Abstract

The pulses of an excimer laser-pumped dye laser are coupled into a microscope and focused through a 1.25 aperture objective (Fig. 1). These pulses are used to perforate human red blood cells and pollen from maize. A plot of the diameter of the lesion on the cell membrane vs the wavelength shows a pronounced peak structure (Fig. 2).
