Abstract This paper compares the relative merits of the continuous wave argon-pumped dye laser and the pulsed gold-vapour laser as used clinically for photodynamic therapy. At comparable power and energy outputs, the biological effect of the two appears to be the same. However, for 1 W output (a suitable level for clinical use), the gold laser is simpler and easier to install and run, although it requires a larger diameter fibre for light delivery (0.6 mm v. 0.2 mm). The wavelength of the dye laser is tunable, whereas that of the gold is not, although the gold laser can be easily converted to a copper-vapour laser which can pump a tunable dye laser.
