced by focusing through a 180-µm-thick window in the water cell.
