[Truncated] The aim of this project was to develop, characterise and utilise high power solid state lasers for ophthalmic applications. Currently, excimer lasers operating in the UV, are widely and successfully employed to perform corrective refractive surgery. A more robust solid state laser with an output wavelength also in the UV would provide an attractive alternative to the current technology. This project comprised two main objectives. The first objective involved the identification and development of an appropriate solid state laser to produce UV pulses. Two flash-lamp pumped, low repetition rate, Q-switched laser sources were investigated for this purpose. A Ti:sapphire and an Nd:YAG laser employing nonlinear optical crystals to convert the fundamental IR output wavelength into the UV were examined. For the Nd:YAG laser this meant generating the fifth harmonic wavelength of 213nm. In the case of the Ti:sapphire laser, an attempt was made to generate the fourth harmonic wavelength in the 210 - 220nm range.
